4x4 matrix keypad module measuring 65 × 68 mm, designed for use in microcontroller and embedded system projects. The keypad uses conductive rubber keys over a PCB contact layer, providing reliable input for digital circuits.
- Key arrangement: 4 rows × 4 columns (16 keys total)
- Dimensions: 65 mm × 68 mm
- Contact type: conductive rubber over PCB
- Maximum current per contact: approx. 10 mA
- Contact resistance (pressed): < 1 kΩ
- Recommended operating voltage: ≤ 35 V DC
- Connector: standard 8-pin row/column interface
The keypad can be easily interfaced with microcontrollers such as Arduino, ESP32, STM32, or Raspberry Pi. Multiple Arduino libraries are available for matrix keypads, supporting straightforward integration into projects.
Suitable for applications such as password entry, menu navigation, and control panels in hobbyist and educational electronics.

There is no schematic included but it only takes a minute with a multi-meter to figure it out.

This keypad is well built and worth the few dollars it cost. I find the keys more precise and actually easier to activate than the membrane style. The order was on time and well packed. Thank you
