Punch in your secret key into this numeric membrane keypad. This keypad has 4 buttons, and since every key has its own wire line, no matrix code is required - just treat these like every day switches. The membrane is soft and has a removable paper backing to expose a strong adhesive so you can stick this on an enclosure and feed the cable through a slot. Its a simple keypad but that's why we like it. We include a 5-pin extra-long header strip so you can plug this into a breadboard with ease. Check out this detailed guide with wiring diagrams, libraries and example sketches for all sorts of matrix keypads. Technical Details Weight: 2.83g Keypad dimensions: 69.14mm / 2.72" x 20.07mm / 0.79" Length of cable + connector: 87.31mm / 3.43" x 14.28mm / 0.56" 5-pin 0.1" pitch connector
