16-Bit I/O Expansion: Adds 16 programmable GPIO ports via I2C bus (400kHz), ideal for sensors, LEDs, buttons, and fan control. Universal Compatibility: Works with Raspberry Pi (BCM2835), Arduino UNO R3 (ATmega328P), and STM32F103 boards. Pinout guides included. Advanced Interrupt Handling: Active-low interrupt output triggers real-time input change alerts, reducing CPU polling. Plug & Play: 3.3V/5V dual voltage support. Built-in polarity inversion registers and power-on reset. Multi-Platform Support: Includes C/Python code for Raspberry Pi, Arduino IDE examples, and Keil uVision5 project for STM32.
