## Description

![TinyC6[D] features](https://unexpectedmaker.com/images/features/main_features_tinyc6d.webp)

## Meet TinyC6[D]

TinyC6[D] is the TinyC6 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-tinyc6d.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-C6 getting damaged if you forget to plug in an external antenna.

## Shipping policy

All products purchased from this store ship directly from me here in Melbourne, Australia.
Orders are processed daily and usually go out within a few days!
I'm currently unable to ship to Germany, Denmark, or Sweden, but I am doing my best to work with Australia Post and Zonos about this issue; sorry for any inconvenience.
Finally, postage rates suck, and they keep going up; sorry :(
