Arduino MKR Relay Proto Shield

The MKR Relay Proto Shield allows you to easily command relays with your MKR board. The shield provides two onboard relays and a small prototyping area if you need to add some other component to your project.

The shield provides two relays (Datasheet) called RELAY1 and RELAY2 commanded by pin 1 and pin 2 respectively.

The shield also provides an easy connection by means of screw terminal blocks to A1 to A4 analogue inputs, I2C and supply voltages.

• Operating voltage 3.3V (supplied from the host board)
• Two relays with NO, COM and NC connections
• Works with battery-powered board
• 8 positions screw terminal blocks for easy connections with A1 to A4 Analog input, SCL SDA for I2C, GND and 3.3V output
• 6 positions screw terminal blocks (NO, COM, NC for each relay)
• Carry current: 2 A
• Max. operating voltage: 24 VAC, 50 VDC
• Max. operating current: 1 A
• Max. switching capacity: 62.50 VA, 30W
• Proto area
