I replaced the Arduino Micro Pro in the "A better MBus-Master" design by a Teensy 3.1 and attached a WIZnet Ethernet module. Also, I put in a dedicated power supply providing 3.3V, 32V and 34V, based on two MC34063. 3.3V for the Teensy and the WIZnet. 34V to power the devices of the analog part of the design. 32V for the bus. This give all the devices in the analog port 2V headroom. The "receive path disable MOSFET" has been removed again. Bringing the Teensy to reliable work was a bit hard, but this follows in another post. And this it is and it works: And finally it is in "production": ')
