This Arduino MKR shield expand your Arduino MKR with functions for smart metering via meter bus (M-BUS). With the M-BUS Master Shield you can read consumption meters for heat, gas, oil, water that have a built-in M-BUS slave interface.
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
- Can be combined with any Arduino MKR board or Portenta H7
