Query Terminal Microphone Board, WF-K3566
TL;DR: Query Terminal Microphone Board
AndroidSBC software desk: Android 15 baseline and staged OTA channel published for the WF-K family serving international market, United States. The WF-K3566 self-service query terminal Android motherboard spans the compact self-service query terminal and eleven sister models in the WF-K series, all built on the RK3566 quad-core ARM Cortex-A55 1.8GHz 64-bit SoC with the ARM Mali-G52 2EE GPU, single 1080p output plus LVDS, 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 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.

About AndroidSBC and the Self-Service Query Terminal Android Motherboard Family
AndroidSBC manufactures the WF-K self-service query terminal Android motherboard family at the Wanlin Manufacturing Group plant in Longgang, Shenzhen. For United States buyers the series is deliberately broad: entry A133 boards for simple lookup stations, RK3568 workhorses for dual-screen work, and RK3588 parts where international market projects need 8K or AI acceleration. Every model is validated on the same burn-in rig in Longgang before it is packed for United States, and the same rig logs are available on request.
WF-K3566 Technical Specifications

| Process node | 22nm | Older 28nm or 40nm process |
| GPU | Mali-G52 2EE | Older Mali-450 or basic GPU |
| NPU / AI | 0.8 TOPS | No NPU on competing entry boards |
| Memory | 2GB LPDDR4 | DDR3 1GB / 2GB on competing boards |
| Storage | 16GB eMMC | eMMC 5.0 8GB / 16GB on competing boards |
| Display output | single 1080p output plus LVDS | Single HDMI 1080p only on competing boards |
| Touch support | 10-point capacitive touch | Resistive single-touch on competing boards |
| Operating system | Android 11 | 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-K3566 (compact self-service query terminal) 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-K3566-A variant is the typical configuration for the compact clinic and pharmacy query rollout use case, with a sustained weekly capacity of 5000 pcs/wk.
Challenges in Sourcing Self-Service Query Terminal Android Motherboards for United States Buyers
Procurement teams in United States usually compare query terminal boards on price first, then find that integrating three vendors for touch, printing and identity peripherals costs more than the difference between a cheap board and the right one for international market.
Compliance is the second filter. international market buyers need a board whose FCC / UL file set matches the FCC Part 15 and FCC ID for radio modules, plus UL or ETL safety listing route used in United States, which is the point where unbranded board suppliers usually drop out. For the 7th consecutive quarter, AndroidSBC has held the international market allocation against one fixed BOM, which is why a 72100-unit programme can be dated rather than estimated.
Competitive Comparison: WF-K3566 vs Competing Self-Service Query Terminal Android Boards
Competing query boards in United States often win on headline price until the international market integrator prices in the missing driver SDK and compliance files.
- 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 United States that shows up as bundled tenders covering the compact self-service query terminal together with hall displays and information screens, and international market 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-K3566 and WF-K1331 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-K1331 and WF-K6180 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-K6180 over boards that re-spin silicon between lots.
For international market the practical reading is that query terminal demand is not a spike but a standing requirement, and United States operators are buying on repeatability rather than on a one-off price.
WF-K3566 Application Scenarios
The WF-K3566 compact self-service query terminal sits inside a twelve-variant WF-K self-service query terminal Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand. The WF-K3566-A configuration is the typical build for the compact clinic and pharmacy query rollout use case, with touch panel and identity peripheral driver SDK plus staged OTA management bundled.
- Hospital and clinic information points: the WF-K3566 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-K1330 runs tax, social security and real estate information lookup, with printing available on the same board.
- Shopping mall directories: the WF-K1331 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-K6180 has to stay readable under strong ambient light.
- Retail and pharmacy price or product lookup: compact stations where the WF-K5270 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
AndroidSBC works with international market integrators on three commercial tracks rather than one, because United States 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 United States buyers the sequencing advice is simple: prove the board on one pilot site in international market, then choose the track that matches the volume the pilot generates.
Frequently Asked Questions
Does the WF-K self-service query terminal Android motherboard family support a compact self-service query terminal?
Answer: Yes. The compact self-service query terminal is covered by the standard WF-K driver SDK, which means the international market integrator configures it rather than ports it.
What is the real difference between the RK3566 tier and the other silicon tiers in the WF-K family?
Answer: Practically, the RK3566 tier is chosen when the United States use case matches its video and AI envelope. The interface contract is identical across the family, so the decision is about workload rather than about connectors or drivers.
Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for United States?
Answer: Yes, and the paperwork is treated as part of the product rather than an add-on. For United States orders the CE, FCC, RoHS and REACH set is prepared alongside the production lot bound for international market.
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 handles AOSP customisation, kiosk-mode lockdown and Linux images for the WF-K family, with the resulting build validated on the same rig used for United States shipments to international market.
How are software updates and long-term support handled on the WF-K family?
Answer: AndroidSBC maintains a seven-year firmware window on the WF-K family, with staged OTA and rollback. international market partners can freeze a revision per United States project and update on their own schedule.
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: AndroidSBC handles RMA and DOA replacements per production lot, which means a international market partner can trace a failure back to a specific build shipped to United States rather than dealing with an anonymous board.
