1 open source board using the LDFM
Real designs built with the LDFM, 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.
WRansohoffThe LDFM in open source designs
The gallery holds 1 open source boards using the LDFM from 1 GitHub repository; a typical one measures about 17.8 × 38.1 mm and carries around 32 components.
100% are two-layer designs, the rest use four layers or more, and 100% carry an open source license.
The most starred is STM32WB55Cx minimal by WRansohoff.
Microcontrollers on boards using the LDFM
What boards using the LDFM are built for
LDFM: common questions
Where can I find a LDFM reference design?
Each of the 1 boards on this page is a real design using the LDFM. 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 LDFM use?
Most are built on STM32 (1).
How big is a typical board using the LDFM?
The median is 17.8 × 38.1 mm, and 100% are two-layer designs.
What is the most popular open source board using the LDFM?
By GitHub stars, STM32WB55Cx minimal by WRansohoff, with 10 stars.
Can I simulate one of these boards using the LDFM 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.
