SE555: common questions
Where can I find a SE555 reference design?
Each of the 2 boards on this page is a real design using the SE555. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
How big is a typical board using the SE555?
The median is 85.1 × 62.2 mm, and 100% are two-layer designs.
What is the most popular open source board using the SE555?
By GitHub stars, TSAL(1) by formulaslug, with 2 stars.
Can I simulate one of these boards using the SE555 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.
