Description
AtomS3R-Ext is a programmable controller based on the ESP32-S3 main control, designed for prototype development and extension. It features a universal expansion board on top, allowing users to connect and debug multiple IO ports, suitable for expanding and verifying various peripheral modules. It integrates the ESP32-S3-PICO-1-N8R8 main control, supports Wi-Fi functionality, and includes 8 MB of on-chip Flash and 8 MB of PSRAM, along with a power circuit converting 5V to 3.3V/2.8V/1.2V. It has a built-in three-axis BMM150 geomagnetic sensor and a six-axis BMI270 attitude sensor. The controller is equipped with a USB Type-C interface for power supply and firmware download, and features a HY2.0-4P expansion port, six GPIO and power pins for easy function expansion. Compared to previous ATOM series host products, the 3D antenna of AtomS3R-Ext has been enhanced, providing better signal performance and stability. With dimensions of only 24.0 x 24.0 x 12.0mm, it is ideal for prototype development and verification applications in embedded smart devices.
