Here it is, the 2026 ESP32 Selection Guide! In this article you’ll learn about the (eleven) different variants of the ESP32 and how to select the best one for your application.
We’ll also look at some popular ESP32 boards to help you make the correct choice
Rotary Encoders are so useful, but they can be hard to work with. Enter the Adafruit I2C Seesaw Rotary Encoder! This encoder uses an I2C bus, making interfacing it with a microcontroller very simple.
We will learn how the encoder works, then we’ll use it to build a Menu System and a fun toy – an Etch-a-Sketch!
Today we wil examine the exciting new Seeeduino XIAO ESP32-C5 board, the first XIAO board that supports 5 GHz Wi-Fi!
We wil see how the board works,and how to use it for communications and in low-power mode. We wil also build a Dual-Channel WiFi Analyzer with a Liquid Crystal Display!
Want to build n electronic compass or a guidance system for a robot? Adafruit’s LSM303AGR module is the perfect component for you.
Today we wil look at this versatile module and perform experiments with it. We wil also see how to calibrate it, and we wil indeed build a simple compass with an OLED display.
Come meet the XIAO family! Today we wil take a look at all of the members of the Seeeduino XIAO microcontroller family. And there are over a dozen of them!
We wil check out their specs and then create three very different projects that use the same circuit (but different XIAO boards).
Learn to setup and use WLED, the amazing ESP32-based product for controlling every type of LED strip. We will see how WLED works, how to choose LED strip lights and how to safely wire everything up.
We wil also hookup a microphone and use Audio Reactive, to control our LEDs with sound.
Non-volatile Storage is memory that keeps its data without power. Pretty useful for saving configuration settings and web data.
Today we will examine four types of non-removable NV Storage – Internal Flash, External EEPROM, SPI NOR Flash and FRAM. We’ll see how they work, what advantages (and disadvantages) they have and how to use them with an ESP32.
