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.
Thanks again, Rongzhong!
After more debugging, I finally managed to have both my Pi 3's and Pi 4's serial port working.
For Pi 3, I just made sure my raspi-config was reset correctly and so on and it can be mounted without problem.
For Pi 4, I followed the solution mentioned in:
However, I find that I still can't mount the Pi 4 directly onto the 2x5 socket as the serial port will not have respond then. When I first power up the Pi 4 separately with another power source and then mount it up and then remove the power source, it would work then. It seems to me some power-up sequence from the Nyboard may not work well with the power-up sequence from the Pi 4 ubuntu somehow?!
Please let me know if you would have any other suggestion too.
Thanks again!!
