Arduino MKR Relay Proto Shield Brand_Anidees I²CDriver comes with free (asThe 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.
