- 【16-Bit I/O Expansion with I²C Interface】 16-bit quasi-bidirectional I/O ports expand microcontroller capabilities; supports I²C/SMBus communication at 400kHz; Suitable for for Arduino, for Raspberry Pi, and STM32 projects.
- 【Flexible Address Configuration for Multiple Devices】 Three hardware address pins (A0/A1/A2) allow up to eight modules in parallel (addresses 0x20–0x27); easy setup for multi-device systems without conflicts.
- 【Low-Power Design for Battery-Powered Applications】 Standby current ≤10µA; working current ≤100mA; suitable for portable and energy-efficient systems; compatible with 2.5V–5.5V power supplies.
- 【Integrated Level Shifting for Universal Compatibility】 Built-in 3.3V/5V level conversion circuit; works seamlessly with popular controllers like ESP32 and for Raspberry Pi; no external components needed for basic use.
- 【Reliable Interrupt Output for Real-Time Monitoring】 Open-drain interrupt output (INT pin) triggers on input state changes; requires 10kΩ pull-up resistor; enhances system responsiveness in automation and control applications.
