2 open source boards using the 5v input
Real designs built with the 5v input, 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.

What boards using the 5v input are built for
5v input: common questions
Where can I find a 5v input reference design?
Each of the 2 boards on this page is a real design using the 5v input. 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 5v input use?
Most are built on ESP32 (1) and STM32 (1).
How big is a typical board using the 5v input?
The median is 70.8 × 103.3 mm, and 100% are two-layer designs.
What is the most popular open source board using the 5v input?
By GitHub stars, Brushless board by robotronik, with 1 stars.
Can I simulate one of these boards using the 5v input 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.
