M5Stack PaperDIY Complete Kit · avance · Caractérisez la consommation réelle de la puce M5PM1 et de l'ESP32-S3 en mode veille profonde avec instrumentation externe.
Hardware: PaperDIY, external power supply, precision multimeter or oscilloscope with current probes. 2. Preparation: Carefully open the 3D-printed case to access power test points, or use accessible pads if available. Isolate the power line of the ESP32-S3 module. 3. Software setup: In Arduino/ESP-IDF code, configure wake-up by GPIO or RTC. Explicitly disable WiFi and Bluetooth 5.0 LE. Put the e-paper screen in standby mode before entering Deep Sleep. 4. Commands: Launch the test program. 5. Verification: Measure leakage current. The goal is to approach M5PM1 specifications. Note that the 140 mAh battery requires strict management. 6. Analysis: Plot the power consumption curve. Identify wake-up spikes. 7. Deep dive: Adjust RTC wake-up frequency and test the impact of temperature on the integrated LiPo battery consumption.
