It is built around the Omron G6K-2F-Y DC3 dual-pole/dual-throw relay, letting a low-voltage logic system switch loads up to 1A at 30VDC or 0.3A at 125VAC at 40°C.The board offers both software and hardware control options. You can drive the relay through the on-board TCA9555 GPIO expander over I2C, or trigger it from an external input such as a physical switch or standard I/O signal.Two Qwiic connectors make it easy to add the relay to a Qwiic I2C daisy chain without soldering. The primary COM pole is available on a 3-pin screw terminal, while the secondary COM2 pole is broken out to standard 0.1-inch-spaced plated-through holes for soldered wiring or breadboard prototyping.Features:I2C Drive: Controlled via the on-board TCA9555 GPIO expander, requiring a drive current of 5.8mA at 3.3V.External Drive: Can be triggered by an external input, such as a physical switch or a standard I/O signal up to 50mA.Solderless Qwiic Integration: Two on-board Qwiic connectors allow connection to an I2C daisy chain without soldering.Dual-Circuit Control: Switches two completely independent circuits simultaneously with a single command.Signal Optimized: Engineered for lower-power signal-level switching up to 1A at 30VDC.Advanced Drive: Allows external devices to drive the relay control directly without using I2C.Specifications:Relay: G6K-2F-Y DC3 DPDT RelayLoad Limits: 1A/30VDC and 0.3A/125VACI2C Drive Current: 5.8mAExternal Drive Current: 50mARelay Connections: COM Pole and COM2 PoleCOM Pole: 3-Pin Screw TerminalCOM2 Pole: 0.1"-spaced PTHI2C GPIO Expander: TCA9555RTWR I2C GPIO ExpanderI2C Address: 0x20 (Default), 0x21 (Alternate)Qwiic Connectors: 2x Qwiic ConnectorsLEDs: Red power (PWR) LED, green status (STAT) LED, and green relay activity (ACT) LEDRed power LED: Red power (PWR) LEDGreen status LED: Green status (STAT) LEDGreen relay activity LED: Green relay activity (ACT) LEDUseful for maker and embedded projects that need isolated switching from a Qwiic-compatible controller, with support available through the SparkFun I2C Expander Arduino Library and related design files. **Product Type:** Relay Module ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD3LkCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--31ab95002b20efe05ee9711da4f2117abdb151c6/30416-Qwiic-1x1a-dpdt-relay-Feature.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD3bkCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--cc46919d654cda4c41442419a1f3e831709436a1/30416-Qwiic-1x1a-dpdt-relay-Front.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD3rkCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--25a71944161d83d29a9af62f13f9eefdd6d91dfc/30416-Qwiic-1x1a-dpdt-relay-Back.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD37kCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--ab5b7fa0d760be4f7eef78817d357d695bb50fc0/30416-Qwiic-1x1a-dpdt-relay-Scale.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
