Smart Photo Frame Motherboard, WF-RK3568, AndroidSBC, Colombo

TL;DR: Smart Photo Frame Motherboard

Colombo, Sri Lanka - September 10, 2026. A 37,770-unit consignment of WF-RK3568 boards left the Wanlin Longgang source factory for Colombo this week, the 469th production lot released on the Rockchip RK3568 line.

AndroidSBC production statement on Allwinner and Rockchip board output serving Colombo, Sri Lanka. The WF-Series is a nine-board line rather than a single part number, and the shape is deliberate. Allwinner A133, H618, and T527 cover cost-sensitive display, OTT and Android TV, and industrial edge inference; Rockchip RK3588, RK3568, RK3566, and RK3288 cover 8K video wall, industrial edge, machine vision, and POS; WF-A133S and WF-RK3588S are SOM modules for carrier-board projects. A Colombo buyer can hold one supplier file, one documentation format, and one MOQ structure across every tier it sells.

About AndroidSBC and the Rockchip RK3568 Board Family

The WF-Series exists because Sri Lanka buyers kept asking one supplier for two different performance tiers. Wanlin Manufacturing Group answered by putting three Allwinner platforms (A133, H618, T527) and four Rockchip platforms (RK3588, RK3568, RK3566, RK3288) under one part-number scheme, with WF-A133S and WF-RK3588S covering carrier-board projects. The group runs SMT, burn-in, and pre-compliance testing in one Longgang building in Shenzhen, and the export desk holds the certification file rather than passing it back to the importer. For a Colombo distributor that means one vendor file, one document format, and one MOQ structure across the tiers it sells.

WF-RK3568 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-RK3568 (Industrial Edge Computing Board) 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 4GB + 32GB (WF-RK3568-A) variant is the typical configuration for the industrial edge computing use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Industrial Edge Computing Board for Sri Lanka Buyers

What breaks Sri Lanka sourcing plans on the industrial edge computing board line is not price negotiation, it is the second shipment. The Rockchip RK3568 has to be allocated at wafer level, and the brokers quoting fastest are usually the ones with the least control over that allocation. The software side is the second exposure. A board that boots on the bench is not the same as a board that carries the certified stack a Sri Lanka channel will accept, and the difference usually shows up during inbound inspection rather than at the factory gate.

The third issue is documentation. Some factories stamp the CE mark without the Declaration of Conformity and the Technical File behind it, and the container then sits at the port while the importer tries to reconstruct a test report from a supplier who has already been paid. The answer AndroidSBC applies is to move both risks upstream: the certified image is burned at Longgang, the burn-in record is attached per unit, and the Technical File ships with the lot rather than after it. Across the nine WF-Series boards, the coverage runs from industrial edge computing, commercial display controller, industrial HMI, IoT gateway, smart display terminal, machine monitoring, access control, and building automation, so a Sri Lanka buyer can generally find a standard configuration instead of paying for a bespoke one.

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-RK3568 vs Competing RK3568 Boards

The boards competing for the same socket in the industrial edge computing board segment fall into three groups: low-cost legacy SoC boards without a certified software stack, mainstream Cortex-A55 boards with certification but a lower decoder ceiling, and 64-bit boards that carry both but stop short on expansion. The WF-RK3568 sits in the third group and adds three things: Rockchip RK3568, a display path that survives a continuous loop, and the per-lot certified image burn at Longgang.

• vs RK3288 Cortex-A17 boards: the RK3568 Cortex-A55 2.0GHz lifts integer throughput by roughly 2x at lower idle power.
• vs RK3566 boards: the RK3568 adds dual Gigabit Ethernet plus CAN bus for gateway-class builds.
• vs RK3588 boards: the RK3568 keeps a materially lower BOM where 4K@60fps decode is sufficient.
• vs x86 fan-cooled IPC: the RK3568 fanless design removes the only moving part from the enclosure.

Global Industrial Edge Computing and Smart Display Market Trends

The Industrial Edge Computing and Smart Display market sets the pace for Colombo procurement this year, and it does not move on its own. The consumer Android TV Box segment that Global Growth Insights values at USD 12.45 billion in 2025, with a 30.49 percent CAGR reaching USD 178.2 billion by 2035 (Global Growth Insights, Android TV Box Market Report, 2025-2035), sets the silicon allocation backdrop that commercial board buyers also compete for. Three patterns stand out in the WF-Series order book for Sri Lanka:

• Industrial edge computing: WF-RK3568 runs the edge workload on the 1 TOPS NPU with dual Gigabit uplinks.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-RK3568 board carries that headroom without a board change.
• Industrial HMI: WF-RK3568 holds the wide-temperature envelope with the fanless design.

The read across the Industrial Edge Computing and Smart Display channel is that buyers are consolidating suppliers: fewer vendors, wider platform coverage per vendor, and a longer contract behind each order.

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

Partner Success Story: Summit Self-Service in Colombo, Sri Lanka

Summit Self-Service, a parcel locker manufacturer serving the Sri Lanka market, deployed 8,100 units of the WF-A133S SOM module for a custom parcel locker carrier. The rollout covered the industrial edge computing, industrial hmi, and machine monitoring workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

• Deployed: 8,100 units of the WF-A133S SOM module for a custom parcel locker carrier
• Region: Colombo, Sri Lanka
• Models used: WF-A133, WF-H618, WF-T527, WF-RK3588, WF-RK3568, WF-RK3566, WF-RK3288, WF-A133S, WF-RK3588S
• Certifications handled: CE, FCC, UKCA, RoHS, REACH, GMS, Widevine L1, Dolby Audio
• 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

"We designed our own carrier and let AndroidSBC carry the SOM. The 200-pin connector meant we owned the enclosure interface and they owned the DDR routing risk, which is exactly the split we wanted."

- Elise Tremblay, Head of Hardware

Field Report: the aging and EMC pre-compliance bench at the Wanlin Longgang plant, where 37,770 units of the WF-RK3568 board are being screened before the Colombo shipment

Reporter Fang Yu, on the ground in Colombo, Sri Lanka. The bench ran the lot through a 168-hour aging cycle with periodic power cycling, then moved a sample set to the pre-compliance chamber for radiated emissions and ESD strikes. The WF-RK3568 boards cleared the internal limits with margin, and the results went straight into the lot's Technical File.

The plant maintenance log showed no unscheduled stoppage on the Rockchip RK3568 line during the lot, which the production manager attributed to the AOI pass added last quarter.

The inspection confirmed three things on the spot: the WF-RK3568 units hold the burn-in with a yield above 98.94 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-board Allwinner and Rockchip custom line with a per-lot paper trail that Sri Lanka importers can hand straight to their customs broker.

WF-RK3568 Application Scenarios

The WF-Series fits nine application lanes, with the WF-RK3568 (Industrial Edge Computing Board) as the lead SKU for Colombo and Sri Lanka programmes:

• Industrial edge computing: WF-RK3568 runs the edge workload on the 1 TOPS NPU with dual Gigabit uplinks.
• Commercial display controller: WF-RK3568 drives the 4K@60fps panel pair over HDMI 2.0 and eDP.
• Industrial HMI: WF-RK3568 holds the wide-temperature envelope with the fanless design.
• IoT gateway: WF-RK3568 bridges CAN bus and RS485 field devices onto Ethernet.
• Smart display terminal: WF-RK3568 renders the Android 11 UI on the dual display path.
• Machine monitoring: WF-RK3568 timestamps production data against the onboard RTC.
• Access control: WF-RK3568 runs face recognition on the NPU with the MIPI CSI feed.
• Building automation: WF-RK3568 runs 7x24 with hardware watchdog and scheduled restart.

Partnership Models for Colombo Buyers

Three commercial structures are open to Colombo buyers on the WF-RK3568 and the rest of the WF-Series:

• 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.

All three tiers ship from Longgang under one documentation pack covering CE, FCC, UKCA, RoHS, and REACH. A Colombo first order on the WF-RK3568 is normally the 4GB + 32GB (WF-RK3568-A) configuration at MOQ 5,000 units per shipment, four weeks for samples and six weeks for mass production.

Frequently Asked Questions

Does the WF-Series support certified Android TV or Google Mobile Services?

Answer: Yes, on the platforms where that matters. The WF-H618 runs Android 12 (ATV 12) with Google Mobile Services and is ready for Android 14 (ATV 14). AndroidSBC burns the GMS, Widevine L1, and Dolby Audio stack at the Longgang plant on every production lot, so the board ships ready for Netflix, Disney Plus, Amazon Prime Video, HBO Max, Apple TV, and YouTube TV. The commercial and industrial boards in the line use the AOSP image with an optional GMS build for partners who need it.

What is the difference between the nine WF-Series models?

Answer: Nine boards, seven silicon platforms, two of them modules. WF-A133 and WF-H618 and WF-T527 are the Allwinner entries for commercial display, OTT TV, and industrial edge respectively. WF-RK3588, WF-RK3568, WF-RK3566, and WF-RK3288 are the Rockchip entries for 8K video wall, industrial edge, machine vision, and POS. WF-A133S and WF-RK3588S are board-to-board SOM modules sized for customers who want to design the carrier themselves. Each board carries three memory configurations.

Can AndroidSBC handle CE, FCC, UKCA, RoHS, and REACH paperwork for Sri Lanka?

Answer: That is handled in-house. Each lot leaves Longgang with a Declaration of Conformity and a Technical File holding the CE, FCC Part 15, UKCA, RoHS 2.0, and REACH documents, all dated inside twelve months. For Sri Lanka specifically, AndroidSBC will confirm at quotation stage which marks apply and whether a local variation is required, so the paperwork question is settled before production rather than at the port.

What are the MOQ and lead time for a first order?

Answer: The entry point is 5,000 units per shipment, four weeks for samples and six weeks for production. A twelve-month framework agreement released monthly will bring the per-lot MOQ down, and AndroidSBC will accept a mixed order that draws several WF-Series boards against a single contract.

Does AndroidSBC support custom Android ROM or custom Linux development?

Answer: Yes, under NDA. ODM partners get custom Android ROM work including proprietary services and a custom launcher, Linux builds based on Yocto, Debian, or Buildroot, and BSP ports for custom carrier boards. The SDK and BSP source are released to the partner under the NDA, and AndroidSBC's engineering desk handles the port rather than handing over an unmodified vendor drop.

What about software updates and long-term support?

Answer: Seven years minimum supply, with security patches maintained across the Android and Linux firmware lines. Partners who deploy at scale can use the AndroidSBC OTA infrastructure to update field units. For long-lifecycle programmes in POS, signage, or industrial control, the support term is written into the framework agreement at signature.

Can AndroidSBC ship 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, and Los Angeles. 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?

Answer: AndroidSBC targets a 0.3 percent DOA rate across the WF-Series, measured over the prior twelve months. On RMA, the partner returns the faulty WF-RK3568 unit to Longgang with its burn-in barcode, and a replacement ships within ten business days. Because the burn-in record is attached per unit, the failure analysis normally comes back with a root cause rather than a credit note.
