4 open source boards using the LDO
Real designs built with the LDO, 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.

The LDO in open source designs
The gallery holds 4 open source boards using the LDO from 4 GitHub repositories; a typical one measures about 119.6 × 60.3 mm and carries around 70 components.
75% are two-layer designs, the rest use four layers or more, and 75% carry an open source license.
The most starred is Ips20 by gzweigle.
LDO: common questions
Where can I find a LDO reference design?
Each of the 4 boards on this page is a real design using the LDO. 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 LDO use?
Most are built on NXP (2) and STM32 (1).
How big is a typical board using the LDO?
The median is 119.6 × 60.3 mm, and 75% are two-layer designs.
What is the most popular open source board using the LDO?
By GitHub stars, Ips20 by gzweigle, with 60 stars.
Can I simulate one of these boards using the LDO 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.
