I currently have my sensehat connected to my pi3 using an extended header but since I have some spare dupont cable lying around, I want to use them instead. I understand the sensehat uses 6 data GPIOs, 1 3V and 1 5V pin. My question is how many ground pins does it need? 1 or 2?
I did look at http://pinout.xyz/pinout/sense_hat# but I am still confused. Yes, I could connect all the pins with the dupont cable but I only want to connect the pins in use and leave the rest for a PIR sensor.
Thanks for your help.
