3 open source boards using the LM258
Real designs built with the LM258, 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.

LM258: common questions
Where can I find a LM258 reference design?
Each of the 3 boards on this page is a real design using the LM258. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
What parts are used alongside the LM258?
The 24AA01, AP2210-3.3, AZ1117, LM5107 and MP2459 appear in the most repositories here.
Which microcontrollers do boards using the LM258 use?
Most are built on STM32 (2).
How big is a typical board using the LM258?
The median is 114.5 × 60.5 mm, and 100% are two-layer designs.
What is the most popular open source board using the LM258?
By GitHub stars, Mppt-2420-lc by LibreSolar, with 233 stars.
Can I simulate one of these boards using the LM258 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.
