MCP23017 IO Expansion Board I2C Interface

This MCP23017 board adopts the I2C interface to achieve 16 I/O port expansion. It supports Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+/4B, as well as Arduino and STM32. We provide C and Python demo codes for Raspberry Pi, as well as demo codes for Arduino and STM32, which can implement input testing, output testing, and interrupt testing.

Note: There is no difference between SG-IO-E017 and SG-IO-E017-A in terms of circuit function, the only difference is their sizes.
