With this M-Bus HAT for Raspberry Pi, 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. A datasheet/user guide is available to help you get started. With libmbus, powerful C++ software is available for the Raspberry Pi, which can be used with the M-Bus HAT. If you prefer Python take a look at the pyMeterBus project. Features * M-Bus (Meter-Bus) Master * Compatible with European standard EN 13757-2 * For the remote reading of consumption meters * For up to 6 unit-loads (9mA) * Power supply by Raspberry Pi or external DC power supply (9-30V) * Galvanically isolated interface * Removable screw terminals for bus and power supply connection * Indicator LEDs for RX and TX signals * Selectable UART via jumper (with Raspberry Pi 4/5 only) * For Raspberry Pi 2 / 3 / 4 / 5, Raspberry Pi Zero and compatible SBC Resources * With libmbus, powerful C++ software is available for the Raspberry Pi, which can be used with the M-Bus HAT. * If you prefer Python take a look at the pyMeterBus project. * V2.0 Datasheet * M-Bus homepage Package Contents * 1x M-Bus HAT (standard version) * 1x Terminal block connector * Shorting headers Raspberry Pi not included Revision History * As of 23/04/2025 we are stocking v2.0 https://elecena.pl/product/22727632/m-bus-hat-for-raspberry-pi-v2-0 2023-03-07 https://elecena.pl/product/22727632/m-bus-hat-for-raspberry-pi-v2-0 2023-12-27 https://elecena.pl/product/22727632/m-bus-hat-for-raspberry-pi-v2-0 2024-09-18 https://elecena.pl/product/22727632/m-bus-hat-for-raspberry-pi-v2-0 2024-11-29 https://elecena.pl/product/22727632/m-bus-hat-for-raspberry-pi-v2-0 2024-11-30 https://elecena.pl/product/22727632/m-bus-hat-for-raspberry-pi-v2-0 2025-04-23 https://elecena.pl/product/22727632/m-bus-hat-for-raspberry-pi-v2-0 2025-11-28 https://elecena.pl/product/22727632/m-bus-hat-for-raspberry-pi-v2-0 2025-11-29
