Quick Setup

Copy-paste configs for RoboHeart Hercules - auto‑generated from this board’s exact hardware specs.

ESP32 240 MHz 4MB DIO Xtensa

In Arduino IDE 2 select Roboheart Hercules from the esp32 by Espressif package. In PlatformIO use board = esp32dev. ESP32 · 240 MHz · 4MB · DIO.

Arduino IDE PlatformIO ESPHome esptool

Tools menu settings Copy

Board (select in Arduino IDE) Roboheart Hercules

CPU Frequency 240 MHz

Flash Size 4MB

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 “Roboheart Hercules” for the RoboHeart Hercules.

platformio.ini Copy

[env:roboheart_hercules]
platform  = espressif32

; Exact hardware config for RoboHeart Hercules
board_build.mcu        = esp32
board_build.f_cpu      = 240000000L
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.
