## Description
`CoreS3` is the third generation of the M5Stack development kit series, its core master adopts the `ESP32-S3` solution, `dual-core Xtensa LX7` processor, the main frequency is`240MHz`, comes with '`WiFi`function, and the onboard `16MFLASH`and `8M-PSRAM`; It can `download the program`through the `TYPE-C` interface, support `OTG and CDC`functions, and facilitate external USB devices and flashing firmware; The front is equipped with a `2.0-inch capacitive touch IPS screen`, and the panel is made of `high-strength glass material`; A `30w pixel camera GC0308` is built into the bottom of the screen, with `proximity sensor LTR-553ALS-WA`; The power supply part adopts `AXP2101 power management core`chip and `4-way power flow control loop`, and the overall adopts `low power consumption` design; On-board `6-axis attitude sensor BMI270 and magnetometer BMM150`; On-board `TF-card (microSD)` card slot; On-board BM8563 `RTC` chip, providing accurate timing and `sleep-timer wake-up` function; In terms of sound output, it adopts high-fidelity `16bits-I2S` power amplifier chip AW88298, and the fuselage has a built-in `1w speaker`; In terms of sound input, ES7210 `audio decoding chip + dual microphone input` is adopted; On the side of the fuselage, there is a `independent power button and restart (RST) button`, self-built delay circuit, `long press the reset button to enter the program download mode`. The CoreS3 set comes with a `DinBase Base` by default, which is convenient for `Din rail, wall and screw fixing`; It can be powered by external `DC 12V (support 9~24V)` or internal `500mAh lithium battery`; DinBase reserves multiple `proto` locations for users to `DIY`. This finished product is suitable for scenarios such as `Internet of Things development, various DIY project development, smart home control system and industrial automation control system`.
**Power on and off operation:**
Power on: Click the left power button
shut down: Long press the left power button for 6 seconds
reset: Click the bottom RST button

## PlatformIO Compilation
[Compilation File](https://github.com/m5stack/M5CoreS3/blob/main/platformio.ini)
## Start with Board Support Package
To speed up prototyping on some development boards, you can use [Board Support Packages](https://github.com/espressif/esp-bsp) (BSPs), which makes initialization of a particular board as easy as few function calls.
A BSP typically supports all of the hardware components provided on development board. Apart from the pinout definition and initialization functions, a BSP ships with drivers for the external components such as sensors, displays, audio codecs etc.
The BSPs are distributed via IDF Component Manager, so they can be found in IDF Component Registry.
Here is an example of how to add M5CoreS3 BSP to your project:
`idf.py add-dependency m5stack_core_s3`
More examples of BSP usage can be found in [BSP examples folder](https://github.com/espressif/esp-bsp/tree/master/examples).
