This is a 10-pin socket with 2mm pitch that mates with the popular XBee radio from Digi. Use this small part to avoid having to solder your precious radio to a PCB. You’ll need two of these sockets to connect to all 20 pins on the XBee.
These headers can also be cut to work with the RFID breakout board.
Please Note: This item is sold singly, not in pairs.
