2-CH Triac Dimmer HAT for Raspberry Pi, Integrated MCU, UART / I2C

This is a Bidirectional SCR Isolated HAT, Dual Channels Triac Output Control, ideal for lighting and industrial motor automation projects. This includes smart lighting, controlling motors for things such as ventilation, pump control, valve control, heating and air conditioning systems etc.. Basically anything that runs on mains A/C power, either through a switch or variable voltage/current control.

This device has some advantages over a traditional relay since is offers higher efficiency, no mechanical wear, along with quicker response and adjustable outputs.

Key Features

• 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)

When connecting this to your Raspberry Pi, or Jetson Nano development board (this board uses the RPI standard 40pin GPIO header), you can easily interface high voltage devices such as hosehold lighting, or industrial pumps/motors to your automation project.
