ACT4088: common questions
Where can I find a ACT4088 reference design?
Each of the 8 boards on this page is a real design using the ACT4088. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
What parts are used alongside the ACT4088?
The IRAM256a, LM358, lnk304D, non_plated and SI8621 appear in the most repositories here.
Which microcontrollers do boards using the ACT4088 use?
Most are built on STM32 (6) and AVR/Arduino (1).
How big is a typical board using the ACT4088?
The median is 100 × 100 mm, and 75% are two-layer designs.
What is the most popular open source board using the ACT4088?
By GitHub stars, Stmbl 4.0 by rene-dev, with 979 stars.
Can I simulate one of these boards using the ACT4088 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.
