Heltec WiFi Kit 32¶

Hardware¶

Platform Espressif 32: Espressif Systems is a privately held fabless semiconductor company. They provide wireless communications and Wi-Fi chips which are widely used in mobile devices and the Internet of Things applications.

Configuration¶

Please use heltec_wifi_kit_32 ID for board option in “platformio.ini” (Project Configuration File):

[env:heltec_wifi_kit_32]
platform = espressif32
board = heltec_wifi_kit_32

You can override default Heltec WiFi Kit 32 settings per build environment using board_*** option, where *** is a JSON object path from board manifest heltec_wifi_kit_32.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:heltec_wifi_kit_32]
platform = espressif32
board = heltec_wifi_kit_32

; change microcontroller
board_build.mcu = esp32

; change MCU frequency
board_build.f_cpu = 240000000L

Uploading¶

Heltec WiFi Kit 32 supports the following uploading protocols:

• espota

• esptool

Default protocol is esptool

You can change upload protocol using upload_protocol option:

[env:heltec_wifi_kit_32]
platform = espressif32
board = heltec_wifi_kit_32

upload_protocol = esptool
