SparkFun_Qwiic_Relay_Line

The SparkFun Qwiic Relay Line are a series of Qwiic compatible boards to control high power devices from a microcontroller over I²C using the Qwiic interface.

The SparkFun Qwiic Relay - 1X1A DPDT lets you control high power devices from a microcontroller over I²C. This relay breakout uses the G6K-2F-Y DC3 dual-pole/dual-throw relay from Omron Electronic Components capable of switching loads of 1A/30VDC and 0.3A/125VAC (at 40°C) with very low drive currents to switch the relay. This board has one 3-pin screw terminal connector for solderless connection to one of the relay's terminals and a 0.1"-spaced plated through-hole header for connecting the second terminal. It also has options to drive the relay over I²C (via Qwiic or a soldered connection) or an external drive input such as a switch or I/O signal. Driving the relay over I²C only requires up to [email protected] and driving it from an external input requires up to [email protected].
