Attention: MicroBCU has no dedicated pins for WAGO terminal (Red/Grey)!
Developer Documentation
Build It
If you solder the MicroBCU yourself, be carefull: On (some?) PCV Rev 1.2 the solder print on the top (NCN-) side is wrong. The two capacitors C5 and C6 in the top right corner are switched - here you can see the correct soldering:
https://github.com/KONNEKTING/KonnektingHardware/blob/master/MicroBCU/R1.2/Board_top.pdf
Also be carefull wenn soldering the big capacitor C2: The solder print marks the + side of the capacitor, because this is the standard for tantalum capacitors. If you use aluminium capacitors, the - side is marked.
