CoreS3 SE ESP32S3 IoT by M5Stack
CoreS3 SE is a streamlined version of the third-generation M5Stack Core series. Powered by the ESP32-S3, it features a dual-core Xtensa LX7 processor running at 240MHz with built-in Wi-Fi and Bluetooth connectivity. It comes with 16MB of onboard flash memory and 8MB of PSRAM.
Compared to the standard CoreS3, the SE version removes the camera, proximity sensor, IMU (BMI270), and magnetometer (BMM150) for a lower price point while retaining the core functionality.
CoreS3 SE features a 2.0-inch capacitive touch IPS screen protected by high-strength glass. Power management is handled by the AXP2101 chip with a 4-way power flow control loop for efficient, low-power operation. The device includes a BM8563 RTC chip for accurate timing and sleep-timer wake-up functions.
Sound output uses the high-fidelity 16-bit I2S AW88298 power amplifier chip with a built-in 1W speaker. For audio input, the kit incorporates the ES7210 audio decoding chip with dual microphones.
Note: This build includes support for the M5GO Battery Bottom 3 accessory. The SD card is not yet functional in this build.

Absolute Newest
Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
Previous Versions of CircuitPython
All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.
Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
