Meet TinyS3[D]
TinyS3[D] is the TinyS3 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 TinyPICO-compatible footprint.
![Series[D] features: Both antennas. One board. · Switch in software. · Know your battery.](https://unexpectedmaker.com/images/product-content/series-d-features-tinys3d.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.
