Summary of RelayFi ESP32-WROOM 4 channel relay board
The RelayFi is a 4-channel smart relay board powered by an ESP32-WROOM, enabling safe control of up to four devices at 110-250 VAC or 30 VDC. It features photo-coupling isolation via optocouplers and supports Wi-Fi connectivity for integration with Raspberry Pi, Pico W, and voice-controlled smart home systems. The board uses the Arduino IDE for programming via a micro USB port and operates efficiently with low power consumption of 60 milli-amperes.
Parts used in the RelayFi:
- ESP32 WROOM
- 4 Channel Smart Relay Board
- Optocoupler
- Micro USB Port
- I2c Pins
- Standard Component Pins
Hobbyists, electronic enthusiasts and makers may be interested in a new 4 channel relay board aptly named the RelayFi. The 4 channel smart relay board is powered by a ESP32 WROOM providing the ability to safely control up to four appliances or devices on a load of 110-250 VAC/7A, 30 VDC/10A depending on your needs. If you are interested in learning more about the relay board I would recommend jumping over to the official Raspberry Pi MagPi website where the team have carried out a review of the board explaining a little more about what it can be used for and its construction.
7/10 A solid IoT board with easy programming functions that can interact with Raspberry Pi just fine.
MagPi Magazine :
“With a series of I2c and standard component pins, you can add a little extra control to the board that is all programmed using the classic Arduino IDE. As it’s all Wi-Fi connected, having it talk to a Raspberry Pi or Pico W is a matter of making sure it’s looking for the right thing. Like an Arduino board, a micro USB port is used to power and connect to it for programming, which also supports various smart home systems for voice control via RelayFi. It’s a fairly solid build for such a relatively cheap board, and the ease of coding helps with its appeal as well.”
