Goal – What We Wanted

The qReCon Flex Raspberry Pi Relay HAT featuring user-replaceable relays for extended lifespan
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.

Design Considerations – How We Were Thinking

Infinity iconEndless Customization.
Compatible with a wide range of relay types and manufacturers for ultimate flexibility.
Replace iconBuilt for Longevity
Relays are easily replaceable, ensuring your module outlasts other fixed-relay solutions.
High-Low iconConfigurable Control Logic
Easily switch between Active High and Active Low with a simple jumper setting.
DIP switch iconFlexible GPIO Selection
Choose between two GPIO groups to best fit your project and avoid conflicts with other add-on boards.
Form iconFrom Factor
For easy assembly, qUPS has HAT form factor. Simply connect it via the 40 pin header.
Stackablility iconStackability
Pins on the connector are long ones, all can be accessed from the top of the product.
Strong iconReliable Connection
Massive, soldered pin header for power and signal connection. Pogo pins are not reliable.
Handshake iconGPIO Communication
Easy programming. Avoid extra load on capacitance limited I2C bus. 4 GPIO ports for communication.
Isolation iconOptical Isolation
Optically isolated channels safeguard your Raspberry Pi from electrical noise and damage.
Gear iconZero Firmware
Everything is done by hardware.
