IP2721: common questions

Where can I find a IP2721 reference design?

Each of the 4 boards on this page is a real design using the IP2721. 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 IP2721 use?

Most are built on ESP32 (2) and RP2040/RP2350 (1).

How big is a typical board using the IP2721?

The median is 105.5 × 56.5 mm, and 50% are two-layer designs.

What is the most popular open source board using the IP2721?

By GitHub stars, QLAMP-main by hisashin, with 24 stars.

Can I simulate one of these boards using the IP2721 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.
