SparkFun Quad Solid-State Relay Kit (Qwiic) – Sparkfun KIT-16833

The SparkFun Qwiic Quad Solid State Relay Kit uses the best solid-state relays in our store and provides a single PCB to place and control up to four of them via I2C from your microcontroller.

This kit allows you to assemble up to four of these solid-state relays on a single PCB and control them all via I2C from your favorite microcontroller. The Quad Solid State Relay Kit comes with four solid-state relays rated up to 40A at voltages between 28-380 VAC so you can switch some serious power with this board all from a single Qwiic connector attached to an Arduino or other low-powered microcontroller.

An onboard ATTiny84 comes pre-programmed for all four relays and will accept various commands to toggle them. Featuring a software configurable I2C address of the ATTiny chip, you could hook-up over 100 Qwiic Quad relays to satisfy your hunger for more power! Take note, toggling that many relays on a 3.3V bus will cause voltage spikes therefore an external power supply will be required. Furthermore, you can open the address jumper to switch the I2C address from 0x08 (Default) to 0x09 (Alternate).

Beware, tinkering with high voltages is a dangerous game. This kit is designed and intended for makers who have the experience and knowledge with a high AC voltage to operate safely. Lastly, for smaller loads (around 4-10A) air cooling will be sufficient for use but if you are running a higher load, a heatsink is a necessity. Please refer to the datasheet below for the recommended heat sink dimensions.

Note: The standoffs and 4-40 screws used in some of the photos are NOT included with the kit. Take a look at our range of standoffs and screws on the website if you are interested in these accessories.
