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. ## Where to Buy - [M5Stack Official](https://openhardware.directory/r?to=https%3A%2F%2Fshop.m5stack.com%2Fproducts%2Fm5stack-cores3-lite-esp32s3-iot-dev-kit&ref=openhardware.directory&product=m5stack-cores3-lite&source=md-export) — $44.90 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fshop.m5stack.com%2Fproducts%2Fm5stack-cores3-lite-esp32s3-iot-dev-kit&ref=openhardware.directory&product=m5stack-cores3-lite&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2Fm5stack%2FM5CoreS3&ref=openhardware.directory&product=m5stack-cores3-lite&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Fdocs.m5stack.com%2Fen%2Fcore%2FCoreS3-Lite&ref=openhardware.directory&product=m5stack-cores3-lite&source=md-export) ## Tags `esp32-s3`, `m5stack`, `camera`, `touch`, `imu`, `voice-assistant`, `grove` ## Images ![M5Stack CoreS3 Lite](https://nbg1.your-objectstorage.com/openhardware-directory/entities/m5stack-cores3-lite/5db937f0c142.webp) ![M5Stack CoreS3 Lite](https://nbg1.your-objectstorage.com/openhardware-directory/entities/m5stack-cores3-lite/8130f246e211.webp) > **Battery Powered:** LiPo 3.7V --- [View full device page](https://openhardware.directory/devices/m5stack-cores3-lite)
