About this item

  • 【5-SET SOFT KEYPAD KIT (5 KEYPADS + 5 I2C ADAPTERS)】Includes 5 flexible soft 4x4 matrix keypads (16 keys each), 5 I2C adapters to simplify connections, and a storage container — suitable for multiple projects or backups.
  • 【SOFT MEMBRANE KEYPADS WITH EASY MOUNTING】Each keypad has a flexible design with double-sided adhesive tape on the back for attachment to project boxes, desks, or enclosures — for custom interfaces in robotics, security systems, or prototypes.
  • 【GPIO-SAVING I2C ADAPTERS】The included adapters enable I2C communication using just 2 GPIO pins (SDA and SCL) instead of the traditional 8, freeing up pins on your microcontroller. Compatible with Arduino, Raspberry Pi, ESP32, and more.
  • 【WIDE COMPATIBILITY】Keypads and adapters support 3.3V to 5V operation for a wide range of MCUs. Easy to program with libraries like Keypad_I2C for quick setup.
  • 【VERSATILE APPLICATIONS】Use these 4x4 keypads for numeric entry, menu navigation, or custom controls in IoT devices, home automation, smart locks, and educational projects. Soft, responsive keys provide tactile feedback in a compact form.
