ProS3[D] ESP32-S3 Development Board by Unexpected Maker

Introducing the ProS3[D] - The Ultimate Pro ESP32-S3 Development Board designed by Unexpected Maker.

This board features two antenna options on a single board: an onboard antenna and a u.FL connector for an external antenna. You can switch between the antennas on the fly via an RF switch programmatically in your code. The onboard antenna is selected by default to prevent any damage or issues when no external antenna is plugged in.

The ProS3[D] supports multiple environments including CircuitPython (updatable from circuitpython.org), Arduino 2.0.3 or later with S3 support, ESP-IDF, and an early MicroPython port.
