極性的連接器 - 接線引腳

資料來源：https://www.sparkfun.com/products/8100

Polarized connectors and headers for your perf board/PCB projects. Use these connectors for power connections or any sensor/general connection to prevent users from connecting the peripheral incorrectly or reversed.

This is for a pack of 20 individual crimp pins. We regularly use a pair of needle nose pliers and a soldering iron to attach these pins. No special tools required. Be sure to order the mating header and housing!
