TL;DR: Dual-screen Mirrored Display Query Terminal Board
AndroidSBC sourcing desk: touch query board pricing held flat through the current quarter serving international market, United States. 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 international market and United States importers who run hospital information points, bank branch lobbies, government service halls, mall directory stations, airport concourses and outdoor query cabinets.
WF-K3288 Technical Specifications
| Parameter | AndroidSBC WF-K3288 (legacy query terminal refresh with hall display) | Industry Average |
|---|---|---|
| Processor | RK3288 quad-core ARM Cortex-A17 1.8GHz 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 | none | No NPU on competing entry boards |
| Memory | 2GB DDR3 | DDR3 1GB / 2GB on competing boards |
| Storage | 16GB eMMC | eMMC 5.0 8GB / 16GB on competing boards |
| Display output | 1080p HDMI 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 |
| Query peripherals | Capacitive touch, thermal printer, document scanner, card reader | No bundled touch, printer or scanner 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-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 United States 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 United States Buyers
Buyers in international market often treat a self-service query terminal as a commodity board, then discover that the printer driver, the card reader stack and the kiosk-mode lockdown each need separate validation against United States deployment conditions.
Add the compliance layer and the picture gets tighter. For United States the paperwork runs through FCC Part 15 and FCC ID for radio modules, plus UL or ETL safety listing, and a board that was never validated against it turns into a re-test cycle that international market integrators pay for in schedule, not just money. The factory answers with lot-level BOM control, so the international market order of 23900 units is the 3rd in a series that never re-qualifies the peripheral stack.
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 international market.
- 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-K3600 runs tax, social security and real estate information lookup, with printing available on the same board.
- Shopping mall directories: the WF-K3601 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-K3602 has to stay readable under strong ambient light.
- Retail and pharmacy price or product lookup: compact stations where the WF-K3566 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 international market: 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 international market Buyers
Three tracks are open to international market integrators, and the difference between them is where the United States 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.
In practice United States partners start on the distribution track, add the integration track once volumes justify it, and move to private label when international market brand recognition matters more than margin per unit.
Does the WF-K self-service query terminal Android motherboard family support a legacy query terminal refresh with hall display?
Answer: Yes. AndroidSBC treats the legacy query terminal refresh with hall display as a stock case on the WF-K family and validates it on every tier that could plausibly run it, including the entry and industrial parts.
What is the real difference between the RK3288 tier and the other silicon tiers in the WF-K family?
Answer: The RK3288 tier carries its own process node, GPU and NPU rating, and AndroidSBC publishes all three per model so international market integrators can compare on facts rather than on marketing labels.
Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for United States?
Answer: Yes. AndroidSBC handles the compliance route for United States directly, and international market buyers receive the certificate set with the shipping documents so customs clearance is not held on paperwork.
What are the MOQ and lead time for a first order of the WF-K self-service query terminal family?
Answer: MOQ is quoted per model rather than per family, so a international market integrator can pilot one tier for United States without buying across all twelve. Samples take 1-3 days and bulk lots 15-30 days.
Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-K family?
Answer: Yes. AndroidSBC develops custom Android ROM and custom Linux builds for the WF-K family, with the work scoped against the international market requirement and validated on the same production rig that ships United States orders.
How are software updates and long-term support handled on the WF-K family?
Answer: Updates are delivered through a staged OTA channel with rollback support, and international market integrators decide when a United States estate moves to a new build rather than being pushed onto it.
Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-K family?
Answer: Yes, and where a international market seller runs its own 3PL arrangement in United States, AndroidSBC ships to that warehouse on the same terms as a direct buyer order.
How are RMA and DOA replacements handled on the WF-K self-service query terminal family?
Answer: DOA units are replaced from the next available lot, and RMA cases are tracked by lot number. For international market integrators this keeps United States deployments serviceable without holding large local stock.
