Car Wash Bay Kit
Self-service car wash bay electronics
- 3 boards · one bay
- 16 MOSFET outputs
- QR · card · cash
Three boards that together cover everything a self-service wash bay needs: payment with fiscal receipts, control of the valves and the high-pressure pump, and a display for the customer. M-VEND runs the bay, M-RELAYS drives the bay relays on 16 MOSFET channels, ESP-Matrix drives the LED display, and the bay is managed from one cloud operator account.

Questions we get first
What is in the kit for €500?
Three boards: the M-VEND controller, the M-RELAYS 16-channel MOSFET relay driver and the ESP-Matrix LED display controller, with car wash firmware, addresses and wiring between them already set and the bay connected to the cloud operator account. Programmes and tariffs are configured for your bay before shipping. The price is per bay, VAT excluded.
What is not included?
LED panels for the display (sized to your bay), payment devices such as a contactless terminal, bill acceptor or coin acceptor, the power supply and the enclosure. We can select them together with the kit.
How many bays does one kit serve?
One kit per bay. A multi-bay wash takes one kit per bay, and all bays are managed in one cloud account with shared statistics.
Why a separate output board if M-VEND has its own outputs?
M-VEND outputs carry control signals. M-RELAYS adds 16 MOSFET channels, addressed over Modbus RTU, that switch the coils of the relays and contactors which in turn power the valves, the high-pressure pump, chemical dosing, lighting and heating — with spare channels for extra programmes.
What does the display show?
During a wash: the selected programme, the time left and the tariff. When the bay is idle: customer hints, adverts or announcements sent to the display remotely. Any LED panels with a standard HUB75 connector work.
Is there a warranty and do you ship abroad?
The hardware has a 12-month warranty. International shipping is by DHL or FedEx; we issue an invoice after the order details are agreed.
