What is it?

Unlock your Raspberry Pi's potential with this robust 4-channel relay module. Featuring premium Schrack relays, optical isolation, and configurable GPIOs and Active High and Active Low control, it gives you the confidence and reliability your projects deserve.

Why did you make it?

Our goal with the qRecon was to create a professional-grade relay module that puts safety and reliability first. We noticed that many existing solutions lack the features needed for demanding projects. We built it to be a robust and flexible tool that you can rely on to control high-power devices with absolute confidence, providing the peace of mind that comes with a truly trusted solution.

What makes it special?

For easy assembly, qUPS has HAT form factor. Simply connect it via the 40 pin header.

Pins on the connector are long ones, all can be accessed from the top of the product.

Massive, soldered pin header for power and signal connection. Pogo pins are not reliable.

Everything is done by hardware.

Easy programming. Avoid extra load on capacitance limited I2C bus. 4 GPIO ports for communication.

Optically isolated channels safeguard your Raspberry Pi from electrical noise and damage.

A dedicated LED shows the real-time ON/OFF status of each relay.

Each relay features both Normally Open (NO) and Normally Closed (NC) contacts, letting you choose how to control your circuits.

Easily switch between Active High and Active Low with a simple jumper setting.

Choose between two GPIO groups to best fit your project and avoid conflicts with other add-on boards.
