M-Bus Slave HAT for Raspberry Pi Pico

This M-Bus Slave HAT is an add-on board that allows the Raspberry Pi Pico to function as an M-Bus (meter bus) slave node. It is based on the TSS721 M-Bus Transceiver IC and provides communication via UART0 or UART1. The HAT features an isolated interface and can be used to read consumption meters with a P1 customer interface or create custom meters for M-Bus systems. Software support includes example codes for Arduino IDE to read meters and implement simple meter functions. We also have the M-Bus Master HAT here Note: Raspberry Pi Pico is NOT included Features
