AtomS3-Lite

SKU:C124

Description

AtomS3-Lite is a programmable controller from the Atom series in the M5Stack development kit series, using ESP32-S3 as the main controller. Its size is only 24.0 x 24.0 x 9.5mm. The main controller uses the ESP32-S3FN8 solution, with 8 MB of SPI flash, integrated Wi-Fi functionality, built-in 3D antenna, 5V to 3.3V power circuit, providing infrared emitter, RGB status indicator, button, and GROVE/HY2.0 - 4P interface. The bottom of the product has power and 6 GPIO pin headers for easy expansion applications. The onboard USB Type-C interface allows for program downloading and serial communication, with an M2 screw hole on the back for fixing. Suitable for various embedded smart device applications.
