L5973D: common questions
Where can I find a L5973D reference design?
Each of the 2 boards on this page is a real design using the L5973D. 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 L5973D use?
Most are built on ESP32 (1) and STM32 (1).
How big is a typical board using the L5973D?
The median is 126.6 × 69.3 mm, and 0% are two-layer designs.
What is the most popular open source board using the L5973D?
By GitHub stars, Lboard2 by electrodyssey, with 7 stars.
Can I simulate one of these boards using the L5973D 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.
