3 open source boards using the LM393N
Real designs built with the LM393N, 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 LM393N
LM393N: common questions
Where can I find a LM393N reference design?
Each of the 3 boards on this page is a real design using the LM393N. 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 LM393N use?
Most are built on ESP32 (1).
How big is a typical board using the LM393N?
The median is 100 × 100 mm, and 33% are two-layer designs.
What is the most popular open source board using the LM393N?
By GitHub stars, Qds cv by cnpem-emi, with 0 stars.
Can I simulate one of these boards using the LM393N 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.
