TL;DR: Query Terminal LVDS Output Board for Hospital Information Point
AndroidSBC sourcing desk: touch query board pricing held flat through the current quarter serving Malaga, Spain. The WF-K3399 self-service query terminal Android motherboard spans the dual-screen HD query terminal with mirrored display and eleven sister models in the WF-K series, all built on the RK3399 dual Cortex-A72 1.8GHz plus quad Cortex-A53 SoC with the ARM Mali-T860 MP4 GPU, dual 1080p output, HDMI plus eDP, and Android 11 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-K family from the Longgang source factory in Shenzhen to Malaga and Spain 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
Wanlin Manufacturing Group has supplied board-level hardware to overseas integrators for years, and the WF-K self-service query terminal line is its dedicated query answer. Twelve models, eight platforms, one Longgang production base in Shenzhen, and a single peripheral driver SDK that Malaga teams flash once and reuse across projects. Every model is validated on the same burn-in rig in Longgang before it is packed for Spain, and the same rig logs are available on request.

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-K3399 (dual-screen HD query terminal with mirrored 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 Spain importers sourcing the WF-K family, the WF-K3399-A variant is the typical configuration for the dual-screen HD mall directory rollout use case, with a sustained weekly capacity of 5000 pcs/wk.
Challenges in Sourcing Self-Service Query Terminal Android Motherboards for Spain Buyers
Buyers in Malaga 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 Spain deployment conditions.
Add the compliance layer and the picture gets tighter. For Spain the paperwork runs through CE marking with CNMC radio interface notification, and a board that was never validated against it turns into a re-test cycle that Malaga integrators pay for in schedule, not just money. The factory answers with lot-level BOM control, so the Malaga order of 34000 units is the 4th in a series that never re-qualifies the peripheral stack.
Competitive Comparison: WF-K3399 vs Competing Self-Service Query Terminal Android Boards
A Malaga buyer comparing query boards for Spain should read the last three rows first: peripherals, temperature range and what is bundled, not billed separately.
- 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
The query terminal category is expanding faster than the general kiosk market because it replaces a staffed desk rather than supplementing one. In Spain that shows up as bundled tenders covering the dual-screen HD query terminal with mirrored display together with hall displays and information screens, and Malaga operators are following the same pattern.
- Volume shift to board-level sourcing: more integrators now buy the motherboard rather than the finished kiosk, which is why the WF-K3399 and WF-K5270 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-K5270 and WF-K8800 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-K8800 over boards that re-spin silicon between lots.
For Malaga the practical reading is that query terminal demand is not a spike but a standing requirement, and Spain operators are buying on repeatability rather than on a one-off price.
Partner Success Story: Siam InfoTerm Holdings (hospital group technology supplier)

WF-K3399 Application Scenarios
The WF-K3399 dual-screen HD query terminal with mirrored 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-K3399-A configuration is the typical build for the dual-screen HD mall directory rollout use case, with touch panel and identity peripheral driver SDK plus staged OTA management bundled.
- Hospital and clinic information points: the WF-K3399 drives a touch query station at the entrance while the hall display shows the same information set to waiting visitors in Malaga.
- 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-K8801 runs tax, social security and real estate information lookup, with printing available on the same board.
- Shopping mall directories: the WF-K3600 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-K3601 has to stay readable under strong ambient light.
- Retail and pharmacy price or product lookup: compact stations where the WF-K3602 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 Malaga: 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 Malaga Buyers
AndroidSBC works with Malaga integrators on three commercial tracks rather than one, because Spain projects differ in how much of the stack the local partner wants to own.
- 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.
For a first Spain order, Malaga integrators typically begin on the distribution track with a single model, then widen to the full twelve-model WF-K range once field data is in hand.
Frequently Asked Questions
Does the WF-K self-service query terminal Android motherboard family support a dual-screen HD query terminal with mirrored display?
Answer: Yes. AndroidSBC treats the dual-screen HD query terminal with mirrored 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 RK3399 tier and the other silicon tiers in the WF-K family?
Answer: The RK3399 tier carries its own process node, GPU and NPU rating, and AndroidSBC publishes all three per model so Malaga integrators can compare on facts rather than on marketing labels.
Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for Spain?
Answer: Yes. AndroidSBC handles the compliance route for Spain directly, and Malaga 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 Malaga integrator can pilot one tier for Spain 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 Malaga requirement and validated on the same production rig that ships Spain 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 Malaga integrators decide when a Spain 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 Malaga seller runs its own 3PL arrangement in Spain, 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 Malaga integrators this keeps Spain deployments serviceable without holding large local stock.
