Hello! I am a beginner of Bittle and I am trying to connect my Pi 4 to the Nyboard V1_0's 2x5 socket but I read that once I solder the socket, the original back cover can't be used. Therefore, I would like to ask if any way I can buy just one extra Nyboard V1_0 for experiments with Pi please. In fact, I got the Pi 4 USB connection to use with the ardSerial.py ok but not sure if the same would work for the 2x5 socket yet and so I have concern to solder the socket... Thanks in advance.
