Taking a look at the board, the Quad Relay has four individual relays rated up to 5 Amps per channel at 250VAC or 30VDC. Each channel also has its own uniquely coloured LED, silk for easy identification, and screw terminals for optional connection. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system!\u003c\/p\u003e\n\u003cp\u003eAt the heart of the SparkFun Qwiic Quad Relay is an ATtiny84 that takes various commands to toggle the four relays. The I\u003csup\u003e2\u003c\/sup\u003eC address of the ATtiny84A is software configurable so if you had the desire and power, you could daisy chain over 100 Qwiic Quad Relays. There is also a header that breaks out the four I\u003csup\u003e2\u003c\/sup\u003eC lines if you're not taking advantage of the Qwiic connectors. And last up, the barrel jack is rated for wall adapters in the range 7-12V but we have equipped this relay board with a jumper on the underside of the board if you want to use wall adapters at 5V.\u003c\/p\u003e\n\u003cp\u003eMessing with such high voltage is dangerous! We've included many safety precautions onto the PCB including, wide traces designed for high amperage, ground isolation between the relay and other circuitry, and a milled out area around the common pin of the relay. However, with all the safety precautions included with the SparkFun Qwiic Quad Relay, this is still a power accessory for users who are experienced around, and knowledgeable about high AC voltage. If that's not quite your jam, that's okay! Check out the IoT Power Relay, instead, to start learning how to use power relays easily!\u003c\/p\u003e\n\u003cp\u003eGet Started with the Sparkfun Qwiic Quad Relay Guide\u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/XL7Gu8KlnPI?si=b8eHTOsRtJuf1_Ez\u0026amp;start=40\" height=\"315\" width=\"560\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cdiv class=\"center-block text-center\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cdiv role=\"tabpanel\" class=\"tab-pane fade\" id=\"features-tab\"\u003e\n\u003cdiv class=\"col-sm-12\"\u003e\n\u003cul\u003e\n\u003cli\u003eFour JZC-11F Relays\n\u003cul\u003e\n\u003cli\u003e5A at 250VAC, 30VDC\u003c\/li\u003e\n\u003cli\u003eEach relay has its own coloured LED and silk labels for easy identification.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eSafety Features\n\u003cul\u003e\n\u003cli\u003eGround pour isolated from relays.\u003c\/li\u003e\n\u003cli\u003eAir gap around the common pin on the relays.\u003c\/li\u003e\n\u003cli\u003eLarge trace width on relay pins far exceeding the peak 5A current.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eATtiny84A\n\u003cul\u003e\n\u003cli\u003eI\u003csup\u003e2\u003c\/sup\u003eC commands for toggling individual relays or all the relays at once.\u003c\/li\u003e\n\u003cli\u003eI\u003csup\u003e2\u003c\/sup\u003eC commands for turning all relays off or on.\u003c\/li\u003e\n\u003cli\u003eTwo I\u003csup\u003e2\u003c\/sup\u003eC addresses\n\u003cul\u003e\n\u003cli\u003e0x6D (Default)\u003c\/li\u003e\n\u003cli\u003e0x6C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eI\u003csup\u003e2\u003c\/sup\u003eC address is software configurable.\u003c\/li\u003e\n\u003cli\u003eAll commands are listed in the example code.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eScrew Terminals\n\u003cul\u003e\n\u003cli\u003e26-14 Gauge AWG wire\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003ePower\n\u003cul\u003e\n\u003cli\u003eMax Current Draw ~250mA\u003c\/li\u003e\n\u003cli\u003eVin via Barrel Jack\n\u003cul\u003e\n\u003cli\u003e7V to 12V\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eVin via Barrel Jack w\/ Bypass Jumper Closed\n\u003cul\u003e\n\u003cli\u003e5V\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"alert alert-info\"\u003e\n\u003ch2\u003eRevision Changes\u003c\/h2\u003e\n\u003cp\u003eThe latest revision includes the following updates:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIncluded a normally closed jumper for the power LED.\u003c\/li\u003e\n\u003cli\u003eSwitching regulator in place of a linear regulator.\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003eThe switching regulator is much more efficient; no external cooling needed when powering four relays at once.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003eImproved circuitry around the relays.\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003eAn issue where relays on certain boards in v1.0 didn't switch completely when actuated has been resolved.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cdiv role=\"tabpanel\" class=\"tab-pane fade\" id=\"documents-tab\"\u003e\n\u003cdiv class=\"col-sm-12\"\u003e\n\u003cul\u003e\n\u003cli\u003eSchematic\u003c\/li\u003e\n\u003cli\u003eEagle Files\u003c\/li\u003e\n\u003cli\u003eBoard Dimensions\u003c\/li\u003e\n\u003cli\u003eHookup Guide\u003c\/li\u003e\n\u003cli\u003e\nDatasheet (JZC-11F)\u003c\/li\u003e\n\u003cli\u003eQwiic Page\u003c\/li\u003e\n\u003cli\u003e\nArduino Library\n\u003cul\u003e\n\u003cli\u003eExample Code\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\nGitHub\n\u003cul\u003e\n\u003cli\u003eDefault Firmware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":46375208157241,"sku":"jar1787258200839","price":18.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0795\/9176\/8121\/files\/sparkfun-qwiic-quad-relay_1.jpg?v=1787258209","url":"https:\/\/myoutfitstore.shop\/products\/sparkfun-qwiic-quad-relay","provider":"My Store","version":"1.0","type":"link"}
