The ESP32 C3 Nano is an Arduino Nano compatible development board, designed to provide enhanced computing power, wireless connectivity, addressable LED capabilities, and a built-in programming and debugging interface.
|
|
|
|
It is based on the ESP32 C3 chip, which provides improved processing capabilities, increased memory, and wireless connectivity compared to traditional Atmega variant.
|
|
|
|
The board maintains compatibility with the Arduino Nano form factor, ensuring easy integration into existing projects and making it a drop-in replacement for the traditional Arduino Nano board.

## ESP32-C3
|
|
|
|
ESP32-C3 is an entry-level 32-bit MCU in the ESP32 line. Generally they offer similar feature set compared to other ESP32 chips, but designed to be low-cost from the start, including popular communication interfaces, low power consumption in sleep mode (down to few micro-amps) and ease of use.

## How to programm
|
|
|
|
To program the ESP32-C3 microcontroller, you may use either Serial upload method or USB Upload. ESP32-C3 Development Board uses USB Upload method.
|
|
|
|
You need to connect USB-C cable, it will be used to power the board, flash over USB, serial over USB and JTAG over USB
|
|
|
|
### Arduino IDE
|
|
|
|
Add [https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json](https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json) to the board manager
|
|
|
|
|
|
|
|
After that you should install **ESP32 by Espressif Systems** from Board Manager
|
|
|
|
|
|
|
|
Select **ESP32 C3 Dev Board** as target and other necessary settings in the board settings after
|
|
|
|
|
|
|
|
Next press Build or Upload button, it should just work (RGB LED will blik white with blinky example)
|
|
|
|
|
|
|
|
### Platformio IDE
|
|
|
|
After installing [Plarformio IDE](https://platformio.org/platformio-ide), open sample [arduino project](/firmware/esp32c3-blink). Run `Build` command to install necessary tools and libraries.
|
|
|
|
Next run `Upload: esp32-dev-board` task to start upload over USB. `Monitor` task should give you Serial monitor, as long as you have your board connected via USB (Serial port appears right after board boots up).
|
|
|
|
## Hardware
