Espressif ESP32-C3-DevKitM-1

Hardware

Platform Espressif 32: ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and Bluetooth. ESP32 integrates an antenna switch, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules.

Microcontroller	ESP32C3
Frequency	160MHz
Flash	4MB
RAM	320KB
Vendor	Espressif

Configuration

Please use esp32-c3-devkitm-1 ID for board option in “platformio.ini” (Project Configuration File):

[env:esp32-c3-devkitm-1]
platform = espressif32
board = esp32-c3-devkitm-1

You can override default Espressif ESP32-C3-DevKitM-1 settings per build environment using board_*** option, where *** is a JSON object path from board manifest esp32-c3-devkitm-1.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:esp32-c3-devkitm-1]
platform = espressif32
board = esp32-c3-devkitm-1

; change microcontroller
board_build.mcu = esp32c3

; change MCU frequency
board_build.f_cpu = 160000000L
