Atom Lite, which has a size of only 24*24mm
, is a very compact development board in the M5Stack development kit series. It provides more GPIOs 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
technologies and has a 4MB
of integrated SPI flash memory. Atom Lite board provides an Infra-Red LED, a RGB LED, buttons, and a HY2.0 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.

Connect the device to the PC, open the device manager to install
FTDI driver
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).
