Electronic, 3D printing and embedded programming
ESP32-WROOM-32 is a powerful, generic Wi-Fi+BT+BLE MCU module that targets a wide variety of
applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding,
music streaming and MP3 decoding.
At the core of this module is the ESP32-D0WDQ6 chip*. The chip embedded is designed to be scalable and
adaptive. There are two CPU cores that can be individually controlled, and the CPU clock frequency is adjustable
from 80 MHz to 240 MHz. The chip also has a low-power co-processor that can be used instead of the CPU to
save power while performing tasks that do not require much computing power, such as monitoring of
peripherals. ESP32 integrates a rich set of peripherals, ranging from capacitive touch sensors, Hall sensors, SD
card interface, Ethernet, high-speed SPI, UART, I²S and I²C.
Even though Raspberry Pi Foundation has released the Pico W version, I still find this tutorial useful for adding WiFi to rp2040 boards using an ESP32.
We will use an esp32-wroom-32 (or esp32-s) as WiFi coprocessor and the full potential WiFiNINA library to handle it.
We have already looked at how to add a wiring connection to an STM32, but sometimes the only solution can be a Wireless or WiFi connection, and in this article we are going to see how to manage a complete WiFi solution.
I’m going to use the esp32, and the first problem was how to put It on breadboard, so we are going to print an adapter, then I build a PCB to program.
ESP32, continue the little guide on how to use this low cost but powerful microcontroller with WIFI integrated.
