Hey is there any way to hook on an wireless transmitter to the old OSPi which has the extra relay on it?
Hi,
I am not sure about an extra relay, but I managed to hook up a 433mhz transmitter and hc-sr04 to the unused GPIO pins on the Pi, without affecting the OSPi.
You can see the pins used and available in the end of the OSPi docs.
Cool that’s an option that I should try out.
Thanks.
