Most are built on ESP32 (1).
How big is a typical board using the SCD40-D-R2?
The median is 90 × 52.5 mm, and 50% are two-layer designs.
What is the most popular open source board using the SCD40-D-R2?
By GitHub stars, OpenAirScope by emertcakir, with 26 stars.
Can I simulate one of these boards using the SCD40-D-R2 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.
