SparkFun Qwiic Quad Solid State Relay Kit



Description Attachments

The SparkFun Qwiic Quad Solid State Relay Kit is an innovative product that allows you to control up to four solid state relays on a single PCB via I2C from your chosen microcontroller. Each relay can handle up to 40A @ 28-380 VAC, meaning you can control a significant amount of power through the user-friendly Qwiic Connect System. The kit is designed for easy assembly, with no soldering required.

The product features an ATTiny84 on the board that comes pre-programmed to accept various commands for toggling all four relays. The I2C address of the ATTiny84 is software configurable, allowing for the potential to daisy chain over 100 Qwiic Quad Relays. However, handling many relays on a 3.3V bus can cause voltage spikes, so an external power supply may be necessary. The address jumper can also be opened to switch the I2C address from 0x08 (Default) to 0x09 (Alternate).

While the SparkFun Qwiic Quad Solid State Relay Kit allows for high voltage control, it's important to note that working with such voltage can be dangerous. This product is intended for users who are experienced and knowledgeable about high AC voltage. If dealing with high AC voltage is not within your comfort zone, consider the IoT Power Relay, which is fully enclosed for safer use. For small loads (eg. 4-10A), air cooling should be sufficient, but for more than that, a heat sink is recommended. The relay datasheet provides recommended heat sink dimensions.

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.

The kit includes: 1x Qwiic Quad Solid State PCB, 4x Solid State Relay - 40A (3-32V DC Input), 8x 4-40 Hex Nut, 8x 3/8in. Phillips Machine Screw - 4-40 Thread, and 1x Pre-stripped Wires 2" - 24AWG - 8 pack.

Key features include: Operating Voltage: 2.5-3.6V (3.3V recommended), I2C Address: 0x08 (Default), 0x09 (Alternate via jumper), Max Current (Through Relay): 40A (24-380VAC), Zero Cross Trigger, and Normally Open Circuit Only.
