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.

Microcontroller

ESP32S2

Frequency

240MHz

Flash

4MB

RAM

320KB

Vendor

Franzininho

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

Debugging

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

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

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.
