ESP32 details

I like this device It’s very powerful and low cost with an effective value WIFI microcontroller.

You can find It here ESP32 Dev Kit v1 - Selectable - TTGO T-Display 1.14 ESP32 - NodeMCU V3 V2 ESP8266 Lolin32 - NodeMCU ESP-32S - WeMos Lolin32 CP2104 CH340 - ESP32-CAM programmer - ESP32-CAM bundle - ESP32-WROOM-32 - ESP32-S

Specs

Remember that exist a lot of variant of this device, some have a specified killer function, so this is a generic specs description.

This device is very powerfull, you can see that there are a capacitive touch pins, more than one UART various Analog pin.

How to

You must download drivers for USB chip, probably you have an esp32 version with cp2102, but exist variant with ch340 chip.

Than you must configure your Arduino IDE

Add the boards to Arduino IDE

First you must add esp32 url descriptor to your IDE
https://dl.espressif.com/dl/package_esp32_index.json
Go to File –> Preferences and add the url on “Additional Boards Manager URLs”

Arduino IDE esp32 additional board manager
Arduino IDE esp32 additional board manager

Than you must add new board in Boards Manager

Select board manager

The boards to select is esp32

Arduino IDE esp32 boards manager
Arduino IDE esp32 boards manager

Select correct board

Now you can select (if you have like me that model) the ESP32 Dev Module

Arduino IDE esp32 select board on menu
Arduino IDE esp32 select board on menu

Now you can upload your sketch.
