Query Display Driver Board for Clinic Reception, WF-K3288, AndroidSBC, Colombo

TL;DR: Query Display Driver Board for Clinic Reception

AndroidSBC sourcing desk: touch query board pricing held flat through the current quarter serving Colombo, Sri Lanka. The WF-K3288 self-service query terminal Android motherboard spans the legacy query terminal refresh with hall display and eleven sister models in the WF-K series, all built on the RK3288 quad-core ARM Cortex-A17 1.8GHz SoC with the ARM Mali-T764 GPU, 1080p HDMI plus LVDS, and Android 10 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-K family from the Longgang source factory in Shenzhen to Colombo and Sri Lanka importers who run hospital information points, bank branch lobbies, government service halls, mall directory stations, airport concourses and outdoor query cabinets.

About AndroidSBC and the Self-Service Query Terminal Android Motherboard Family

The self-service query terminal Android motherboard family from AndroidSBC is manufactured end to end by Wanlin Manufacturing Group in Longgang, Shenzhen. Eight silicon tiers and twelve models let Colombo integrators match cost to duty cycle, while the shared firmware baseline keeps field spares interchangeable across Sri Lanka sites. The factory ships to Sri Lanka on a factory-direct basis, with the driver SDK, compliance files and mounting drawings bundled into the same carton as the boards.

WF-K3288 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-K3288 (legacy query terminal refresh with hall display) 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-K family, the WF-K3288-A variant is the typical configuration for the installed-base query terminal refresh use case, with a sustained weekly capacity of 5000 pcs/wk.

Challenges in Sourcing Self-Service Query Terminal Android Motherboards for Sri Lanka Buyers

A Sri Lanka rollout exposes board weaknesses quickly: a query terminal that works in a climate-controlled showroom in Colombo may not survive an unheated entrance lobby or an outdoor transit plaza.

Finally, the arrival path shapes the plan. Hardware destined for Colombo clears through Port of Colombo, so the TRCSL / SLSI paperwork and the TRCSL type approval with SLSI import conformity route used in Sri Lanka need to travel with the carton, not follow it. For Colombo the outcome is a repeatable 38900-unit batch, confirmed on September 22, 2026, with the Colombo - Singapore lane booked ahead so Sri Lanka sites are not waiting on logistics.

Competitive Comparison: WF-K3288 vs Competing Self-Service Query Terminal Android Boards

What separates the WF-K board from competing query boards in Colombo is less the processor row than the peripheral and reliability rows underneath it.

• Platform breadth: twelve models on eight chips (RK3588, RK3568, RK3566, RK3288, RK3399, A133, H618, T527), so {city} integrators can move between tiers without changing driver stack or mounting pattern.
• Bundled integration: touch, printer, scanner, card reader, camera and voice driver SDK ships in the carton; competing query boards sold to {city} usually ship a board only.
• Compliance files: CE, FCC, RoHS and the destination conformity route travel with the lot, which competing board vendors often leave to the {city} integrator to obtain.
• Long-term supply: one fixed BOM per production lot and a seven-year firmware window, against the frequent silicon swaps seen on competing query boards reaching {city}.

Global Self-Service Query Terminal / Information Kiosk Market Trends

Growth in the query terminal segment is being driven by labour economics as much as by technology. In Sri Lanka the legacy query terminal refresh with hall display lets operators cover longer hours with the same headcount, and Colombo projects are typically justified on exactly that basis.

• Volume shift to board-level sourcing: more integrators now buy the motherboard rather than the finished kiosk, which is why the WF-K3288 and WF-K8800 tiers ship in board form with the enclosure left to the local partner.
• Dual-screen becomes the default: hall display plus touch query on one board is replacing two separate devices, and the WF-K8800 and WF-K8801 configurations address that pattern directly.
• Longer service life expectations: operators now plan five to seven years per query terminal, which favours a fixed BOM such as the WF-K8801 over boards that re-spin silicon between lots.

For Colombo integrators the implication is straightforward. Competing on the query terminal itself is difficult; competing on the integration package that reaches Sri Lanka is where margin survives.

Partner Success Story: Albion Query Solutions (council and clinic service partner)

Aan Albion Query Solutions programme in the United Kingdom service segment illustrates how the WF-K family from AndroidSBC supports Colombo integrators on the ground. Albion Query Solutions delivered 38900 query terminals to council and clinic service points.

Albion Query Solutions Operations Director for United Kingdom Service highlighted: Albion Query Solutions required silent touch feedback plus a legible hall display, and the 38900 WF-K boards delivered to Colombo cleared the accessibility review on first submission.

Field Report: installed-base query terminal refresh at a social security service hall

YANTIAN, Shenzhen, September 22, 2026 - Chu Lin, AndroidSBC field desk. Every WF-K3288 unit in the lot was checked against the same mounting drawing, since Sri Lanka retrofit projects re-use existing cabinets. The WF-K3288 self-service query terminal 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-K3288 legacy query terminal refresh with hall display production lot includes the WF-K3288-A variant as the typical configuration, with touch panel, thermal printer and document scanner driver SDK plus staged OTA management bundled into the source-factory shipment. For Sri Lanka integrators, the TRCSL type approval with SLSI import conformity paperwork is bundled.

Filed by Chu Lin, AndroidSBC field desk, YANTIAN, Shenzhen. Sri Lanka integrators typically request CE plus local radio interface notification for self-service query terminal board deployments.

WF-K3288 Application Scenarios

The WF-K3288 legacy query terminal refresh with hall display sits inside a twelve-variant WF-K self-service query terminal Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand. The WF-K3288-A configuration is the typical build for the installed-base query terminal refresh use case, with touch panel and identity peripheral driver SDK plus staged OTA management bundled.

• Hospital and clinic information points: the WF-K3288 drives a touch query station at the entrance while the hall display shows the same information set to waiting visitors in Colombo.
• Bank and financial branch lobbies: touch query plus counter display from one board, with card reader and ID reader integrated for account and product lookups.
• Government service halls: the WF-K5270 runs tax, social security and real estate information lookup, with printing available on the same board.
• Shopping mall directories: the WF-K8800 serves mall directory and wayfinding lookup, with the advertising screen running an independent content loop.
• Airport and train station concourses: high-brightness information query where the WF-K8801 has to stay readable under strong ambient light.
• Retail and pharmacy price or product lookup: compact stations where the WF-K3600 fits a narrow counter without structural work.
• Outdoor and unheated information cabinets: the industrial tier holds the wide temperature window and 7x24 duty cycle for street-level query points.
• Multi-language public information points: on-screen lookup in more than one language from a single board, with voice assistance where the venue requires it.
• Retrofit programmes in Colombo: the same board re-uses the existing enclosure, panel and mounting pattern so an installed estate can be upgraded board by board.

Partnership Models for Colombo Buyers

Three tracks are open to Colombo integrators, and the difference between them is where the Sri Lanka partner wants to add its own value.

• Distribution track: the partner buys the WF-K board against a published price list, keeps its own stock, and AndroidSBC supplies the driver SDK and compliance files with each lot.
• Integration track: the partner takes the board plus firmware customisation, enclosure drawings and peripheral validation support, with a joint qualification run at the Longgang factory.
• Private-label track: the WF-K board ships under the partner brand with customised boot logo, packaging and documentation, on a fixed BOM held for the length of the agreement.

AndroidSBC reviews Colombo track selection annually with each partner, because Sri Lanka market conditions and the partner own capability both move faster than a fixed reseller contract assumes.

Frequently Asked Questions

Does the WF-K self-service query terminal Android motherboard family support a legacy query terminal refresh with hall display?

Answer: Yes. The legacy query terminal refresh with hall display is supported out of the factory image, and AndroidSBC validates it again on the production lot before the Sri Lanka shipment leaves Shenzhen.

What is the real difference between the RK3288 tier and the other silicon tiers in the WF-K family?

Answer: The difference is workload envelope, not compatibility. A board on the RK3288 tier runs the same factory image as the rest of the WF-K family, which keeps spare parts interchangeable across a Sri Lanka estate.

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

Answer: Yes. The conformity pack for Sri Lanka is prepared by the factory, not by the Colombo integrator, which removes the usual delay between arrival and installation.

What are the MOQ and lead time for a first order of the WF-K self-service query terminal family?

Answer: The MOQ for a first WF-K order is deliberately low so Colombo buyers can run a field pilot: sample quantities ship in 1-3 days and a first production lot is typically 15-30 days. Sri Lanka distribution orders scale from there.

Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-K family?

Answer: Yes, and this is one of the most common requests from Colombo integrators. Custom boot behaviour, pre-installed applications, kiosk-mode restrictions and custom Linux images are all handled at the factory for Sri Lanka projects.

How are software updates and long-term support handled on the WF-K family?

Answer: The WF-K family carries a seven-year update commitment, staged OTA delivery and rollback capability, which lets Colombo partners keep Sri Lanka sites on one validated revision.

Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-K family?

Answer: Yes. FBA preparation is handled at the factory for the WF-K family, so Colombo buyers can have boards shipped directly into a Sri Lanka fulfilment centre with the labelling already applied.

How are RMA and DOA replacements handled on the WF-K self-service query terminal family?

Answer: RMA handling on the WF-K family runs against the lot record, so Colombo partners get a traceable answer rather than a generic replacement, and Sri Lanka estates stay on matched firmware.
