TinyPICO[D] is a tiny ESP32 board with switchable onboard and u.FL antennas, an I²C battery fuel gauge and LiPo charging, in the original TinyPICO footprint.
It’s the TinyPICO you know, re-designed with all the latest Series[D] upgrades and a new ultra low power 1010 Neopixel RGB LED.
![TinyPICO[D] features](https://cdn.shopify.com/s/files/1/0174/1800/files/TinyPICO_D__Features.webp?v=1793118333)
Both antennas. One board.
TinyPICO[D] has both an onboard antenna and a u.FL connector for an external antenna, so there’s no separate version to choose. You can switch between them on the fly from inside your code, and the onboard antenna is selected by default, so the ESP32 is safe even without an external antenna plugged in.
Know your battery.
An I²C fuel gauge for battery monitoring, plus onboard LiPo charging.
TinyPICO[D] uses the CH9102F Serial2UART chip instead of the CP2104. If you are using Windows or macOS, you will need to install the driver to be able to access the TinyPICO via USB.
