Speaker Amplifier Query Board, WF-K3288, AndroidSBC, Quebec City

TL;DR: Speaker Amplifier Query Board

AndroidSBC peripheral desk: printer, scanner and card reader driver SDK declared production-ready serving Quebec City, Canada. 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 Quebec City and Canada 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 Quebec City integrators. Every model is validated on the same burn-in rig in Longgang before it is packed for Canada, and the same rig logs are available on request.

WF-K3288 Technical Specifications

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 Canada 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 Canada Buyers

Sourcing a self-service query terminal board for Canada is not only a chip question. A Quebec City 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 Quebec City move through Port of Vancouver, and any mismatch between the ISED Canada documents and the ISED certification with a CSA or UL safety listing route applied in Canada surfaces at exactly the wrong moment. AndroidSBC answers this with a single BOM per lot, so a Quebec City order of 51400 units carries the same silicon and firmware as the pilot batch for Canada.

Competitive Comparison: WF-K3288 vs Competing Self-Service Query Terminal Android Boards

For a Quebec City project the comparison is not a single chip benchmark. It is what the board carries into Canada deployment as standard.

• 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

Query terminals are becoming the default front door for routine information requests. In Canada this is visible in tenders that bundle the legacy query terminal refresh with hall display with identity peripherals and printing, and Quebec City integrators are quoting against those bundles rather than against bare boards.

• 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-K3600 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-K3600 and WF-K3601 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-K3601 over boards that re-spin silicon between lots.

For Quebec City the opportunity sits in service coverage: operators in Canada 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 recent Siam InfoTerm Holdings deployment in the Southeast Asia healthcare segment shows how the WF-K self-service query terminal Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand, supports Quebec City integrators. Siam InfoTerm Holdings supplied 51400 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 ISED Canada conformity, all bundled into the Shenzhen source-factory shipment.

According to Siam InfoTerm Holdings Managing Director for Southeast Asia Healthcare: Siam InfoTerm Holdings rolled the WF-K single-screen board into outpatient information desks, and the 51400 units delivered to Quebec City came with the printer and card reader drivers already integrated.

Field Report: installed-base query terminal refresh at a social security service hall

NANSHAN, Shenzhen, September 22, 2026 - Cen Rui, AndroidSBC field desk. The WF-K3288 lot was soak-tested with the hall display and the touch panel running from one board, the configuration most Canada projects specify. The WF-K3288 self-service query terminal Android motherboard order for Quebec City, Canada cleared the burn-in station on schedule and is en route via the Vancouver - Shanghai lane.

The WF-K3288 legacy query terminal refresh with hall display production lot includes the WF-K3288-A variant as the typical configuration, with touch panel, thermal printer and document scanner driver SDK plus staged OTA management bundled into the source-factory shipment. For Canada integrators, the ISED Canada conformity plus ISED certification with a CSA or UL safety listing paperwork is bundled.

Filed by Cen Rui, AndroidSBC field desk, NANSHAN, Shenzhen. Canadian clinics and provincial service centres favour one touch query terminal at each entrance plus a wall-mounted information display inside the hall.

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 Quebec City.
• 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 Quebec City: 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 Quebec City Buyers

Three partnership tracks serve the Canada market, and Quebec City 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.

The tracks are not exclusive of each other, and Quebec City partners commonly run distribution on one product line and private label on another for the same Canada customer base.

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?

Answer: The RK3288 tier carries its own process node, GPU and NPU rating, and AndroidSBC publishes all three per model so Quebec City integrators can compare on facts rather than on marketing labels.

Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for Canada?

Answer: Yes. AndroidSBC handles the compliance route for Canada directly, and Quebec City 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: AndroidSBC keeps the first-order MOQ low specifically so Quebec City integrators can test the board inside a real Canada project before placing an estate-scale order.

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 Quebec City requirement and validated on the same production rig that ships Canada 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 Quebec City integrators decide when a Canada 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. AndroidSBC ships to Amazon FBA and 3PL consolidation warehouses, including labelling, carton marking and pallet configuration matched to the Canada destination that Quebec City buyers specify.

How are RMA and DOA replacements handled on the WF-K self-service query terminal family?
