Description
The device IO Expander MCP23017 Breakout by Soldered uses the MCP23017 IC to expand the number of digital input/output lines available to a microcontroller through the I2C bus. The IC provides 16 GPIO lines divided into two 8-bit ports, A and B. Individual lines can operate as inputs, outputs, or inputs with internal pull-up resistors.
Communication with the microcontroller requires only the SDA and SCL lines. The board also provides INT A and INT B outputs for interrupt-based input handling without continuous polling. The RST pin provides hardware reset control.
Two Qwiic connectors simplify integration with compatible boards without soldering signal wires. The module can be used to handle additional pushbuttons, LEDs, control signals, and other digital peripherals in projects where the microcontroller does not provide enough GPIO pins.
The product page specifies an MCP23017 operating voltage range of 1.8–5.5V, while the board hardware documentation specifies support for 3.3V or 5V through the VCC pin. Board dimensions are 38 × 22mm. The 3.2mm mounting holes are designed for M3 screws.
