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).

Turn on and off lamps, fans, solenoids, and other small appliances(up to 250VAC or DC power) using any Feather board.
Compared to Adafruit's smaller Relay FeatherWings, this can handle a beefy 1200 Watts.
Works with all/any of our Feather boards, just wire up the relay control pin to whatever GPIO you like.
Connect a FeatherWing on top of your Feather board with Feather Stacking Headers or Feather Female Headers.

Fault-Tolerant Design: Fault Tolerant Design, Even if the Control Line is Broken, the Relay will not Operate.
All Interfaces of Relay can be Wired Out Through the Terminals Directly,Normally Open and Normally Closed.
Optocoupler Isolation:1 Channel Relay Board use Optocoupler Isolation that has Strong Driving Ability and Stable Performance ,The Isolation Circuit Prevent Damages to I / O Port by Relay Switch Current.
Jumper Design: The Relay Module has a Jumper That You Can Set Rather the Unit State Changes with High or Low Signal. Has Screw Terminals for Relay (NC,C,NO) and for Input.
Wide Application: DC 5V Relay Module Works Well with ARM /PIC /AVR /MCU/Raspberry/CNC Machine/ PS4 etc..
