# ATOM Library
English | [中文](README_cn.md)
## Description
**ATOM U** is a compact low-power consumption speech recognition IoT development kit. 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).
- LOW-CODE DEVELOPMENT:
- ATOM U supports UIFlow graphical programming platform, scripting-free, cloud push;
Fully compatible with Arduino, MicroPython, ESP32-IDF, and other mainstream development platforms, to quickly build various applications.
- HIGH INTEGRATION:
- ATOM U contains a USB-A port for programming/power supply, IR emitter, programmable RGB LED x1, button x1;
Finely tuned RF circuit, providing stable and reliable wireless communication.
- STRONG EXPANDABILITY:
- ATOM U is easy access to M5Stack's hardware and software system

- Development platform:
- [UIFlow](http://flow.m5stack.com)
- [MicroPython](http://micropython.org/)
- [Arduino](http://www.arduino.cc)
## Application
- IoT controller
- Voice recording, Speech-to-Text services
## Driver Installation
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).
