🛠 Advanced power management and deep sleep on ESP32-S3
Hardware: PaperDIY Assembly Kit, multimeter, USB-C cable. 1. Analyze the Assembly Kit schematic to identify power lines causing leaks (especially e-paper and WiFi module). 2. Configure GPIOs as low-output before sleep to cut power to non-essential peripherals. 3. Use ESP32-S3 power management APIs to disable WiFi and Bluetooth before entering deep sleep. 4. Configure a timer or GPIO interrupt wake-up (via touch button or external sensor). 5. Optimize the duty cycle: wake, read sensor, update screen, re-enter sleep. 6. Measure sleep current with a multimeter in microamp mode. Verification: Sleep current must be below 10µA. Deep dive: Implement dynamic sleep logic based on user activity detected by ambient sensors.
