Seed Studio XIAO C3 (esp32-c3)

Postby ESP32_kid » Wed Nov 12, 2025 5:50 pm

An interesting board because it has external antenna and no onboard programmable LED.
But I noticed something odd in their documentation for wifi AP, they warn that the chip can overheat hot enough to burn you. I just tested AP mode on lowest power setting 8(2dbm) (with antenna attached) and the internal temp measurement hangs around 54C in open-air.

Wondering why it runs "hot" when used in AP mode?
