SGP40-D-R4: common questions

Where can I find a SGP40-D-R4 reference design?

Each of the 3 boards on this page is a real design using the SGP40-D-R4. 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 SGP40-D-R4 use?

Most are built on FPGA (1) and STM32 (1).

How big is a typical board using the SGP40-D-R4?

The median is 80 × 32.5 mm, and 67% are two-layer designs.

What is the most popular open source board using the SGP40-D-R4?

By GitHub stars, LoRaDongle by marrrk, with 4 stars.

Can I simulate one of these boards using the SGP40-D-R4 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.
