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.
