Arduino 4 Relays Shield is a solution for driving high power loads that cannot be controlled by Arduino's digital IOs, due to the current and voltage limits of the controller.
The Shield features four relays, each relay provides 2 pole changeover contacts (NO and NC); in order to increase the current limit of each output the 2 changeover contacts have been put in parallel. Four LEDs indicate the on/off state of each relay.


  • Operating Voltage:5 V
  • Current needs:140 mA (with all releays on, about 35 mA each)
  • PCB size:53 x 68.5 mm
  • Weight:0.044 Kg


  • Thinker Kit interface:2x TWI, 2x OUT, 2x IN
  • Interfaces with Arduino Board:DIO
  • Relays:4 (60W)
