Mostly one layered project (except one wire) with Arduino pro mini 3v3 board and LoRa RA-2 module. Soldering the shorter header 1x6 strongly optional, in that case you have to solder the LoRa 3v3 pin to Arduino regulated 3v3 VCC.
UPDATE: PCB V1.1 has no 1x6 header (FTDI).
Be careful with the PCB, because the LoRa module was flipped and the nets were not renamed. It is ideal for home etching with (not?) mirrored print (as a final result, the conductive layer must be mirrored) and one layered PCB. Solder the LoRa module to the conductive layer. Then the Arduino should be placed on the side opposite to the LoRa module (on the silk screen/non conductive side). See the attachments!
Do not order this PCB from the manufacturer!
