Meet ProS3[D] - our Extremely Pro ESP32-S3 board!
ProS3[D] is the ProS3 you know, re-designed with the Series[D] upgrades: an onboard antenna and a u.FL connector on the same board, switchable from your code, an I²C fuel gauge for accurate battery monitoring & a new ultra low power 1010 Neopixel RGB LED. It keeps its USB ESD protection, castellated edges, 16 MB of flash and 8 MB of PSRAM.
![Series[D] features: Both antennas. One board. · Switch in software. · Know your battery.](https://unexpectedmaker.com/images/product-content/series-d-features-pros3d.gif)
NOTE The onboard antenna is selected by default, so you never need to worry about the RF switch being in a bad state, or the ESP32-S3 getting damaged if you forget to plug in an external antenna.
