New Unit: ESP32 Web Server Introduction

Hi there! I hope you are doing well.

I’ve just released a new Unit for the Programming ESP32 with Arduino IDE course: ESP32 Web Server Introduction.

Important Update

If you recently purchased an ESP32 DEVKIT V1 DOIT board from Banggood, you probably received a board with 36 pins (the old version had 30 pins).

You’ll probably never use the extra 5 pins (the ones marked with a *), because they are connected to the SPI chip that is integrated in the ESP32.

I’ve updated the Intro module with the new pinout (and the other Units): https://rntlab.com/introducing-esp32/

You can download and print the new pinout for ESP32 DOIT here:

During the course, when you’re wiring any of the circuits always double-check that you’re connecting the components to the right GPIO (not the pin number). Future course Units will be presented with the new 36 pins ESP32 board, but the projects are compatible with all ESP32 boards.

Next Week

Next week, I’ll be adding new Units to the course about building an ESP32 web server.

Thanks for reading,

Rui
