SparkFun Qwiic Relay - 1x1A DPDT

Easily control high-power devices directly from your microcontroller via I2C with the SparkFun Qwiic Relay. Built around the Omron G6K-2F-Y DC3 dual-pole/dual-throw (DPDT) relay this board allows you to safely switch loads up to 1A at 30VDC or 0.3A at 125VAC (at 40 C). This relay is perfect if you're controlling heavy-duty motors or managing other high-power devices bridging the gap between low-voltage logic and high-power applications.Flexible Control OptionsWe designed this board to adapt to your specific project needs offering multiple ways to trigger the relay:I2C Drive: Controlled via the on-board TCA9555 GPIO expander requiring a remarkably low drive current of just 5.8mA at 3.3V.External Drive: This relay can also be triggered by an external input such as a physical switch or a standard I/O signal (up to 50mA) giving you hardware-level control.Solderless Qwiic Integration: Two on-board Qwiic connectors let you add the relay to your I2C daisy chain without ever touching a soldering iron.Transitioning from a Single RelayIf you are upgrading from our original Qwiic Single Relay this DPDT version introduces a few key architectural differences that have been tailored for precision control:Dual-Circuit Control: While the original relay used a single-pole (SPDT) design this DPDT board can switch two completely independent circuits simultaneously with a single command.Signal Optimized: The original relay was primarily built for heavy high-voltage AC loads up to 5.5A at 240VAC. This new DPDT version is specifically engineered for lower-power signal-level switching up to 1A at 30VDC.Advanced Drive: Don't want to use I2C? This board allows external devices to drive the relay control directly.Wiring your high-power components is as straightforward as it gets with the Qwiic Relay. We included a 3-pin screw terminal for a quick completely solderless connection to the relay's primary pole (COM Pole). Meanwhile the secondary pole (COM2 Pole) is broken out to standard 0.1-inch-spaced plated-through holes (PTH) giving you the flexibility to solder wires directly or use a breadboard for prototyping.
