Atom-Lite

SKU:C008

Description

Atom-Lite is a very compact development board in the M5Stack development kit series, with a size of only 24.0 x 24.0 mm, providing more GPIO for user customization, making it very suitable for embedded smart hardware development. The main controller uses the ESP32-PICO-D4 solution, integrates a Wi-Fi module, has a built-in 3D antenna, and features 4 MB of SPI flash, providing Infra-Red, RGB Led, button, and GROVE/HY2.0 interfaces. The onboard USB Type-C interface allows for quick program upload and download, and there is an M2 screw hole on the back for fixing.

USB Driver

Atom-Lite may not work without a driver on some systems. You can resolve this issue by manually installing the FTDI VCP driver.

1. Select the driver file that matches your operating system from the list below, download it, and extract it. You can also visit the FTDI Chip official website for additional FTDI driver versions.

2. Connect the device to your PC, open Device Manager, and install the FTDI driver (the screenshot below uses Windows 10 as an example). (Note: On some systems, you may need to install the driver twice for it to take effect. The unrecognized device is usually named M5Stack or USB Serial.)
