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).\n\n- LOW-CODE DEVELOPMENT: \n   - ATOM U supports UIFlow graphical programming platform, scripting-free, cloud push;\nFully compatible with Arduino, MicroPython, ESP32-IDF, and other mainstream development platforms, to quickly build various applications.\n\n- HIGH INTEGRATION:\n   - ATOM U contains a USB-A port for programming/power supply, IR emitter, programmable RGB LED x1, button x1;\nFinely tuned RF circuit, providing stable and reliable wireless communication.\n\n- STRONG EXPANDABILITY:\n   - ATOM U is easy access to M5Stack's hardware and software system\n\n## Product Features\n\n- ESP32-PICO-D4 (2.4GHz Wi-Fi and Bluetooth dual mode)\n- Integrated programmable RGB LED and button\n- Compact design\n- Built-in IR emitter\n- Expandable pinout and GROVE port\n- Development platform:\n   - [UIFlow](http://flow.m5stack.com)\n   - [MicroPython](http://micropython.org/)\n   - [Arduino](http://www.arduino.cc)\n\n## Application\n\n- IoT controller\n- Voice recording, Speech-to-Text services\n\n## Driver Installation\n\nConnect 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).
