Pinpad keypad 4x4 matrix keyboard for Arduino, ESP8266 or ESP32
thingiverse
Pinpad base plate and cover plate designed specifically for simple 4x4 matrix pinpad keypad keyboards that can be easily connected to microcontrollers like Arduino, ESP8622, or ESP32. No screws are needed; the cover plate simply fits snugly over the base plate. Optional glue can be used to secure them in place, but I have chosen not to do so. Infill and resolution settings should have little impact on the final product, leaving it up to personal preference and printer specifications. For my print, I selected 30% infill with a resolution of 0.15mm and brim adhesion. The necessary electronics hardware can be obtained for approximately $3 from various online retailers, including https://www.aliexpress.com/item/4000641987380.html or https://www.aliexpress.com/wholesale?SearchText=keypad+matrix+arduino.
