The M5CoreS3 SE is a lighter version of the third-generation CoreS3 unit from the M5Stack development kit series. Powered by the ESP32-S3 with a dual-core Xtensa LX7 processor running at 240MHz, it includes 16MB FLASH and 8MB PSRAM, supporting program downloads via a USB Type-C connector which supports OTG and CDC functions, making it convenient to connect USB devices and burn firmware. It features a 2.0" capacitive touch IPS screen, a low-power AXP2101 power management and a 4-way power flow control circuit for low power consumption. There is also a MicroSD card slot and a BM8563 RTC chip for precise timing. In regards to sound input/output, it includes a 16-bit I2S amplifier with a built-in speaker and dual microphone inputs. It has an independent power button and reset (RST) button on the side, with a built-in delay circuit. This is ideal for IoT, DIY projects, and smart home control. There is no battery base included with the SE version, but If you click here you can buy one in our store. For the CoreS3 that includes features the SE doesn't, click here (Psst, you can find out about the features of both products a bit further down this page) Note: Before downloading the program, please be sure to press and hold the reset button for 3 seconds (green light) to enter the download mode, otherwise the download will fail.
