The MKR Relay Protoshield allows you to easily add relays to your MKR board based 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 analog 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)
