M-Bus MKR Shield

This Arduino MKR Shield will extend your Arduino MKR with smartmetering functions. The shield will provide a small M-Bus Master interface to connect and power meters or other M-Bus devices directely to the M-Bus terminals of this shield.

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
• can be combined with any Arduino MKR board or Portenta H7

Software:

We are providing code of  a simple data repeater to analyse M-BUS data via an connected PC and also a basic M-BUS master to readout M-BUS slaves directly with the Arduino MKR.
