“Nice kit. Does what it says on the tin. Or should I say did what it said on the tin.
I had a working system, changed the SD (same os, same code) and the relays have stopped working. I failed to note something that I did to allow the OS to get to the hardware. I can put on 1 of the LEDS using the standard code, but I can no longer make the relays switch. Seems to be a dirth of simple to use instructions on connecting the board to a PI4. I have enabled IC2 in preferences and that did not work. No, I dont have the old SD. Worse even if I did I now know I cant reproduce another ;-( Write it all down twice.”
“Really nice !
I just bought one with a special hat case an it fits perfectly !
I'm using it with a smal python flask app to do some domotic stuffs and it works really fine (state indicator leds are really usefull).”
“great addition to the pi allows a neat and easily atteched volt free output capability. as is the board sits a little proud of the official case so bear that in mind otherwise great little board.”
“I ordered this board for use with a Pi 1, which can be done with some short fly leads connecting up the power/ground and gpio pins.
It worked brilliantly to control a traffic light I’ve set up in my workshop.
Very pleased.”
“Easy to get set up, but would be nicer to make an easier job of selecting GPIO pins that you want to use. As it comes there's 3 jumpers that bridge 3 pins. If you want to use any other pins you need to remove the jumpers and make your own connection. This works fine, but can leave the board looking a bit messy. Would be nice to have some onboard solder-bridges or something to allow simpler pin selection.”
