Compact ESP32-S3 IoT Development Kit with 0.85-Inch IPS Display, 9-Axis Motion Sensing and 8 MB PSRAM

The M5Stack ATOMS3R Development Kit is a compact IoT programmable controller based on the ESP32-S3-PICO-1-N8R8 SoC. It combines 8 MB Flash and 8 MB PSRAM with integrated Wi-Fi connectivity, providing memory and processing resources for embedded control, sensing, and connected-device applications. A 0.85-inch colour IPS display with a programmable button underneath provides a convenient interface for status information, menus and direct user interaction.

For motion and orientation sensing, the ATOMS3R integrates a BMI270 6-axis IMU and BMM150 3-axis geomagnetic sensor, creating a 9-axis sensing system suitable for attitude detection and movement tracking. It also supports infrared transmission control and incorporates an enhanced 3D antenna for improved wireless stability. USB Type-C supports power input and firmware downloading, while the HY2.0-4P interface and 6 GPIO plus power pins provide flexible expansion. Measuring only 24.0 x 24.0 x 12.9 mm, ATOMS3R is well-suited for compact smart devices, IoT nodes and motion-aware embedded systems.
