I installed this and was able to control the relays through the terminal, with the program working as it should. The terminal would tell me that I had 1 relay board attached, which was correct. However, after some time had passed I tried it again and now it did not detect any relay board. To test this I swapped out for another microSD card and tried again. This time, it told me that there were 8 relay boards attached, when there was only 1 (I tried using these anyway and there was no way to turn on the relay from here). I tried swapping out the pi itself and the relay board attachment, but nothing changed. It seems to be entirely dependent on the sd card, even after reboots, whether it displays 0 or 8 boards. I have no idea what to do, thanks.
