The ESP32 would then take care of other low-level I/Os. However, a quick look at the schematics reveals that the ESP32 is used for USB UART, and both the ESP32 and ESP32-S3 have signals connected to ...

This week, discover the world of audio processing with this in-depth Elektor Webinar hosted by Brian Tristan Williams and our Editor-in-Chief Jens Nickel, together with Clemens Valens, the innovative ...

The popular ESP32 controllers are affordable, fast and easy to program, for example with the Arduino IDE. Equipped with Wi-Fi, they are used in thousands of IoT, Smart Home and other remote control ...

CP2102: This IC converts USB signals to serial UART signals, allowing communication with the ESP32. ESP32: The target microcontroller to be programmed. Resistors: These components set the voltage ...

The PICO DSP open-source, Arduino-compatible, ESP32-based audio dev board is now available to purchase from Crowd Supply for $29 with world ...

Overview We've made a Walkie-Talkie using the ESP32. Explanatory video Audio data is transmitted over either UDP broadcast or ESP-NOW. So the Walkie-Talkie will even work without a WiFi network!

It also has all of the I/O you would expect something based on an ESP32 to have, such as I2S stereo DAC, an I2S microphone input, I2C GPIO extenders and, of course, a built-in MicroSD card reader.
