One of features of ESP32 that has been intriguing me since its release back in September 2016 was low noise amplifier (LNA). Some time later, in May 2017, the LNA has been officially documented in ...

In the first part of this series, we presented the ESP32 Audio Transceiver Board and its associated modules, especially the ESP32-S3 DevKit and the I2S2 DAC/ADC module for playing and sampling music ...

ESP32 controllers are well-like solutions used in thousands of IoT, smart home, and other remote control projects. The ESP32 has also a good I2S interface, which can be used to output and input ...

Audiophiles have worked diligently to alert the rest of the world to products with superior sound quality, and to warn us away from expensive gimmicks that have middling features at best.

A new Arduino compatible audio development board will soon be launching via the Crowd Supply website offering an open source design for audio and digital signal processing (DSP) applications. The ...

The Waveshare ESP32-S3-Knob-Touch-LCD-1.8 is a batterry-powered knob display board designed for HMI applications that combines ESP32-S3 and ESP32 SoCs in a dual MCU architecture. The design differs ...

We featured [Fabrizio Di Vittorio]’s FabGL library for the ESP32 back in April of this year. This library allows VGA output using a simple resistor based DAC (3 resistors for 8 colors; 6 resistors for ...

Waveshare ESP32-S3-Touch-LCD-1.85C is an ESP32-S3 development kit with a 1.85-inch round touchscreen display with 360×360 resolution, support for Wi-Fi & Bluetooth BLE 5, and a built-in microphone.

Abstract: This work has the purpose of presenting the expansion of Arduino Library for PNRD (elementary Petri Net inside RFID distributed Database) and iPNRD (inverted PNRD) to ESP32 platform to reach ...
