I ordered myself one of these LoRaGo PORTs. I can confirm that the default reset pin (22) is the correct one for this board. I however do get that it takes a few tries before the concentrator successfully starts. I also had to bring the SPI speed down a bit using:
SPI_SPEED = 1000000
Regarding the LoRaGo PORT kit, I am impressed by how easy it is to plug everything together and on top of a raspberry pi. I was even able to reuse an existing Pi that had a Linklabs shield plugged on top of it.
One issue that I encountered was that the u.FL to SMA cable that I received was not the correct type. I got a u.FL to SMA-R (reverse polarity) cable, and the antenna is SMA. So the antenna can not be connected to the board. The antenna itself is also not that great at 868MHz. So if you are planning to get one of these boards, order your own u.FL cable and a proper antenna.
