TL;DR: 21.5-Inch Guide All-In-One Board for Information Point
AndroidSBC sourcing desk: smart guide kiosk board pricing held flat through the current quarter serving Colombo, Sri Lanka. The WF-G3288 smart guide kiosk Android motherboard spans the retail guide kiosk and eleven sister models in the WF-G series, all built on the RK3288 quad-core ARM Cortex-A17 1.8GHz 32-bit SoC with the ARM Mali-T764 GPU, HDMI 1.4 1080p plus LVDS, and Android 10 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-G family from the Longgang source factory in Shenzhen to Colombo and Sri Lanka importers who run mall directory, wayfinding, information point, dual-screen promotion, interactive display and outdoor smart city programmes.

About AndroidSBC and the Smart Guide Kiosk Android Motherboard Family
The WF-G smart guide kiosk Android motherboard family spans venue types rather than a single product category. AndroidSBC supplies the same twelve-model family into shopping centre floor directories, tenant and product finders, supermarket price check points, pharmacy enquiry counters, airport and transit wayfinding banks, hospital and clinic orientation points, hotel and resort lobby guides, museum and exhibition interpretive displays, campus and university directories, government building service points, casino and stadium concourse guides and outdoor smart city information pillars. Colombo integrators typically start with one venue type, prove the content stack, then reuse the board on the next site. Sri Lanka distributors buy the family as a catalogue and configure per client instead of re-qualifying a new board for every tender. For Sri Lanka importers the working rhythm in Colombo is a sample lot in 1-3 days, an OEM pilot from 100 pieces and a 15-30 day mass-production window once the BOM is signed off.
WF-G3288 Technical Specifications
| Parameter | AndroidSBC WF-G3288 (retail guide kiosk) | Industry Average |
|---|---|---|
| Processor | RK3288 quad-core ARM Cortex-A17 1.8GHz 32-bit SoC | Older 28nm or 40nm quad-core SoC |
| Process node | 28nm | Older 28nm or 40nm process |
| GPU | Mali-T764 | Older Mali-450 or basic GPU |
| NPU / AI | no NPU, CPU-only inference | No NPU on competing entry boards |
| Memory | 2GB LPDDR3 | DDR3 1GB / 2GB on competing boards |
| Storage | 16GB eMMC | eMMC 5.0 8GB / 16GB on competing boards |
| Display output | HDMI 1.4 1080p plus LVDS | Single HDMI 1080p only on competing boards |
| Touch support | 10-point capacitive touch | Resistive single-touch on competing boards |
| Operating system | Android 10 | Android 8 or Android 9 on competing boards |
| Connectivity | WiFi 5 plus Bluetooth 5.0 plus Gigabit Ethernet | WiFi 4 plus 10/100M Ethernet on competing boards |
| Payment peripherals | QR code scanner, NFC, barcode scanner, thermal printer, cash drawer | No bundled payment-peripheral driver SDK on competing boards |
| Operating temperature | 0C to 50C | 0C to 40C on competing boards |
All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-G3288 (retail guide kiosk) maintains its 4K HDMI output plus capacitive touch sampling while running the burn-in test loop, a configuration that competing single-platform boards cannot sustain at 60fps. For Sri Lanka importers sourcing the WF-G family, the WF-G3288-A variant is the typical configuration for the legacy retail estate guide terminal refresh use case, with a sustained weekly capacity of 5000 pcs/wk.
Challenges in Sourcing Smart Guide Kiosk Android Motherboards for Sri Lanka Buyers
The fourth obstacle is unattended reliability. A directory screen that runs from mall open to mall close, seven days a week, exposes thermal, power and storage weaknesses that a bench test in Colombo will never show.
Working with the source factory removes the middle layer. Sri Lanka integrators reach the AndroidSBC engineering desk directly, Colombo specification changes go into the next layout revision instead of into a negotiation, and failure analysis for any WF-G lot is completed by the TRCSL type approval with SLSI import conformity line that produced it, with TRCSL / SLSI conformity files on record for Port of Colombo. As of September 18, 2026, 38400 boards are allocated to Colombo and Sri Lanka, the 3rd allocation this cycle, moving on the Colombo - Singapore lane.
Competitive Comparison: WF-G3288 vs Competing Smart Guide Kiosk Android Boards
AndroidSBC positions the WF-G family on breadth rather than on a single benchmark number: eight silicon options, twelve models, one driver package and one update channel. That framing is what Colombo and Sri Lanka procurement teams compare against a two-tier competitor line-up.
- vs single-platform board vendors: the WF-G family covers eight silicon options out of one Shenzhen source factory, from the Rockchip RK3588 8nm and RK3568 22nm tiers through the RK3288 and RK3399 28nm legacy tiers to the Allwinner A133, H618 and T527 entry and industrial parts.
- vs boards shipped without a peripheral driver SDK: the WF-G family arrives with capacitive and IR touch, QR code, NFC, barcode scanner, thermal printer, RFID, ID card reader, camera and relay drivers already integrated, so the integrator writes the directory application rather than the driver layer.
- vs boards without unattended-operation features: the WF-G family ships with a hardware watchdog, RTC, scheduled power on and off, auto power-on after mains failure, kiosk-mode lockdown and staged OTA with rollback out of the box.
- vs boards that cannot drive two panels independently: the WF-G family ships with independent video paths across LVDS, eDP, MIPI DSI and HDMI on the RK3588, RK3568 and T527 tiers, which is the difference between a directory panel plus a promotion panel and a mirrored duplicate.
Global Smart Guide Kiosk / Wayfinding / Interactive Display Market Trends
The outdoor and semi-outdoor slice is the fastest-moving part of the guide kiosk category. Smart city programmes across Sri Lanka are specifying information pillars for street level, transit interchanges and park entrances, and the constraint has moved from the touch panel to the board that has to run the directory, the network uplink and the thermal budget at once. Colombo integrators are specifying the retail guide kiosk tier against that reality rather than against an indoor datasheet.
- Mall floor directories and tenant finders: WF-G3288 is the usual starting point for shopping centre rollouts, with the dual-screen WF-G8800 as the directory plus promotion option.
- Transit, hospital and campus wayfinding banks: the mid-tier WF-G8800 and the industrial WF-G8801 sister SKUs form the public venue ladder, with route planning and multi-language content.
- Promotional walls and in-venue signage networks: WF-G8801 and the entry-tier sister SKUs cover continuous-play directory and campaign screens across a venue estate.
These figures are used by AndroidSBC as a demand baseline for Sri Lanka planning, not as a projection for any single Colombo programme.
Partner Success Story: Albion Venue Guides (hospitality and heritage venue supplier)
Aan Albion Venue Guides programme in the UK hospitality and heritage segment illustrates how the WF-G family from AndroidSBC supports Colombo integrators on the ground. Albion Venue Guides installed 38400 WF-G lobby and exhibit guide boards across hotel groups and heritage attractions.
- OEM relationship: AndroidSBC private-label SKU shipped with Albion Venue Guides branding and CE / FCC / RoHS files bundled.
- Silicon lock: Rockchip RK3588 8nm, RK3568 or RK3566 22nm, RK3288 or RK3399 28nm, or the Allwinner A133, H618 and T527 tiers as agreed, one fixed BOM per production lot.
- Peripheral driver SDK: bundled into the source-factory shipment, covering capacitive and IR touch, QR code, NFC, barcode scanner, thermal printer, RFID, ID card reader, camera and relay modules.
- Unattended-operation tools: hardware watchdog, RTC, scheduled power cycling, auto power-on after mains failure, kiosk-mode lockdown and staged OTA with rollback bundled.
- Compliance paperwork: CE / FCC / RoHS plus TRCSL / SLSI conformity, all bundled into the Shenzhen source-factory shipment.
Albion Venue Guides Visitor Systems Lead for UK Hospitality and Heritage highlighted: Albion Venue Guides runs heritage sites where the enclosure cannot be modified, and the compact WF-G layout let 38400 existing housings in Colombo take a new board without a mechanical redesign.
Field Report: legacy estate refresh at a supermarket group
YANTIAN, Shenzhen, September 18, 2026 - Deng Hui, AndroidSBC field desk. A mains-cut test was run mid-burn-in: power was removed for 30 seconds and the WF-G3288 boards returned to the retail guide kiosk directory home screen without operator input. The WF-G3288 smart guide kiosk Android motherboard order for Colombo, Sri Lanka cleared the burn-in station on schedule and is en route via the Colombo - Singapore lane.
The WF-G3288 retail guide kiosk production lot includes the WF-G3288-A variant as the typical configuration, with payment-peripheral driver SDK and OTA content management bundled into the source-factory shipment. For Sri Lanka integrators, the TRCSL / SLSI conformity plus TRCSL type approval with SLSI import conformity paperwork is bundled.

Partnership Models for Colombo Buyers
Three partnership models are open on the WF-G smart guide kiosk Android motherboard family for Colombo and Sri Lanka, and they differ in how much of the design the partner owns.
- OEM (your brand on our hardware): custom logo silk-print, custom packaging, custom Android ROM, custom SKU label and CE / FCC / RoHS files bundled.
- ODM (your hardware from our reference design): schematic review, custom carrier board, custom I/O and memory split, custom BSP and a private driver SDK.
- Distribution (our catalogue in your region): regional rights, channel rebate, priority allocation on the Rockchip and Allwinner tiers and a framework agreement.
One production line in Longgang serves all three tracks, so a Colombo partner who starts on the distribution track and later commissions an ODM design stays on the same Sri Lanka supply chain.
Frequently Asked Questions
Does the WF-G smart guide kiosk Android motherboard family support a retail guide kiosk?
Answer: Yes. AndroidSBC ships the WF-G family with retail guide kiosk as a standard configuration; the Rockchip and Allwinner tiers share one firmware baseline, one driver package and one update channel.
What is the real difference between the RK3288 tier and the other silicon tiers in the WF-G family?
Answer: The differences are measurable. RK3588 is 8nm with eight cores, Mali-G610 MP4 and 6 TOPS; RK3568 is 22nm, quad-core A55 2.0GHz, Mali-G52 2EE, 1 TOPS and triple independent output; RK3566 is the same core at 1.8GHz with 0.8 TOPS; RK3288 is a 28nm 32-bit A17 part with the Mali-T764; RK3399 is a 28nm big.LITTLE A72 plus A53 part with the Mali-T860 MP4; T527 is a 22nm octa-core A55 industrial part with 2 TOPS; A133 and H618 are quad-core A53 entry parts. AndroidSBC specifies RK3288 against the workload for Colombo.
Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for Sri Lanka?
Answer: Yes. For Sri Lanka buyers the standard bundle is CE / FCC / RoHS plus TRCSL / SLSI conformity and TRCSL type approval with SLSI import conformity, routed through Port of Colombo. AndroidSBC also keeps the EMC, ESD and surge immunity test reports on file for venue property handover in Colombo.
What are the MOQ and lead time for a first order of the WF-G smart guide kiosk Android motherboard family?
Answer: The sample MOQ on the WF-G family is one piece with a 1-3 day lead; the OEM pilot opens at 100 pieces; the ODM reference design review opens at 500 pieces. Mass production runs on a 15-30 day lead once the BOM is signed off.
Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-G family?
Answer: Yes. The ODM track covers AOSP and Linux BSP porting, custom boot animation, custom launcher, pre-installed content clients and driver work. Colombo integrators get a versioned build they can pin rather than a vendor image that changes without notice.
How are software updates and long-term support handled on the WF-G family?
Answer: AndroidSBC handles updates as a supply commitment: a seven-year firmware window, a versioned SDK, staged OTA with rollback, and a documented migration path when a silicon tier reaches end of life. For Colombo estates that removes the usual two-year requalification cycle.
Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-G family?
Answer: Yes. Shipments can be consolidated into a 3PL or FBA destination for Colombo partners, with carton labelling, palletisation and the TRCSL / SLSI plus TRCSL type approval with SLSI import conformity paperwork prepared in Shenzhen before the lot leaves.
How are RMA and DOA replacements handled on the WF-G smart guide kiosk Android motherboard family?
Answer: AndroidSBC runs RMA from the factory, not from a distributor. DOA is replaced on evidence from buffer stock, field failures are analysed by the line that built the board, and the report goes back to the Sri Lanka integrator with the root cause.
