Waveshare 17852 2-CH TRIAC HAT
Description
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
Features at a glance
- 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
