Franzininho WiFi Board¶

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.

Configuration¶

Please use esp32-s2-franzininho ID for board option in “platformio.ini” (Project Configuration File):

[env:esp32-s2-franzininho]
platform = espressif32
board = esp32-s2-franzininho

You can override default Franzininho WiFi Board settings per build environment using board_*** option, where *** is a JSON object path from board manifest esp32-s2-franzininho.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:esp32-s2-franzininho]
platform = espressif32
board = esp32-s2-franzininho

; change microcontroller
board_build.mcu = esp32s2

; change MCU frequency
board_build.f_cpu = 240000000L

Uploading¶

Franzininho WiFi Board supports the following uploading protocols:

• cmsis-dap

• esp-bridge

• esp-prog

• espota

• esptool

• iot-bus-jtag

• jlink

• minimodule

• olimex-arm-usb-ocd

• olimex-arm-usb-ocd-h

• olimex-arm-usb-tiny-h

• olimex-jtag-tiny

• tumpa

Default protocol is esptool

You can change upload protocol using upload_protocol option:

[env:esp32-s2-franzininho]
platform = espressif32
board = esp32-s2-franzininho

upload_protocol = esptool

Debugging¶

Debugging - “1-click” solution for debugging with a zero configuration.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Franzininho WiFi Board does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.
