M-BUS Slave FeatherWing

This M-BUS Slave is an add-on board for Feather microcontroller boards, which act as M-Bus (meter bus) slave nodes. It uses the TSS721 M-Bus Transceiver IC and has an isolated interface.

This FeatherWing can read consumption meters with a P1 customer interface, such as electricity meters, or be used to create custom M-Bus meters. Software support includes example codes for the Arduino IDE to read meters and implement simple meter functionalities.
