SparkFun Qwiic Single Relay-Up to 5.5A at 240VAC Multiple I2C addresses Available Turn on/Off high Power Device from Low Power microcontroller No Soldering Large Power Loads w/Simple I2C Commands

Have you ever wanted to control something powerful or have you ever needed to turn on/off a high power device from your Arduino compatible board or another low powered microcontroller? No soldering needed to get started. Plug and play. Code available. Small footprint..
The Single Relay board can handle up to 5.5A at 240VAC for long periods of time and allows you to control large power loads with simple I2C commands. Utilizing our handy Qwiic system, and on-board screw terminals, no soldering is required to connect it to the rest of your system!.
The Qwiic Relay comes with a default I2C address of 0x18 but can be changed with a simple command allowing you to control over 100 Qwiic Relays on a single bus (but please be aware that toggling lots of relays on a 3.3V bus can cause voltage spikes so an external power supply will be required)!.
In addition, there is an address jumper on the back of the board. Closing this jumper with solder will change the address to 0x19..
Operating Voltage: 1.7V-3.6V. Coil Resistance: 23.5Ω. I2C Address: 0x18 (Default), (Jumper changes to 0x19). Max Current (Through Relay): 5.5A (240 VAC).
