M-Bus Master Hat DS – The Original and Best
£35.00
M-Bus Master Hat DS. The original and best M-Bus Hat for your Pi. Turns your Raspberry Pi into an M-Bus Master, allowing you to read data from M-Bus wired meters, and also provides a DS18B20 temperature sensor on-board the Hat as well as the ability to wire in external DS18B20 sensors.
Supports Raspberry Pi 5 and all previous versions with 40-pin headers.
Comes in both full sized and micro versions, for standard Raspberry Pis and Pi Zeros, along with standoffs for mounting on your Pi.
Price includes UK shipping. Free untracked European shipping for orders above £42.50, free tracked shipping to Europe above £60. Worldwide shipping also available.
Key benefits of the M-Bus Master Hat DS:
- Comes with on-board DS18B20 temperature sensor, and terminal block to add external DS18B20 sensors
- No external power supply required – generates required voltage on-board
- Up to 3 Unit Loads (M-Bus slaves) supported*
- Supported by various open source packages, including libmbus, pyMeterBus, pyMbusHat and mbus-httpd
- We supply stand-offs with all Hats to securely and safely mount your hat to your Pi
