3 open source boards using the SHT21
Real designs built with the SHT21, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

What boards using the SHT21 are built for
SHT21: common questions
Where can I find a SHT21 reference design?
Each of the 3 boards on this page is a real design using the SHT21. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
How big is a typical board using the SHT21?
The median is 11.1 × 17.4 mm, and 100% are two-layer designs.
What is the most popular open source board using the SHT21?
By GitHub stars, I2c sensors another by GNB-UAM, with 4 stars.
Can I simulate one of these boards using the SHT21 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.
