With the ESP32-C5, Espressif is bringing dual-band Wi-Fi (2.4 & 5 GHz) to a microcontroller for the first time. Espressif kindly sent me two pre-production models of the ESP32-C5-DevKitC-1 development board. I measured how the new microcontroller performs in practical tests.

The clock has been running for quite a while now without any problems. However, one small thing still bothers me. The Hall sensors tend to oscillate. Therefore, I have redesigned the electronics from scratch.
