The Grove - 4-Channel SPDT Relay has four single pole - double throw (SPDT) switches. It only requires low-voltage and low current signals to control the switches, specifically, you can use 5V DC to control max 250V AC or 110V DC.
They have used an onboard STM32F030F4P6 to control the channels separately. The control commands are transmitted via the I2C interface, the on-board STM32F030F4P6 will parse the command so that you can control the switch you want.
Some applications of this relay are:
- Domestic appliances
- Office machines
- Remote control TV receiver
- Monitor displays
- Audio equipment
- High rushing current use applications
- Dimensions: 120mm x 60mm x 19mm
- High temperature resistant plastic shell
- High voltage loads
- Low power consumption
- Long lasting
- 128 Optional I2C address
