[EOL] AtomU ESP32 Development Kit with USB-A
Description
AtomU is an ultra-compact and flexible IoT voice-recognition development board powered by Espressif’s ESP32. It is equipped with two low-power Xtensa® 32-bit LX6 microprocessors running at up to 240 MHz. The board integrates peripherals such as a USB Type-A interface, IR transmitter, and a programmable RGB LED, allowing true plug-and-play use for uploading, downloading, and debugging firmware.
With its built-in Wi-Fi module and on-board digital microphone SPM1423 (PDM), AtomU enables clear audio recording, making it ideal for human–machine interaction and speech-to-text (STT) applications in various IoT scenarios.
