1 open source board using the I2C/UNIO
Real designs built with the I2C/UNIO, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.
gordosteThe I2C/UNIO in open source designs
The gallery holds 1 open source boards using the I2C/UNIO from 1 GitHub repository; a typical one measures about 158 × 100 mm and carries around 110 components.
100% are two-layer designs, the rest use four layers or more, and 100% carry an open source license.

What boards using the I2C/UNIO are built for
I2C/UNIO: common questions
Where can I find a I2C/UNIO reference design?
Each of the 1 boards on this page is a real design using the I2C/UNIO. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the I2C/UNIO use?
Most are built on PIC (1).
How big is a typical board using the I2C/UNIO?
The median is 158 × 100 mm, and 100% are two-layer designs.
What is the most popular open source board using the I2C/UNIO?
By GitHub stars, Openprog aio by gordoste, with 3 stars.
Can I simulate one of these boards using the I2C/UNIO before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
