6 open source boards using the LM555xM
Real designs built with the LM555xM, 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 LM555xM
What boards using the LM555xM are built for
LM555xM: common questions
Where can I find a LM555xM reference design?
Each of the 6 boards on this page is a real design using the LM555xM. 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 LM555xM use?
Most are built on NXP (1).
How big is a typical board using the LM555xM?
The median is 67 × 72.1 mm, and 83% are two-layer designs.
What is the most popular open source board using the LM555xM?
By GitHub stars, Spike n hold by BeeHive-org, with 13 stars.
Can I simulate one of these boards using the LM555xM 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.
