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...
Below are the product details:
USB-C connector
WiFi
Reset and bootloader buttons
Bluetooth
Below is an explanation about the pins available on the ESP32-C3 development board.
Below is a picture showing what is available on the board: connector, buttons, chip, WiFi antenna,...
Below is an overview of the complete development board, including the accompanying headers.
The board can be powered in 3 ways:
Using the USB-C connector
Connecting +5V to the +5V pin of the board
Connecting +3V3 to the +3V3 pin of the board
So, if your board contains the correct software, you can use a +5V power supply to power the board. No need for a USB-C connector.
When the board is powered with +5V you also have +3V3 at the 3V3 pin.
Note: you CAN NOT have both USB-C as well as +5V connected at the same time!
This will send your board to the happy hunting grounds...
