Description
ESP32-C3-Zero (without pin header) and ESP32-C3-Zero-M (with pin header) are tiny in size with castellated holes, making them easy to integrate into other host boards. ESP32-C3-Zero comes with an onboard Type-C USB connector, which exposes most of the unused pins in a small form factor. It adopts ESP32-C3FH4 as a System-on-Chi
