Quick Setup

Copy-paste configs for BPI-BIT - auto‑generated from this board's exact hardware specs.

ESP32 160 MHz 4MB DIO Xtensa

In Arduino IDE 2 select Bpi Bit from the esp32 by Espressif package. In PlatformIO use board = esp32dev. ESP32 · 160 MHz · 4MB · DIO.

Flash Mode DIO

Upload Speed 921600

Architecture Xtensa

In Arduino IDE 2, open Boards Manager, search "esp32" by Espressif and install it. Then go to Tools → Board and select "Bpi Bit" for the BPI-BIT.

platformio.ini


[env:bpi-bit]
platform  = espressif32
board     = esp32dev
framework = arduino

; Exact hardware config for BPI-BIT
board_build.mcu        = esp32
board_build.f_cpu      = 160000000L
board_build.flash_size = 4MB
board_build.flash_mode = dio
board_upload.flash_size = 4MB

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