Description
A 24-channel input/output port expander module controlled via I2C interface. It is based on the CH423 chip. Each IO pin can be configured as an input or output, including 8 with a hardware interrupt function. The maximum output current should not exceed 15 mA, and the pins are compatible with 3.3 V and 5 V. The expander will prove useful for LED lighting or matrix display projects. Full documentation is available on the product wiki page.
