## Summary

M5Stack Capsule v1.1 is a compact battery-powered IoT controller built around the Stamp-S3A module (ESP32-S3FN8). It features a 6-axis BMI270 IMU, SPM1423 MEMS microphone, IR transmitter, BM8563 RTC, buzzer, microSD slot, Grove connector, and a 250 mAh battery in a 40x24x16mm form factor. The upgrade from the original Capsule brings an optimized antenna design and lower power consumption (35µA sleep, 144mA operating). It supports UIFlow2, Arduino IDE, ESP-IDF, and PlatformIO. Priced at $19.95, it targets motion tracking, audio recording, low-power timed data collection, and IR remote control applications.
