Arduino MKR Relay Proto Shield ready-to-mount then scan your 125kHz IDThe 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
