Which microcontrollers do boards using the ESP-WROOM-02U use?
Most are built on ESP32 (4).
How big is a typical board using the ESP-WROOM-02U?
The median is 86 × 90 mm, and 75% are two-layer designs.
What is the most popular open source board using the ESP-WROOM-02U?
By GitHub stars, Deauther andromeda by SpacehuhnTech, with 32 stars.
Can I simulate one of these boards using the ESP-WROOM-02U 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.
