## Description

## Meet FeatherS3[D]

FeatherS3[D] is the FeatherS3 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 16 MB of flash, 8 MB of PSRAM, two STEMMA QT connectors and the Feather format.

![Series[D] features: Both antennas. One board. · Switch in software. · Know your battery.](https://unexpectedmaker.com/images/product-content/series-d-features-feathers3d.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.
