Product Description

The MikroElektronika MIKROE-1889 4 x 4 Key Keypad MikroBus Click Board is a precision development kit designed for embedded system designers and developers requiring a compact, reliable human-machine interface. This board integrates a 16-button keypad arranged in a 4x4 matrix that enables simultaneous multi-key input for complex interaction scenarios.

The keypad's button states are captured through a pair of 8-bit parallel-in serial-out shift registers, enabling efficient and rapid data transfer to the host microcontroller. The board interfaces with target microcontrollers via the SPI mikroBUS™ protocol, making it compatible with MikroElektronika's mikroBUS™ standard development boards. Operating voltage flexibility (3.3V or 5V) enhances its integration capability across various systems.

The PCB features silk screened legends, improving usability by clearly identifying each function key. This Click board is suitable for industrial, laboratory, embedded, and educational applications where custom keypad input is essential. Header strips come pre-soldered, allowing quick deployment for prototyping or production.

Designed to fulfill RoHS compliance, the MIKROE-1889 adheres to environmental standards ensuring safe and responsible usage. Typical applications include control panels, security systems, industrial equipment interfaces, and development kits for automation.

The 4x4 keypad matrix provides 16 tactile button inputs. Shift register-based communication ensures efficient keypad status reading. SPI mikroBUS™ interface for effortless MCU connectivity. Operates at 3.3V or 5V power supply levels.

Silk screened legends on PCB aid clear identification of pushbuttons. Pre-soldered header strips simplify mounting and integration. Compliant with RoHS standards for environmental safety. Suitable for embedded, industrial, educational, and prototyping environments.
