#Pi Stop Traffic Lights
The PiStop is placed vertically into the GPIO connectors and can be fitted into several positions in the board. It can be fitted into 26-pin headers as well as 40-pin headers. It only uses 3 GPIO pins plus ground, but you can fit multiple PiStops into one header, although not all positions are possible simultaneously as some pins are shared across the options.
