What boards using the SCD41 are built for
SCD41: common questions
Where can I find a SCD41 reference design?
Each of the 2 boards on this page is a real design using the SCD41. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the SCD41 use?
Most are built on ESP32 (1) and RP2040/RP2350 (1).
How big is a typical board using the SCD41?
The median is 50.8 × 45 mm, and 0% are two-layer designs.
What is the most popular open source board using the SCD41?
By GitHub stars, Air quality sensor by roepkefeller, with 58 stars.
Can I simulate one of these boards using the SCD41 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.
