What boards using the AP3211K are built for
AP3211K: common questions
Where can I find a AP3211K reference design?
Each of the 2 boards on this page is a real design using the AP3211K. 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 AP3211K use?
Most are built on ESP32 (1) and STM32 (1).
How big is a typical board using the AP3211K?
The median is 93 × 33 mm, and 0% are two-layer designs.
What is the most popular open source board using the AP3211K?
By GitHub stars, Transponder-11.9.1 by peterantypas, with 444 stars.
Can I simulate one of these boards using the AP3211K 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.
