Pluggable Connectors for Raspberry Pi IO Cards
We provide all the required plugs with each card, but sometimes customers want to have spares, or loose some parts.
The male connectors are soldered on the board. The female part holds the wires, usually 13 - 22AWG, with screws. Pitch is from 3.5mm to 5.08mm.
A good source for buying spare connector plugs is Newark. Same parts can be found at Digikey and Mouser.
