It adopts an ESP32 chipset, equipped with 2 low-power Xtensa 32-bit LX6 microprocessors with the main frequency of up to 240MHz. Built-in USB-A interface, IR emitter, programmable RGB LED. Plug-and-play, easy to upload and download programs. Integrated `Wi-Fi` and `Bluetooth` modes and digital microphone SPM1423(I2S) for the clear sound record. suitable for HMI, Speech-to-Text (STT). 10 | 11 | - LOW-CODE DEVELOPMENT: 12 | - ATOM U supports UIFlow graphical programming platform, scripting-free, cloud push; 13 | Fully compatible with Arduino, MicroPython, ESP32-IDF, and other mainstream development platforms, to quickly build various applications. 14 | 15 | - HIGH INTEGRATION: 16 | - ATOM U contains a USB-A port for programming/power supply, IR emitter, programmable RGB LED x1, button x1; 17 | Finely tuned RF circuit, providing stable and reliable wireless communication. 18 | 19 | - STRONG EXPANDABILITY: 20 | - ATOM U is easy access to M5Stack's hardware and software system 21 | 22 | ## Product Features 23 | 24 | - ESP32-PICO-D4 (2.4GHz Wi-Fi and Bluetooth dual mode) 25 | - Integrated programmable RGB LED and button 26 | - Compact design 27 | - Built-in IR emitter 28 | - Expandable pinout and GROVE port 29 | - Development platform: 30 | - [UIFlow](http://flow.m5stack.com) 31 | - [MicroPython](http://micropython.org/) 32 | - [Arduino](http://www.arduino.cc) 33 | 34 | ## Application 35 | 36 | - IoT controller 37 | - Voice recording, Speech-to-Text services 38 | 39 | ## Driver Installation 40 | 41 | Connect the device to the PC, open the device manager to install [FTDI driver](https://ftdichip.com/drivers/vcp-drivers/) for the device. Take the win10 environment as an example, download the driver file that matches the operating system, unzip it, and install it through the device manager. (Note: In some system environments, the driver needs to be installed twice for the driver to take effect. The unrecognized device name is usually `M5Stack` or `USB Serial`. Windows recommends using the driver file to install directly in the device manager (custom Update), the executable file installation method may not work properly).
