To power the M5STACK STAMPS3 Development Board, you can use the USB-C port provided on the board. The board supports an operating voltage range of 2.7V to 5.5V. When connecting external USB, pin 13 provides a voltage of 5V which can supply power to the development board or other devices.
The ESP32-S3 chip on the board supports different power modes for efficient power management:
1. **Active mode:** In this mode, the CPU and chip radio are powered on, allowing the chip to receive, transmit, or listen.
2. **Modemsleep mode:** The CPU is operational with reduced clock speed. The wireless baseband and radio are disabled, but wireless connection can remain active.
3. **Lightsleep mode:** The CPU is paused, and the RTC peripherals, as well as the ULP coprocessor, can be woken up periodically by the timer. Users can choose to shut down/keep on peripherals for power-saving purposes.
4. **Deepsleep mode:** In this mode, the CPU and most peripherals are powered down, with only the RTC memory powered on. The ULP coprocessor remains functional, and Wi-Fi connection data are stored in the RTC memory.
Each power mode serves a specific purpose in balancing functionality and power consumption based on the requirements of your application.
