Government Query Terminal Kiosk Board for Hospital Information Point, WF-K3288, AndroidSBC, Sao Paul
TL;DR: Government Query Terminal Kiosk Board for Hospital Information Point
AndroidSBC supply desk: LPDDR4X and eMMC allocations locked for the WF-K query board family serving Sao Paulo, Brazil. 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 Sao Paulo and Brazil 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 builds boards and nothing else, which is why the WF-K query terminal line is sold factory direct through AndroidSBC. Twelve models cover hospital, bank, government, retail, transport and outdoor query duty, and each one leaves the Longgang line in Shenzhen with the same peripheral driver bundle for Sao Paulo integrators. The factory ships to Brazil on a factory-direct basis, with the driver SDK, compliance files and mounting drawings bundled into the same carton as the 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 Brazil 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 Brazil Buyers
Sourcing a self-service query terminal board for Brazil is not only a chip question. A Sao Paulo integrator has to align the touch stack, the printer and scanner drivers, the enclosure cut-outs and the compliance file set before a single unit reaches the field.
Compliance and logistics compound each other. Boards for Sao Paulo move through Port of Santos, and any mismatch between the ANATEL documents and the ANATEL homologation with INMETRO safety conformity route applied in Brazil surfaces at exactly the wrong moment. AndroidSBC answers this with a single BOM per lot, so a Sao Paulo order of 137300 units carries the same silicon and firmware as the pilot batch for Brazil.
Competitive Comparison: WF-K3288 vs Competing Self-Service Query Terminal Android Boards
The table below puts the WF-K self-service query terminal board against what a Sao Paulo integrator typically finds on competing query boards sold into Brazil.
- 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 Brazil the legacy query terminal refresh with hall display lets operators cover longer hours with the same headcount, and Sao Paulo 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 Brazil buyers, the market shift means the query terminal decision is now a multi-year supply decision, and Sao Paulo projects are increasingly evaluated on that basis.

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 Sao Paulo.
- 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 Sao Paulo: 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 Sao Paulo Buyers
The commercial menu for Sao Paulo integrators has three entries, and Brazil partners usually start on one before adding the others as volumes grow.
- 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 Brazil partners start on the distribution track, add the integration track once volumes justify it, and move to private label when Sao Paulo brand recognition matters more than margin per unit.
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. 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?
