First prototype

MDB+RS232toUART controller

About the project

About the project

The controller emulates an MDB Cashless device; it's managed via UART by virtually any device. It has a 5V power supply and an RS232 interface for connecting a POS terminal, which is also controlled via UART. MDB and UART interfaces are galvanically isolated.
