Hi indoor farmers out there.
My friend and I first planned to build the PFC V. 2.1 and then changed our plan because of our missing Know-How in programming etc. So we ended up building the MVP version.
Now we ordered two Signal Boards from @iancollmceachern, which are already fully assembled and even with the Arduino Headers, and the Ribbon Cable Header.
If there is anyone out there looking for a Signal Board send us a message.
