Controllers and modules

A field-proven controller for water vending machines. Handles QR and contactless payment, bill and coin acceptors, and reports every sale to a back office. Temperature, analogue, flow and TDS inputs let one board run both the dispensing logic and the water-quality monitoring.

Automation controller for water vending points serving one or two water types — plain fill and reverse osmosis. Auto-calibration and filter monitoring reduce the service visits a route operator has to make.

The electronics of one water vending machine in a single order: the M-AQUA controller runs dispensing, sensors and payment, a 3.5″ touch display shows the customer the tariff and the QR code to pay, and four Weidmüller relay modules switch the pump and the valves. The display firmware is already paired with the controller and the machine is set up in the cloud operator account before shipping.

A general-purpose vending controller for snack, coffee and combo machines. Accepts cash and cashless payment on the same board, exposes telemetry for remote monitoring, and drives a panel or LCD that shows the payment QR code.

Built for machines that mix rather than just dispense: syrup dosing, carbonation and several flavours on one board, with the same payment and back-office stack as the rest of the range.

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.

A stripped-down version of the QRport fiscalization module for vending and self-service machines. Same cloud fiscal receipt flow, fewer functions, lower unit cost — meant for fleets where fiscalization is the only requirement.

A small bridge board that sits between a machine controller and its serial periphery — fiscal device, printer or payment terminal. Two independent UART channels, an inhibit line and two IDC-10 harness connectors let it drop into an existing loom instead of forcing a rewire, and the onboard step-down converter runs it from the machine's own supply.

Sits on the MDB bus of an existing machine and fiscalizes every device on it — bill validators, coin changers and contactless readers — for both cash and cashless payments. The same board works as an MDB ↔ RS-232 converter, so a machine with an MDB bus can talk to equipment that only speaks serial.

A Wi-Fi lighting controller that drives four PWM power channels — RGBW or four independent single-colour strips — and addressable WS281x pixels from the same board. The MOSFET stage sits on heatsinks and lands on screw terminals, so the board goes straight into a luminaire or a control box without an extra driver stage.

An ESP32 board with a pair of expander drivers behind an IDC-10 header: it runs an LED matrix or a keypad-style I/O matrix over Wi-Fi while the screw terminal block carries power and the discrete lines. Two user buttons and a reset button are on the board, so a unit can be configured without opening the enclosure wiring.

The entry board of the range: four opto-isolated inputs, two relay outputs and a 12 V supply, with a UART-TTL header and an LCD connector for a local panel. A socket for a radio module turns the same board into a networked unit, so one design covers both the standalone gate and the connected one.
