M5Stack-ATOM

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	ESP32
Frequency	240MHz
Flash	4MB
RAM	320KB
Vendor	M5Stack

Configuration

Please use m5stack-atom ID for board option in “platformio.ini” (Project Configuration File):

[env:m5stack-atom]
platform = espressif32
board = m5stack-atom

You can override default M5Stack-ATOM settings per build environment using board_*** option, where *** is a JSON object path from board manifest m5stack-atom.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:m5stack-atom]
platform = espressif32
board = m5stack-atom

; change microcontroller
board_build.mcu = esp32

; change MCU frequency
board_build.f_cpu = 240000000L

Uploading

M5Stack-ATOM supports the following uploading protocols:

• espota

• esptool

Default protocol is esptool

You can change upload protocol using upload_protocol option:

[env:m5stack-atom]
platform = espressif32
board = m5stack-atom

upload_protocol = esptool

Debugging

Debugging currently does not support M5Stack-ATOM board.
