Details: Overview

The MCP23017 I2C Port Expander Module designed for GPIO expansion, embedded development and electronics prototyping. It uses the I2C communication interface to provide 16 additional digital I/O channels, helping
reduce pin usage on the main controller while expanding project connection capability.

Based on the MCP23017 GPIO expansion chip, this 16 channel GPIO Expansion Board can be used for digital input, digital output and interrupt function testing. It is suitable for projects that require extra control pins, such
as LED control, switch input, sensor signal expansion, relay control signal output, teaching experiments and custom microcontroller interfaces.

The SG IO E017 supports both 3.3V and 5V working levels. It can be used with compatible with Raspberry Pi Zero, Zero W, Zero WH, 2B, 3B, 3B+, 4B, compatible with Arduino boards, STM32 controllers and other I2C host
platforms.

For flexible wiring, the board provides a PH2.0 interface and reserved 2.54mm pitch pads. This allows users to connect the module to jumper wires, breadboards, custom circuits and other development boards according to
different project structures.

The onboard 3-digit DIP switch allows convenient I2C address adjustment, making it easier to use multiple I2C devices in one system. Demo codes are available for C and Python on Rasp-berry Pi, as well as examples for Arduino
and STM32, helping users start testing faster.

Please note: SG-IO-E017 and SG-IO-E017-A have the same circuit function. The main difference is the board size.
