16 Channel I2C Relay Board With PCF8575 Expander For Arduino Raspberry Pi ESP32 3.3V And 5V Control Up To 10A Per Channel With Onboard LED Indicator SCL And SDA Pins
✔️ 16-channel I2C relay board with SPDT, LED, 3.3V/5V, single board
This 16-channel I2C relay board is built around the PCF8575 I/O expander to drive 16 SPDT relays from a single I2C bus. It’s a solid fit for Raspberry Pi, Arduino, ESP32, and other microcontrollers, making it handy for home automation, control panels, and automation projects.
✅ 16-channel I2C control via PCF8575 expander✅ SPDT relays with NO/NC/Common and LED indicators
✅ 3.3V and 5V logic compatible; I2C address 0x20-0x27 via DIP switch
✅ Max per-relay current 5A to 10A depending on voltage
✅ Board size 135 mm x 150 mm (5.31 x 5.91 in)
✅ Up to 8 boards per I2C bus, 128 relays total
✅ Fully assembled module, ready to drop into projects
💡 What is an I2C relay board used for in home automation? This handy device makes it easy to control multiple relays from a central controller, reducing GPIO usage and wiring complexity. - I2C expander PCF8575 drives 16 channels for load switching - Compatible with Raspberry Pi, Arduino, ESP32 at 3.3V/5V - SPDT outputs with NO/NC/Common and LED indicators
