ESP32 Guide 2024 – Choosing and Using an ESP32

ESP32 Guide 2024 – Choosing and Using an ESP32

Since its introduction in 2016, the ESP32 has become one of the most popular microcontrollers in the world. It has now grown from a single ESP8266 replacement chip into a complete line of powerful microcontrollers and communications modules.

Today we will look at the status of the ESP32 as of January 2024. We will also take a look at a new Alpha of the ESP Boards Manager for the Arduino IDE.

LoRa – Getting Started with Arduino, ESP32 & Pico

LoRa – Getting Started with Arduino, ESP32 & Pico

LoRa is a Long Range radio system that is inexpensive and free to use. You can achieve great distances with a simple wire antenna, and LoRa is very easy to use.

Today we will see how LoRa works and how we can use LoRa modules to communicate between Arduino, ESP32 and Raspberry Pi Pico boards.

We’ll also build a data-gathering system that you can easily expand upon.

Arduino Uno R4 – Minima & WiFi

Arduino Uno R4 – Minima & WiFi

After 12 years, Arduino has released the latest edition of the classic Arduino Uno. Actually, it’s two boards, the Arduino Uno R4 Minima and the Arduino Uno R4 WiFi.

These boards are 5-volt logic devices and are physically compatible with the older Arduino Uno R3 boards, preserving your investment in shields and prototyping equipment. In addition, they offer many new features, several of which we’ll examine today.
