Which microcontrollers do boards using the SGP40 use?
Most are built on ESP32 (3).
How big is a typical board using the SGP40?
The median is 67.8 × 58.2 mm, and 100% are two-layer designs.
What is the most popular open source board using the SGP40?
By GitHub stars, ClimateSprinklerController by kbx81, with 54 stars.
Can I simulate one of these boards using the SGP40 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.
