2 open source boards using the LM35
Real designs built with the LM35, 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.

What boards using the LM35 are built for
LM35: common questions
Where can I find a LM35 reference design?
Each of the 2 boards on this page is a real design using the LM35. 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 LM35 use?
Most are built on RP2040/RP2350 (1) and STM32 (1).
How big is a typical board using the LM35?
The median is 95 × 72 mm, and 0% are two-layer designs.
What is the most popular open source board using the LM35?
By GitHub stars, Multislope-3I by NNNILabs, with 43 stars.
Can I simulate one of these boards using the LM35 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.
