5 open source boards using the FE1.1
Real designs built with the FE1.1, 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.

Microcontrollers on boards using the FE1.1
What boards using the FE1.1 are built for
FE1.1: common questions
Where can I find a FE1.1 reference design?
Each of the 5 boards on this page is a real design using the FE1.1. 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 FE1.1 use?
Most are built on Microchip SAM (1) and STM32 (1).
How big is a typical board using the FE1.1?
The median is 58.4 × 68.6 mm, and 40% are two-layer designs.
What is the most popular open source board using the FE1.1?
By GitHub stars, USBHub by wickerwaka, with 34 stars.
Can I simulate one of these boards using the FE1.1 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.
