Electronic, 3D printing and embedded programming
The ESP32-S is a wireless module based on ESP32, supports WiFi and Bluetooth 4.2, with built-in 32Mbit Flash, in the SMD38 package. There’re also onboard PCB antenna and metal shield. In short, it’s a small form factor and fairly high cost effective wireless module.
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.
