Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →An Arduino stackable header connector with four pins and an 11mm height. Eleven mm is a great stitch length for stacking Arduino shields.
A stacking header is a specific type of female breadboard pitch connection that has long male pins on the bottom. These expanded male pins enable circuit boards to be linked without a tangle of wires and remain detachable, and they are compatible with the female sockets on many well-known microcontrollers. This specific header has a single row of four pins. The female sockets are 8.5 mm height, while the male pins are 11 mm long.
Ans. With a pitch of 2.54mm, it fits in standard breadboards, requiring only some height adjustment.
Ans. These are made from brass with a tin and gold-plated finish for corrosion resistance
Ans. Certainly, these headers can be soldered easily onto PCBs or prefboards.
Ans. For sensor modules pin can directly plug into these headers.
