## Description
**ATOM Matrix** and **ATOM Lite** are ESP32 development board with a size of only 24 * 24mm.It provides more GPIO for user customization which is very suitable for embedded smart home devices and in making smart toys. The main control adopts the ESP32-PICO chip which comes integrated with Wi-Fi and Bluetooth technologies and has a 4MB of integrated SPI flash memory. ATOM board provides an Infra-Red LED, RGB LED, buttons, and a PH2.0 interface. In addition, it can connect to external sensors and actuators through 6 GPIOs. The on-board Type-C USB interface enables rapid program upload and execution. ATOM Matrix have 5 * 5 RGB LED matrix, built-in IMU sensor (MPU6886).
## Applications
- Internet of things terminal controller
- IoT node
- Wearable peripherals
## 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).
