Microcontrollers on boards using the LM555CMX/NOPB

LM555CMX/NOPB: common questions

Where can I find a LM555CMX/NOPB reference design?

Each of the 2 boards on this page is a real design using the LM555CMX/NOPB. 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 LM555CMX/NOPB use?

Most are built on STM32 (1).

How big is a typical board using the LM555CMX/NOPB?

The median is 118.9 × 87.1 mm, and 50% are two-layer designs.

What is the most popular open source board using the LM555CMX/NOPB?

By GitHub stars, VCU by formulaslug, with 7 stars.

Can I simulate one of these boards using the LM555CMX/NOPB 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.
