Microcontrollers on boards using the LR4054
LR4054: common questions
Where can I find a LR4054 reference design?
Each of the 3 boards on this page is a real design using the LR4054. 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 LR4054 use?
Most are built on STM32 (3).
How big is a typical board using the LR4054?
The median is 51.3 × 47.5 mm, and 100% are two-layer designs.
What is the most popular open source board using the LR4054?
By GitHub stars, Class 2a by rmd6502, with 0 stars.
Can I simulate one of these boards using the LR4054 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.
