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 →In this world nothing can be said to be certain, except we need headers, headers, and more headers!
Each pack contains five 36-pin short female headers, 0.1" pitch. These headers are very short for fitting into tight spaces with a height of just 5mm instead of the 'standard' 8mm.
Female headers are like the duct tape of electronics. They're great for connecting things together, soldering to perf-boards, sockets for wires or break-away header, etc. We go through these guys real fast, and thought that given how handy they are, we'd offer them in a pack of five!
These headers are even gold plated so they wont oxidize! You can cut these down to different sizes fairly easily. First, count how many positions you want as the final piece, then pull out the next pin using a pair of pliers. Finally, cut through the empty spot with diagonal cutters. You can clean off the half-spot using a file or with the diagonal cutters.
