Advanced 16-Channel I2C Relay Module

Experience seamless control and automation with our state-of-the-art relay module, designed to enhance your projects with efficiency and reliability.

Key Features:

• Built Around the PCF8575 Chip: Utilizes a 16-bit I2C I/O expander to manage 16 relay channels, minimizing GPIO pin usage for your Raspberry Pi, ESP32, ESP8266, or other controllers.
• 16-Channel I2C Relay Control: Effortlessly control up to 16 electromagnetic relays from a single module. Connect up to 8 boards on each I2C bus, allowing for control of up to 128 relays using just 4 wires!
• SPDT Relays with LED Indicators: Each channel features SPDT contacts (Normally Open, Common, and Normally Closed) along with individual LED status indicators for quick visual confirmation of relay status.
• Compatible with 3.3V and 5V Logic: Designed for versatility, this module operates seamlessly with both 3.3V and 5.0V systems, making it ideal for a variety of microcontrollers and SBC-based automation setups.
• Long Relay Service Life: Built to last, this module is rated for a minimum of 10,000,000 mechanical operations and 100,000 electrical operations at rated load.

This relay module is perfect for DIY enthusiasts and professionals alike, providing robust solutions for home automation, robotics, and more. Enhance your projects today!
