Description

This is a ready breakout board with two 5V activated relays (3.3V compatible), and the signal is optoisolated, it is protected :) Easy to use and suitable for beginners, and of course students too. You can check out the tutorial by baelza.bubba in Instructables:

If you need to control AC or high current, high voltage load, this will be the perfect board.

Warranty Period: 12 months
Features
  • 5VDC two channels relay interface board
  • From our tests, the control signal is 3.3V compatible, yet the VCC needs to be 5VDC. So you can use Raspberry Pi's GPIO to activate or deactivate the relay.
  • Active Low configuration
  • Signal Indicator LED for each Relay
  • Relay Maximum Current Rating: 10A
  • Relay Maximum Voltage Rating: AC 250V / DC 30V
  • Can control various appliances with large current and high voltage
  • Can be controlled directly by microcontrollers such as Arduino, 8051, AVR, PIC, DSP and ARM
  • Build-in 2 units of Opto-Isolator IC 817C
