SparkFun Qwiic Quad Solid State Relay Kit

The SparkFun Qwiic Quad Solid State Relay Kit takes 4 solid state relays and lets you place them on a single PCB to control all of them via I2C from your desired microcontroller. Each relay is rated to 40A @ 28-380 VAC so with all four on board you can control some serious power all from the easy-to-use Qwiic Connect System. The kit requires no soldering but there is some minor assembly required to attach the relays to the board and to connect your AC load.

The ATTiny84 on the board comes pre-programmed to accept various commands to toggle all four relays. The I2C address of the ATTiny84 is software configurable so so if you had the desire and power, you could daisy chain over 100 Qwiic Quad Relays (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, the address jumper can be opened to switch the I2C address from 0x08 (Default) to 0x09 (Alternate).

Messing with such high voltage is dangerous! This is a power accessory intended for users who are experienced around, and knowledgeable about, high AC voltage.
