Overview
The M5Stack CoreS3 Lite is a compact, feature-rich IoT development controller built around the ESP32-S3FN16R8 dual-core processor with 16MB flash and 8MB PSRAM. It packs a 2.0-inch capacitive touch IPS display (320x240), a 0.3MP GC0308 camera, proximity/ambient light sensor, 6-axis IMU, 3-axis magnetometer, dual MEMS microphones, and a 1W speaker into a 54x54mm form factor.
The audio subsystem features a full-duplex solution with an AW88298 I2S amplifier and ES7210 quad-channel audio ADC, making it ideal for voice assistant applications. Power management is handled by the AXP2101 PMIC with a built-in 200mAh LiPo battery. Expansion is available through Grove-compatible ports and a 30-pin M-Bus header for stackable modules.
