This M-Bus Slave Shield is an extension board made for the Arduino MKR series, allowing it to function as an M-Bus (meter bus) slave node. It uses the TSS721 M-Bus Transceiver IC and communicates with the MKR board via UART.

It has an isolated interface and can be combined with any Arduino MKR board or the Portenta H7. It lets you read consumption meters with P1 customer interfaces or create custom M-Bus meters.
