Architecture Xtensa

In Arduino IDE 2, open Boards Manager, search "esp32" by Espressif and install it. Then go to Tools → Board and select "M5stack Station" for the M5Stack-Station.

platformio.ini


[env:m5stack-station]
platform  = espressif32
board     = esp32dev
framework = arduino

; Exact hardware config for M5Stack-Station
board_build.mcu        = esp32
board_build.f_cpu      = 240000000L
board_build.flash_size = 16MB
board_build.flash_mode = dio
board_upload.flash_size = 16MB

The board value is a close generic match - check PlatformIO board registry for an exact fit.
