The pi-topPROTO+ board pin layout can be found here.
Thank you for this! In the pi-top tutorial: Getting Started with Physical Computing, they are instructing to use the GPIO pins on the Raspberry Pi to connect an LED. However the cooling bridge is already installed on the Raspberry Pi GPIO pins. Am I supposed to install another Raspberry Pi to do the tutorial?
Additionally, is the Pi-top PROTO+ 3.3V only or is there a 5V power supply as well? Only one side is labelled 3.3V.
bolth sides are 3.3v "VCC" is a key
