AtomS3
SKU:C123
Description
AtomS3 is a highly integrated programmable controller based on the ESP32-S3 main controller. It integrates the ESP32-S3 main controller, Wi-Fi functionality, 8 MB on-chip FLASH, and a 0.85-inch IPS screen. Below the screen, there is a programmable button function, a built-in 5V to 3.3V circuit, and a 6-axis gyroscope sensor MPU6886. It has an onboard USB Type-C interface for power supply and firmware download, as well as a HY2.0-4P expansion port. The bottom reserves 6 GPIO and power pins for easy expansion applications. The product size is 24.0 x 24.0 x 13.0mm, suitable for various embedded smart device applications.
