RK3588 Custom Linux BSP, WF-C3588-M2, AndroidSBC, Colombo

TL;DR: RK3588 Custom Linux BSP

Colombo, Sri Lanka - September 12, 2026. The 181st WF-C3588-M2 shipment left Shenzhen for Colombo this week with 9,205 units aboard, after a full burn-in cycle and a destination-market document check.

AndroidSBC OEM partnership announcement on the custom RK3588 motherboard line serving Colombo, Sri Lanka. The line spans custom Android motherboards at the entry variant through core-board-plus-carrier work at the SOM end, all on the same Rockchip RK3588 silicon with 6 TOPS NPU, 8K H.265 decode and up to 32GB of LPDDR5. AndroidSBC ships the full range from the Wanlin Longgang plant, and Colombo buyers can mix custom variants inside a single framework agreement rather than opening a new supplier file for each product line.

About AndroidSBC and the Rockchip RK3588 Board Family

AndroidSBC is the export brand of Wanlin Manufacturing Group, a Shenzhen source-factory group that has spent more than a decade building custom OEM and ODM boards on Rockchip silicon. The line this release covers is the WF-C3588: nine custom motherboard variants built on the same Rockchip RK3588 octa-core 8nm platform with 6 TOPS NPU and 8K H.265 video, covering custom Android motherboards, custom industrial boards, core board and SOM carrier design, custom signage and video wall boards, custom kiosk and POS boards, custom robotics controllers, custom NVR boards, custom edge AI boards, and custom ARM PC and NAS boards. Wanlin's Longgang plant in Shenzhen builds the WF-C3588 for Sri Lanka OEM, integrator and distributor programmes. For a Colombo buyer the practical value of the line is that one silicon and one supplier file cover nine custom categories.

WF-C3588-M2 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-M2 (Custom Core Board SOM with Carrier Board Design Service) holds its display output and its decoder load at the same time through the burn-in loop, a combination that the legacy boards in the comparison column cannot sustain. For Sri Lanka importers sourcing the WF-Series, the 16GB + 64GB (WF-C3588-M2-C) variant is the typical configuration for the custom core board and SOM plus carrier programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Custom Core Board SOM with Carrier Board Design Service for Sri Lanka Buyers

Buyers in Colombo who have sourced a custom core board som with carrier board design service for a few seasons tend to separate two questions: can the factory hold the price, and can it hold the allocation. The second one is harder. The Rockchip RK3588 is allocated at wafer level, and a 9,205-unit order placed against trader stock is the order most likely to slip a quarter without anyone warning the buyer. The second issue is firmware, not hardware. Vendors promise the full certified software stack and then ship a bare AOSP image, and the failure only surfaces at the warehouse when the unit is powered on against the customer's app.

The third exposure is paperwork. Factories that stamp marks without holding the underlying test reports leave the importer to produce a Technical File after the fact, which is exactly when the container is sitting in a bonded yard. AndroidSBC runs the custom board build, the certified image burn, the burn-in record and the certification file inside the Longgang plant, so the lot arrives complete rather than in pieces. The nine variants in the WF-C3588 cover SMARC 2.2 modules, stamp-hole core boards, LGA core boards, COM Express carriers, medical imaging terminals, robotics compute modules, custom carrier designs, and OEM development kits and each one carries three memory configurations, which keeps Colombo and Sri Lanka buyers on standard custom SKUs for most requirements.

The Sri Lanka paperwork question is settled before production. In Sri Lanka TRCSL approval is required for terminal equipment, and the approval is held locally by the importer. The Longgang export desk prepares the destination-market file covering TRCSL type approval for telecom terminal equipment administered by TRCSL and releases it with the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), booking the lot into Port of Colombo on the Colombo to Shekou lane.

Competitive Comparison: WF-C3588-M2 vs Competing RK3588 Boards

The comparison set for the custom core board som with carrier board design service socket breaks three ways: catalogue boards with fixed I/O and no engineering support, re-badged imports with a sticker but no schematic, and source-factory custom boards that carry the BSP, the test bench and the certification desk in-house. The WF-C3588-M2 is in the last group, and the separation comes from Rockchip RK3588, from customization depth, and from the per-lot certified image burn.

• vs standard SOM catalogues: the WF-C3588-M2 either matches SMARC 2.2 exactly or the carrier is redesigned around the project, so the module never forces the product.
• vs two-vendor module plus carrier splits: core board and carrier come from one desk, one schematic review and one test plan, which removes the finger-pointing stage entirely.
• vs closed-module vendors: BSP source, SDK and documentation ship with the project, so a customer engineering team can maintain the carrier after delivery.
• vs re-branded modules: the SI report and the thermal map are Longgang documents, not forwarded PDFs from a third party.

Global Custom SOM and Core Board Market Trends

The Custom SOM and Core Board market sets the pace for Colombo procurement this year, and it does not move on its own. The Edge AI hardware segment that MarketsandMarkets values at USD 26.9 billion in 2025, with a 32.7 percent CAGR reaching USD 108.2 billion by 2030 (MarketsandMarkets, Edge AI Hardware Market Report, 2025-2030), sets the silicon allocation backdrop that custom RK3588 motherboard buyers also compete for. Three patterns stand out in the WF-C3588 order book for Sri Lanka:

• Medical imaging terminal: a device maker keeps its regulatory file intact by swapping the core board and reusing the validated carrier.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-M2 board carries that headroom without a board change.
• Custom SMARC migration: a legacy SMARC installation moves to RK3588 with a pin-compatible carrier revision and keeps the enclosure.

What the Custom SOM and Core Board data does not show is the operational cost of a supply break, which is why Colombo buyers increasingly weight supplier continuity above a marginal price difference.

Read together, the three patterns explain the move in Colombo from spot quotes to framework agreements released monthly, which is what a custom RK3588 motherboard programme needs to hold a twelve-month shipping window without a mid-year break.

Partner Success Story: Ostra Vision Labs in Colombo, Sri Lanka

Ostra Vision Labs, a machine vision integrator serving the Sri Lanka market, deployed 4,900 custom WF-C3588-E7 edge AI boards for factory inspection lines. The rollout covered the medical imaging terminal, custom smarc migration, and machine vision carrier workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

• Deployed: 4,900 custom WF-C3588-E7 edge AI boards for factory inspection lines
• Region: Colombo, Sri Lanka
• Models used: WF-C3588-M2 (lead SKU), plus eight sibling custom RK3588 board variants in the same platform family
• Certifications handled: CE, FCC, UKCA, RoHS, REACH, IEC 62368-1, EN 55032, EN 55035, plus optional UL 60950-1, GMS, Widevine L1 and Dolby Audio per variant
• Logistics: FOB Shanghai Yangshan with the Wanlin Group Longgang source factory named on the export declaration, entering Port of Colombo via the Colombo to Shekou lane

"Our defect model went from ONNX to RKNN inside a week with their engineering desk, not a forum thread. The boards run four cameras per cell with classification at line speed, and the per-unit barcode makes every RMA a root-cause report instead of a swap."

- Daniel Reyes, VP Product

Field Report: a high-brightness outdoor display trial in Colombo, where 9,205 units of the WF-C3588-M2 board are running behind sunlight-readable panels

Reporter Pan Ze, on the ground in Colombo, Sri Lanka. The trial ran the WF-C3588-M2 boards inside a sealed enclosure with no active cooling and a panel brightness pushed to its ceiling. Internal board temperature stabilised below the throttle point across a full day of direct sun, and the content loop ran without a dropped frame from morning to evening.

A spare-parts kit was packed alongside the order so the destination depot could swap a board without waiting on a cross-border shipment.

The inspection confirmed three things on the spot: the WF-C3588-M2 units hold the burn-in with a yield above 99.18 percent, the loaded firmware image survives a 72-hour continuous loop without credential drift, and the pallets carry the matching certification file for the destination market, covering TRCSL type approval for telecom terminal equipment administered by TRCSL, cleared for entry at Port of Colombo on the Colombo to Shekou lane. Wanlin remains one of the few source factories currently shipping a nine-variant custom RK3588 motherboard line with a per-lot paper trail that Sri Lanka importers can hand straight to their customs broker.

WF-C3588-M2 Application Scenarios

The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-M2 (Custom Core Board SOM with Carrier Board Design Service) as the lead SKU for Colombo and Sri Lanka programmes:

• Medical imaging terminal: a device maker keeps its regulatory file intact by swapping the core board and reusing the validated carrier.
• Robotics compute module: an AMR maker takes the stamp-hole core board and designs a slim carrier for a new chassis generation.
• Custom SMARC migration: a legacy SMARC installation moves to RK3588 with a pin-compatible carrier revision and keeps the enclosure.
• OEM development kit: a product team gets the reference carrier, the SDK and the BSP source and prototypes before committing to tooling.
• LGA core board programme: a display brand solders the core board directly onto its own mainboard for a locked BOM.
• Machine vision carrier: a vision integrator routes MIPI CSI-2 lanes to four cameras and lets the NPU carry the inspection model.
• Fleet compute module: a telematics supplier builds one carrier for three vehicle programmes and swaps memory options per contract.
• Lab instrumentation: an instrument maker keeps a decade-old enclosure alive by replacing only the core board and the BSP.

Partnership Models for Colombo Buyers

Three commercial structures are open to Colombo buyers on the WF-C3588-M2 and the rest of the WF-C3588 custom variants:

• OEM (your brand on our hardware): custom logo silk-print, custom packaging, custom boot animation, custom SKU label, and a private-label certification file.
• ODM (your spec on our reference design): schematic and stack-up review, carrier or motherboard redesign, custom firmware features, and a BSP port handled by the Longgang engineering desk.
• Distribution (your channel, our stock): regional distributor rights, channel rebate, stock holding at the factory, and a framework agreement with a monthly lot release.

The three tiers share one factory, one test flow and one certification file. For Colombo buyers the standard entry point on the WF-C3588-M2 is the 16GB + 64GB (WF-C3588-M2-C) configuration at MOQ 5,000 units per shipment, 1-3 days to sample on standard variants and 15-30 days to mass production.

Frequently Asked Questions

What exactly can be customised on an RK3588 motherboard from AndroidSBC?

Answer: Practically the layers that decide whether the board fits your product: the PCB layout and outline, the memory and storage fit (4GB to 32GB LPDDR4X/LPDDR5, eMMC to 128GB plus NVMe or SATA), the display interface mix (HDMI 2.1, DP 1.4, LVDS/eDP/MIPI), the I/O bank (CAN, RS232/RS485 multi-serial, relays, digital I/O), the wireless stack, and the enclosure or DIN-rail chassis. On top of that sit the firmware options: custom Android ROM with a locked launcher, custom Linux or Yocto image, pre-installed applications, custom boot animation and OTA updates. A Sri Lanka buyer can start from a standard WF-C3588 variant and change one layer, or bring a full schematic and have the carrier designed from scratch.

Can AndroidSBC port a custom Android ROM or a custom Linux BSP to our carrier board?

Answer: Yes. Under NDA, AndroidSBC delivers custom Android ROM work with proprietary services and a locked launcher, custom Linux images on Ubuntu, Debian, Yocto or Buildroot, BSP ports for customer carriers, and driver development for project-specific I/O. Source access is released to the partner, and the port is performed at Longgang, which matters because a vendor BSP rarely matches a custom carrier revision on the first try.

Can the 6 TOPS NPU on a custom board run our own AI models?

Answer: The NPU is fully open on the custom line. Bring the model in PyTorch, ONNX, TensorFlow or Caffe and the Longgang desk handles the RKNN quantization, the runtime integration and the validation against your board's thermal and memory profile. Custom AI algorithm integration is a standard line item on the ODM scope, and the resulting model ships embedded in the firmware image burned per lot.

What are the MOQ and lead times for a custom RK3588 motherboard?

Answer: Standard-variant samples ship in 1-3 days from stock, so your engineering team can start integration while the custom scope is being quoted. A custom run follows a 15-30 day mass-production window after schematic and stack-up sign-off. MOQ is 5,000 units per shipment on standard variants; on custom configurations the MOQ is negotiable against volume commitments, and small batch orders are accepted for pilot phases. A twelve-month framework agreement with monthly lot releases brings the per-lot MOQ down further.

What certifications does a custom board need for Sri Lanka, and who handles them?

Answer: AndroidSBC handles them at the factory. Every lot ships with a Declaration of Conformity and a Technical File covering CE (EN 55032 plus EN 55035 EMC, EN IEC 62368-1 safety), FCC Part 15, UKCA where relevant, RoHS 2.0 and the REACH declaration, all dated within the prior twelve months. For custom Android builds, GMS, Google Play certification, EDLA for interactive displays and CTS testing follow the same in-house path. Where a Sri Lanka market needs an additional national mark, the export desk confirms coverage before the order is confirmed rather than after.

How long will AndroidSBC keep supplying a custom board?

Answer: Seven years minimum supply, patches maintained across the firmware lines, OTA for firmware and NPU model updates. For a Sri Lanka programme running a custom board in the field, that commitment is written into the agreement at signature, which is what separates a source factory from a catalogue reseller.

Can AndroidSBC ship custom boards to Amazon FBA warehouses or 3PL consolidation points?

Answer: Yes, including DDP into Amazon FBA in the US, EU and Japan, plus 3PL consolidation points in Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Cartons are labelled to FBA inbound spec and the declaration names Longgang as the origin. Partners who consolidate in Hong Kong usually take FOB Yantian and handle the last leg themselves.

How does AndroidSBC handle RMA or DOA replacements on custom boards?

Answer: AndroidSBC targets a 0.3 percent DOA rate across the WF-C3588 line, measured over the prior twelve months. On RMA, the partner returns the faulty WF-C3588-M2 unit to Longgang with its burn-in barcode, and a replacement ships within ten business days. Because the burn-in record and the configuration file are attached per unit, the failure analysis normally comes back with a root cause rather than a credit note, which matters when a custom configuration is holding up a production line.
