TL;DR: M.2 Expansion Query Terminal Board for Clinic Reception
AndroidSBC peripheral desk: printer, scanner and card reader driver SDK declared production-ready serving Gothenburg, Sweden. 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 Gothenburg and Sweden 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 Gothenburg integrators match cost to duty cycle, while the shared firmware baseline keeps field spares interchangeable across Sweden sites. Purchasing runs through the Shenzhen export desk, so Gothenburg buyers deal with the manufacturing entity rather than a trading layer.

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 Sweden 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 Sweden Buyers
Sourcing a self-service query terminal board for Sweden is not only a chip question. A Gothenburg 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.
Finally, the arrival path shapes the plan. Hardware destined for Gothenburg clears through Port of Stockholm, so the PTS paperwork and the CE marking with PTS radio interface notification route used in Sweden need to travel with the carton, not follow it. For Sweden buyers the effect is that a 63100-unit order for Gothenburg repeats identically the 1st time it is placed, down to the firmware revision.
Competitive Comparison: WF-K3288 vs Competing Self-Service Query Terminal Android Boards
What separates the WF-K board from competing query boards in Gothenburg 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
Self-service query terminals are moving from a specialist niche into standard public infrastructure, and Sweden is part of that shift. Demand for the legacy query terminal refresh with hall display is being pulled by service halls that want to shorten front-desk queues and by operators in Gothenburg who need the same answer available outside staffed hours.
- 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-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 Gothenburg the opportunity sits in service coverage: operators in Sweden are adding information points faster than they are adding staff, and that gap is what the query terminal fills.
Partner Success Story: Siam InfoTerm Holdings (hospital group technology supplier)
A Siam InfoTerm Holdings rollout in the Southeast Asia healthcare segment shows how the WF-K self-service query terminal family works in practice for Gothenburg integrators. Siam InfoTerm Holdings supplied 63100 query boards to hospital outpatient information desks.
- OEM relationship: AndroidSBC private-label SKU shipped with Siam InfoTerm Holdings branding and CE / FCC / RoHS files bundled.
- Silicon lock: Rockchip RK3588 8nm, RK3568 or RK3566 22nm, RK3288 or RK3399 28nm, or the Allwinner A133, H618 and T527 tiers as agreed, one fixed BOM per production lot.
- Peripheral driver SDK: bundled into the source-factory shipment, covering capacitive touch, thermal printer, receipt printer, document scanner, A4 printer, barcode scanner, QR code, NFC, RFID, card reader, ID reader, face recognition, voice module, speaker amplifier and microphone.
- Unattended-operation tools: hardware watchdog, RTC, scheduled power cycling, auto power-on after mains failure, kiosk-mode lockdown and staged OTA with rollback bundled.
- Compliance paperwork: CE / FCC / RoHS plus PTS conformity, all bundled into the Shenzhen source-factory shipment.
As Siam InfoTerm Holdings Managing Director for Southeast Asia Healthcare put it: Siam InfoTerm Holdings rolled the WF-K single-screen board into outpatient information desks, and the 63100 units delivered to Gothenburg came with the printer and card reader drivers already integrated.
Field Report: installed-base query terminal refresh at a social security service hall

Filed by Huan Xi, AndroidSBC field desk, NANSHAN, Shenzhen. Sweden 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 Gothenburg.
- 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 Gothenburg: 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 Gothenburg Buyers
Three partnership tracks serve the Sweden market, and Gothenburg integrators can move between them as their own capability and volume change.
- 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 Gothenburg track selection annually with each partner, because Sweden 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. AndroidSBC ships the legacy query terminal refresh with hall display as a standard configuration, and the touch, printer and card reader drivers for it are integrated into the factory image rather than added by the Gothenburg integrator on site.
What is the real difference between the RK3288 tier and the other silicon tiers in the WF-K family?
Answer: The RK3288 tier differs in compute headroom, display capability and NPU availability rather than in board-level interfaces. All WF-K models share the same mounting pattern, the same peripheral pinout and the same firmware baseline, so a Sweden project can move between tiers without re-designing the enclosure.
Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for Sweden?
Answer: Yes. AndroidSBC prepares the conformity file set for Sweden as part of the order, covering CE, FCC, RoHS and REACH as applicable, plus the destination-specific route. The documents travel with the Gothenburg shipment rather than following it.
What are the MOQ and lead time for a first order of the WF-K self-service query terminal family?
Answer: AndroidSBC sets a pilot-friendly MOQ on the WF-K family. Sample units reach Gothenburg in 1-3 days, and a first bulk lot for Sweden runs 15-30 days from confirmation.
Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-K family?
Answer: Yes, and the custom build is maintained as a branch rather than a one-off, so Gothenburg partners receive updates against their own image for as long as the Sweden programme runs.
How are software updates and long-term support handled on the WF-K family?
Answer: AndroidSBC supports field updates by staged OTA with rollback, plus local update packages where a Gothenburg integrator needs to service Sweden sites without network access.
Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-K family?
Answer: Yes, and this is a standard route for Gothenburg sellers. AndroidSBC prepares FBA-compliant cartons and labels for Sweden warehouses as part of the shipment rather than as a separate service.
How are RMA and DOA replacements handled on the WF-K self-service query terminal family?
Answer: AndroidSBC logs every board to its burn-in result, which is what makes RMA workable for Gothenburg integrators running Sweden estates across many sites.
