Drive your light bulbs, AC motor, fans, grow lamps, heaters, etc.
Input: 220VAC (can be used at 120VAC mains but requires changing 4 resistors, technical support provided)
Outputs: 4 x 220VAC
True HATs have an 24C32 EEPROM, which auto-configures the RPi GPIO ports at boot time.
The TRIAC is a solid state device, capable of switching on-off hundreds of times per second, without any wear or noise. In addition, the board has opto-isolators, providing full isolation between DC and AC stage.
BEGINNERS: simply write 1 or 0 to the corresponding GPIO port to turn the AC channel on / off.
ADVANCED: Opto-TRIAC board has an AC phase-feedback GPIO port that feeds the phase of the alternating signal, therefore through a Kernel module driver, it is possible to control the TRIAC trigger phase, with a +/-1° accuracy. This way, it is possible to dim the output, and control both RMS and mean value.
Open source driver available on GitHub. I also have some Youtube videos showing usage examples.
Not included: - Raspberry Pi
ATTENTION: the HAT provides a safe galvanic isolation between DC and AC stage, however improper mounting can cause serious injuries or death. Seller is not responsible for any damage.
