2 open source boards using the 49E
Real designs built with the 49E, 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 49E
What boards using the 49E are built for
49E: common questions
Where can I find a 49E reference design?
Each of the 2 boards on this page is a real design using the 49E. 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 49E use?
Most are built on STM32 (1).
How big is a typical board using the 49E?
The median is 16.2 × 32.3 mm, and 100% are two-layer designs.
What is the most popular open source board using the 49E?
By GitHub stars, Amp by stustanet, with 5 stars.
Can I simulate one of these boards using the 49E 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.
