It is easy to use, works great with ESPHome, and is a must-have for any maker or developer. 5/5 – Highly Recommended for IoT & DIY Enthusiasts!

Nonostante abbia pochi ingressi, è utilissimo in progetti che prevedano un uso con batteria, perché può gestire una LiPo senza altre schede aggiuntive. Questo per una scheda davvero micro è un grosso vantaggio.

So I built a windvane / anemometer for my sailboat using a standard esp32. It worked well, but I couldn't help but focus on the size of the esp32 as I wanted to fit this microcontroller into my project. After some searching I came across this Seed Studio Xiao esp32c3 and gave it a try. It passed all its tests and I am happily using this on my sailboat. You might not have as many IO pins as a full size esp32, but if your projects don't require that many, your in luck. The wifi antenna that comes with this seems to have better range the the stock antenna on a standard esp32.
