Introduction

This IO expansion board based on the CH423 chip extends 24 digital ports via I2C, including 8 GPIOs with interrupt functions and 16 GPOs.

CH423 has a built-in current drive circuit that offers a 15mA continuous drive current, which can statically drive 24 LED tubes or dynamically drive 128 LEDs. This CH423 I2C to GPIO IO expander is suitable for projects involving LED tubes, dot matrix screens, light cubes, etc.
