M-BUS HAT for Raspberry Pi

With this Raspberry Pi HAT you can extend your Raspberry Pi with functions for smart metering. The HAT provides an M-Bus master to which other M-Bus devices such as electricity, water or gas meters (with the appropriate interface) can be connected directly.

Features:

* M-Bus (Meter-Bus) Master
* powered by an external 9..30V DC voltage (36V for the MBUS will be generated internally from this voltage)
* up to 6 unit loads can be powered
* isolated interface
* selectable UART via jumper (with Raspberry Pi 4 only)
* indicator LEDs for RX and TX * removable block terminal for bus connection
