I've found a 5v relay board which is twice cheaper in comparaison with a board with 40 pin stacking header.
I can wire the Pi to the relay board using jumper cables but it look like messy.
My wish is to plug the Pi to the relay board but the problem is that the relay pin are
GND | IN1 | IN2 | IN3 | VCC while on the Pi the 5v pins are followed by a GND, 3 GPIO then an other GND.
So is it possible to change the first GND to act as a GPIO? Or maybe there is a connector which may suit the need ?
