The SparkFun Qwiic Quad Solid State Relay Kit uses the best solid state relays on our store and provides a single PCB to place and control up to four of them via I2C from your microcontroller. Each relay is rated to 40A @ 28-380 VAC, therefore with all four connected up you can control a lot of power very easily using Sparkfun’s Qwiic connect system. No soldering is required for this kit however you will have to attach the relays to the PCB and then connect your AC load.

An on-board 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 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 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 webstore if you are interested in these accessories.


The SparkFun Qwiic connect system is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
