SparkFun Qwiic Relay - 1x1A DPDT

Effortlessly control high-power devices directly from your microcontroller via I2C with the SparkFun Qwiic Relay. This board, featuring the Omron G6K-2F-Y DC3 dual-pole/dual-throw (DPDT) relay, allows for safe switching of loads up to 1A at 30VDC or 0.3A at 125VAC at 40°C. Ideal for managing heavy-duty motors or other high-power applications, it bridges the gap between low-voltage logic and high-power demands.

Imagine the convenience of controlling high-power devices like industrial motors or lighting systems with just a microcontroller. This relay makes it possible by offering flexible control options. Whether using the I2C drive via the on-board TCA9555 GPIO expander with a minimal current of 5.8mA at 3.3V or opting for an external drive with up to 50mA, you have the freedom to choose how you trigger the relay. The solderless Qwiic integration further simplifies adding the relay to your I2C daisy chain.

Upgrading from a single relay setup? This DPDT version introduces dual-circuit control, allowing you to switch two independent circuits simultaneously with a single command. Unlike the original single-pole design, this relay is tailored for precision control of lower-power signal-level switching up to 1A at 30VDC. For those who prefer not to use I2C, the board supports direct control by external devices.

Connecting your high-power components is straightforward with the included 3-pin screw terminal for a completely solderless connection to the relay's primary pole. The secondary pole is accessible via standard 2.54mm-spaced plated-through holes, offering the flexibility to solder wires directly or use a breadboard for prototyping. This design ensures a seamless integration into your projects, making complex wiring tasks a thing of the past.
