What boards using the HDC1080 are built for

HDC1080: common questions

Where can I find a HDC1080 reference design?

Each of the 7 boards on this page is a real design using the HDC1080. 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 HDC1080 use?

Most are built on ESP32 (2), STM32 (2), AVR/Arduino (1) and RP2040/RP2350 (1).

How big is a typical board using the HDC1080?

The median is 93 × 100 mm, and 57% are two-layer designs.

What is the most popular open source board using the HDC1080?

By GitHub stars, Tiny sensor by larry-wong, with 34 stars.

Can I simulate one of these boards using the HDC1080 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.
