Dual Channels Bidirectional Triac HAT For Raspberry Pi, Integrated MCU, Commands Control, UART / I2C

Dual Channels Triac HAT

Bidirectional SCR Isolated HAT, Dual Channels Triac Output Control

Designed for Raspberry Pi 

Advantages Over Relay

High Efficiency, No Mechanical Noise Or Wear, Quick Response, Adjustable Output


Designed For Raspberry Pi Series

Standard Raspberry Pi 40PIN GPIO Header, Customized For Raspberry Pi Series Boards


  • STM32F0 MCU controller, requires minimal Raspberry Pi resource, UART / I2C communication
  • RC snubber circuit, protect the triac from power fluctuation
  • Up to 4400W output power, under ideal heat dissipation condition
  • Optocoupler isolation, preventing interference from the high voltage circuit
  • Indicator for easy checking the status of triac
  • Reserved UART and I2C interface, for working with other host control boards
  • Data rate: up to 921.6kbps for UART,up to 1024kbps for I2C
  • Comes with development resources and manual (examples in C and Python)
