Which microcontrollers do boards using the V4220M use?
Most are built on ESP32 (1) and STM32 (1).
How big is a typical board using the V4220M?
The median is 52.7 × 58 mm, and 50% are two-layer designs.
What is the most popular open source board using the V4220M?
By GitHub stars, OwmBoard by kanengomibako, with 11 stars.
Can I simulate one of these boards using the V4220M 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.
