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.

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.

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.
