For Core2 AWS Deep Sleep Wake:
The M5Stack Core2 AWS exposes ESP32 RTC GPIOs GPIO36 (VP), GPIO39 (VN), GPIO34, GPIO35, GPIO25, GPIO26, GPIO27, and GPIO32 for external wakeup triggers. Configure via esp_sleep_enable_ext0_wakeup() or esp_sleep_enable_ext1_wakeup(). Check the Core2 pinout to avoid conflicts with built-in peripherals.
Note: Some pins may require pull-up/down resistors. Test with low-power triggers (e.g., buttons) to verify wakeup reliability.
