Arduino-CLI is a powerful command-line tool for compiling and uploading Arduino sketches to various microcontrollers. This tutorial focuses on its use with the ESP32 family of boards, with special attention to the newer ESP32-C6. The instructions are applicable to all ESP32 variants supported by Arduino, including:
- ESP32
- ESP32-S2
- ESP32-S3
- ESP32-C3
- ESP32-C6
- ESP32-H2
Whether you're working with the versatile ESP32, the Bluetooth 5 (LE) capable ESP32-C3, or the latest ESP32-C6 with Wi-Fi 6, this guide has you covered.
- Arduino and CLI basics
- Windows, macOS, or Linux computer
- ESP32-C6 board
- USB cable
- Download Arduino-CLI.
- Add to system PATH.
- Verify:
arduino-cli version
- Update index:
arduino-cli core update-index
- Install ESP32 core:
arduino-cli core install esp32:esp32
- Verify:
arduino-cli core list
arduino-cli sketch new MyESP32C6Project
cd MyESP32C6Projectarduino-cli compile --fqbn esp32:esp32:esp32c6 ./- List boards:
arduino-cli board list
- Note your board's port (e.g., /dev/ttyACM0 or COMx).
- Upload:
arduino-cli upload -p /dev/ttyACM0 --fqbn esp32:esp32:esp32c6 ./
- "Board not found": Verify core installation and FQBN.
- Upload issues: Check USB connection and port.
