This repository hosts specially recompiled libraries for the arduino-esp32 SDK. These libraries are compiled from the esp-arduino-libs/esp32-arduino-lib-builder. In ...

Before reporting an issue, make sure you've searched for similar one that was already created. Also make sure to go through all the issues labelled as Type: For reference. We have set-up CI testing ...

If you use the Arduino IDE to program the ESP32, you might be interested in [Andreas Spiess’] latest video (see below). In it, he shows an example of using all three ESP32 UARTs from an Arduino ...

Now let’s look at the simple workflow of the Rainmaker and how it works. Once the ESP32 is programmed with ESP RainMaker firmware, the ESP32 will generate and display a QR code in the serial monitor ...

Some of the newer Espressif Systems wireless SoCs such as the ESP32-H2 and ESP32-C6 support Zigbee through their built-in 802.15.4 radio. It’s been working since the release of the ESP-IDF 5.1 ...

The ESP32 seemed to appear from nowhere. Now it is everywhere! Simplifying connectivity with Wi-Fi networks and Bluetooth devices, it has become a staple of the maker community. We take a look at its ...

Bojan Jurca’s open-source Arduino sketch "Esp32_oscilloscope," transforms any ESP32 board to function as a web-based oscilloscope accessible over WiFi. While the Scoppy project demonstrated the ...

ESP32 is a versatile microcontroller and a great starting point for anyone venturing into the IoT realm, but its configuration and interfacing of sensors can be challenging for new users. Arduino ...

We just got our hands on some engineering pre-samples of the ESP32-C3 chip and modules, and there’s a lot to like about this chip. The question is what should you compare this to; is it more an ESP32 ...

We previously noted the ESP32 Arduino Core 3.0.0 Alpha release added support for ESP32-C6 and ESP32-H2 among other changes. The good news is that Arduino ESP32 Core 3.0.0 is now considered stable, and ...
