4x3 Keypad for microcontrollers

thingiverse

These are the files for 4x3 Keypad, No need for flexible material, I printed with PLA. The keys must be printed separately. The Keypad electronic files schematic and PCB are attached herewith, you'll require Proteus 7.6 to open them. In PCB you need to increase the board size and point the drill holes, it can be done manually, no editing in PCB design in required. You can contact me if you require the solidwork files for the printables. Overview and Background 4X3 Keypad This is a sort of case and keys for a keypad used generally with microcontrollers. Usually the ready-made keypads are weak, and does not usually carry aesthetic value. I usually do not prefer buying ready-made products and like to build my own as per my need. This is hence an effort to develop a relatively more robust and good looking keypad for the projects we build. Good luck to the users! Lesson Plan and Activity
