Pin Headers

These modules and their shields come with no pins soldered to them, you can directly connect wires, or solder in one of the 3 sets of header pins they come with.

  • Sockets with short pins - Board to be bottom of stack
  • Sockets with long pins - Board to be middle of stack
  • Short Pins only - Board to be top of stack

As always with these boards, sockets should face up, pins down.

whilst some boards, like the button or screen, should only really be the top of the stack, some others will be happy in the middle or bottom of a stack, so choose which headers to solder on with that in mind.
