Microcontrollers on boards using the TPA321
TPA321: common questions
Where can I find a TPA321 reference design?
Each of the 1 boards on this page is a real design using the TPA321. 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 TPA321 use?
Most are built on RP2040/RP2350 (1).
How big is a typical board using the TPA321?
The median is 14 × 1 mm, and 100% are two-layer designs.
What is the most popular open source board using the TPA321?
By GitHub stars, Vectorscope GuyFawkes by shabaz123, with 3 stars.
Can I simulate one of these boards using the TPA321 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.
