What boards using the LM75B are built for
LM75B: common questions
Where can I find a LM75B reference design?
Each of the 9 boards on this page is a real design using the LM75B. 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 LM75B use?
Most are built on ESP32 (3), ESP8266 (1) and STM32 (1).
How big is a typical board using the LM75B?
The median is 50 × 56.3 mm, and 38% are two-layer designs.
What is the most popular open source board using the LM75B?
By GitHub stars, OtterCastAmp by Ottercast, with 341 stars.
Can I simulate one of these boards using the LM75B 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.
