I recently stumbled upon very small boards equipped with the ESP32-C3 chip, also called the Super Mini chip.

It's a small SBC with 4MB of flash.  They were also super cheap on AliExpress (± €9 for 5 pieces!).

I'm using the Espressif ESP-IDF framework to create, compile, flash and run small applications on this device.

Below, you will find different chapters talking about a specific property of the chip:

• The board: what's on it

• The pins: definition

• The product: details

• The Super Mini: what's available

Mostly a picture, since a picture tells a thousand words...
