This is hopefully the final post concerning MBus-masters ... 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":
