Tips:

• Can I use the Arduino IDE? All Function and Minimal Sound Detection Example examples are not acceptable, because model files and custom partition tables need to be uploaded. Currently, Arduino IDE does not support custom partition tables and upload model files (the time to write README is 20220930)
• The rest of the examples are available using the Arduino IDE The board integrates PMU (Power management chip), which has short circuit and overload protection. By default, PWRKEY needs to be pressed for 6 seconds to turn off the power supply of the board. Press PWRKEY for 128 milliseconds to turn on the power supply. If you need to modify the shutdown pressing time, please refer to MinimalPowersExample
• The PMU TS Pin detection function needs to be turned off if the charging function is required. There is no NTC sensor on the board by default, so you need to disable the TS Pin detection function to use the charging function normally. If the TS Pin detection function is not turned off, insert the battery After the PMU charging indicator will flash, charging will be disabled at this time
• The external 5 Pin expansion socket of the board, 5V is shared with PMU SYS, please do not connect an external power supply load greater than 600mA, 3.3V use PMU DCDC3 power supply, the voltage can be adjusted, The maximum output current should not exceed 1A
• The display screen shares the DCDC1 power channel with the ESP32S3 core, so the display power supply cannot be turned off. Please set the display screen to sleep mode to reduce power consumption when sleeping.
• All onboard peripherals except OLED can be powered off
• When the sketch cannot be uploaded, please press and hold the BOOT button on the board, then insert the USB, you should be able to see the port in the device manager of the computer, and then click upload sketch again
• When the power supply channel of ESP32S3 is closed by mistake, please insert the USB, then press and hold the BOOT button of the board, then press and hold the PWRKEY button, the board enters the download mode, and the sketch can be uploaded normally.
• Please understand the risks you need to face before changing the peripheral voltage, otherwise please do not try to change the voltage of the camera and other onboard devices, you may face permanent damage
• When you think there is a problem with the board, you can try to burn our factory firmware for testing. You can first rule out whether it is a hardware problem FactoryFirmware
