Thank you for your understanding. PCB connectors or pin headers for connecting blocked or isolated areas between circuit boards. Widely used in electrical circuits such as stepper motors, servo motors, radio-controlled airplanes, maintenance of computers and small electronic products, and interconnecting circuits. The size of the copper straight pin headers provided here is as follows: Pin row: 2; Pin pitch: 2.54 mm; Pin length: approx. 3 mm; Number of pins: 4P, 6P, 8P, 10P, 16P; In the package: Total 100 packs per set - 25 packs x 4P; 25 packs x 6P; 20 packs x 8P; 20 packs x 10P; 10 packs x 16P It is made of copper contacts with good conductivity. It can meet the needs of various transmissions of high voltage and large current. PCB pin strips not only make connections easier, but also make prototyping easier. 1. Board-to-board connection - Use independently or connect to a female header; 2. Board-to-wire connection - Connect to a wire. Pin headers get hot during operation, and high temperatures affect the decay rate and stability of LEDs.
