Overview
The M5Stack AtomS3R is a highly integrated IoT programmable controller built around the ESP32-S3-PICO-1-N8R8 System-in-Package, delivering dual-core Xtensa LX7 processing at 240MHz with 8MB flash and 8MB PSRAM in a remarkably compact 24x24mm form factor weighing just 6.8g.
Building on the AtomS3, the AtomS3R adds a BMI270 6-axis IMU and BMM150 3-axis magnetometer for full 9-DoF motion and orientation sensing, an LP5562 4-channel LED driver for precise RGB control, and an enhanced 3D PCB antenna for improved wireless performance. The 0.85-inch IPS LCD (128x128) driven by GC9107, IR transmitter, and Grove port round out a feature set that supports robotics, motion tracking, voice assistant (with Echo Base), and IoT control applications.
