Raspberry Pi 2-CH Triac HAT expansion board (17852)

Dual Channels Bidirectional Triac HAT for Raspberry Pi, Integrated MCU, Commands Control, UART / I2C - a two-channel expansion board designed for Raspberry Pi and intended for industrial control systems (control of pumps, valves, etc. industrial systems), in smart agricultural and livestock systems (control of ventilation of greenhouses and barns, control of light, water supply, feeding systems, drives of other systems, etc.

This board has the following advantages over relays:

high efficiency + no noise or wear + fast response + contactless switching + adjustable power

Designed for the Raspberry Pi and has a standard Raspberry Pi 40PIN GPIO connector customized for the Raspberry Pi series boards:

FEATURES:

• STM32F0 MCU controller requires minimal Raspberry Pi resource, UART/I2C communication
• RC damping circuit protects the triac from power fluctuations
• Output power up to 4400 W under ideal heat dissipation conditions
• Optocoupler isolation to prevent interference from high-voltage circuit
• Indicator for easy checking of the triac status
• Reserved UART and I2C interface for work with other control boards
• Data transfer rate: up to 921.6 kbps for UART, up to 1024 kbps for I2C
• Comes with development resources and manual (C and Python examples)

The built-in STM32F030 microcontroller supports direct command control, is easy to develop, has a fast response and requires minimal resources from the Raspberry Pi:

High data transfer rate: up to 921.6 kbps for UART, up to 1024 kbps for I2C:

Output power up to 4400 W under ideal heat dissipation conditions:

Opto-isolated solution that prevents interference in the high voltage circuit:

Example of controlling the operation of 220VAC household appliances:
