Sparkfun Sparkfun COM-15093 1 pc(s) Compatible with: Arduino

Have you always wanted to control something powerful or have you ever had to turn on and off a high-performance device from your Arduino or any other low-power microcontroller? The Sparkfun Qwiic single relay offers you the most simple relay to use. The single-relay card can process up to 5.5A at 240VAC over long periods of time and allows you to control large current loads with simple I2C commands. By using our convenient Qwiic system and the integrated screw terminals, no soldering is required to connect it to the rest of your system! The Qwiic relay is supplied with a standard I2C address of 0x18, but can be changed with a simple command that allows you to control over 100 Qwiic relays on a single bus (but please note, That switching many relays on a 3.3V bus can cause voltage peaks, so that an external power supply is required)! In addition, there is an address jumper on the back of the card. By closing this jumper with solder, the address is set to 0x19. We have taken many safety precautions on the ci...
