IO Expand Click
Overview
The MIKROE-2880 IO Expand Click is an I/O expansion board designed for the mikroBUS socket architecture, providing additional GPIO capabilities to a host microcontroller. It operates on a voltage range of 3.3V to 5V and utilizes the MCP23S17 16-bit I/O expander with an SPI interface to minimize pin count on the master MCU.
Why Choose This Part
The board uses the industry-standard SPI interface for high-speed communication and includes configurable interrupt pins for efficient event-driven programming. Its compact L-sized form factor (57.15 x 25.4 mm) integrates seamlessly into any mikroBUS-compatible development system.
Applications
Key Specifications
Getting Started
Plug the Click board into a mikroBUS socket on a development board such as the Mikroe Fusion or EasyPIC. Use the MCP23S17 SPI library provided in the MikroSDK or standard C libraries to configure the registers for input or output modes.
