With this breakout, you can integrate an MBUS master for up to 6 load units on your own PCBs or use it for test setups with any controllers. (In the picture above, the module is integrated on an MBusino circuit board ). Thanks to its compact design of just 33mm x 30mm, the master module fits on any PCB. The connection is made via pin headers on the back, which are arranged in a 2.54mm grid.
