The M5Stack ATOMS3 is a highly integrated programmable controller based on the ESP32-S3 main control, which includes the ESP32-S3 main control, integrated WiFi function, and an 8M on-chip FLASH. The AtomS3 features a 0.85" IPS display, a programmable button function at the bottom of the screen, a built-in 5V to 3.3V circuit, a 6-axis gyro sensor MPU6886, an on-board Type-C interface, a power supply port, one HY2.0 4-pin expansion port, 6 GPIOs and power pins reserved at the bottom to enable expansion applications. It measures 24 x 24mm, which is suitable for various embedded smart device applications. Note: If you need to burn the firmware, please press and hold the reset button (about 2 seconds) until the internal green LED lights up, and then you can release it. At this time the device has entered download mode.
