Review machine design
Share machine photos, existing board, connector needs, interface notes, and target workflow.
OEM machine control board
OEM control board for unattended and self-service machines.
Use QuLink when a standard board is close, but your machine needs custom connector layout, firmware behavior, enclosure, payment workflow, data upload, or repeat deployment support.

Project fit
When OEM makes sense
Buyer signals
- You are a machine manufacturer, system integrator, or operator planning repeat deployment.
- The machine has special wiring, connector, enclosure, protocol, or firmware behavior.
- You need one board family to support API control, telemetry, and optional QR payment.
- The project should move from sample test to batch deployment with stable documentation.
What to send first
- Machine photo or existing board photo
- Interface or wiring note if available
- Target action after API command or payment
- Whether telemetry or data upload is required
Not the right fit if
- You only need a pure payment acquiring account and no machine-side control.
- There is no physical machine action after payment, booking, or API approval.
- The project has no machine photo, board photo, wiring note, or interface clue yet.
Integration model
Customize the machine-side layer, not your whole platform
Your cloud, app, payment provider, pricing, and customer data can stay yours. QuLink customizes the board, firmware, connector, and machine integration layer.
- Customization
- firmware, connector, enclosure, wiring harness, output logic, telemetry format
- Interfaces
- MDB, pulse, relay, UART, RS485, serial, sensor input, QR payment trigger
- Server integration
- API commands, signed references, webhook events, data upload
- Project mode
- sample validation, pilot batch, production revision, repeat deployment
Workflow
From machine interface to API-controlled result.
Prototype board behavior
Confirm command, data, payment, and physical action behavior on a sample unit.
Stabilize integration
Lock wiring, firmware rules, event format, and enclosure or connector decisions.
Prepare repeat rollout
Move to pilot batch, production revision, and long-term support plan.
API example
A clear server command or webhook for the machine-side action.
The exact command fields depend on machine interface, firmware profile, and whether payment or your own app triggers the action.
POST /v1/devices/{device_id}/commands
{
"command": "start_session",
"source": "operator_app",
"machine_action": {
"interface": "custom_oem",
"profile": "CABINET_V2"
}
}
Project RFQ
Send a machine photo. We help identify the board, interface, and next test step.
Send machine photos, target market, expected quantity, interface requirements, and what the machine should do after a command or payment.
A good first message
If you are unsure about the exact interface, send what you have. Photos often answer more than a long spec.
- Machine type and target country
- Machine photo, board photo, or wiring photo
- Action after payment or API command
- Need data upload? expected quantity?
Fastest first step
- Send a machine photo
- Describe the action after API or payment
- Tell us if data upload is needed
FAQ
Questions buyers usually ask before a sample test.
Do we need large volume before discussing OEM?
No. A useful OEM discussion can start with samples, expected quantity, and the machine-side problem you need to solve.
Can QuLink customize both control and data upload?
Yes. OEM projects often combine physical control, telemetry, webhooks, and optional QR payment.
Can we keep our own app and backend?
Yes. QuLink focuses on the machine-side board and integration layer; your platform can keep business logic and data ownership.
