2️⃣ Quick Start

PlatformIO

1. Install VisualStudioCode and Python
2. Search for the PlatformIO plugin in the VisualStudioCode extension and install it.
3. After the installation is complete, you need to restart VisualStudioCode
4. After restarting VisualStudioCode, select File in the upper left corner of VisualStudioCode -> Open Folder -> select the LilyGo-Cam-ESP32S3 directory
5. Click on the platformio.ini file, and in the platformio column, cancel the sample line that needs to be used, please make sure that only one line is valid
6. Click the (✔) symbol in the lower left corner to compile
7. Connect the board to the computer USB
8. Click (→) to upload firmware
9. Click (plug symbol) to monitor serial output
10. To use the AllFunction and MinimalSoundDetectionExample examples, additional model files need to be uploaded, follow the steps below
    • Click PlatformIO (the little bee icon) on the left side of VisualStudioCode
    • select t-cameras3
    • Select Platform
    • After making sure the board is connected to USB, click Upload Filesystem image

ArduinoIDE

1. Install Arduino IDE
2. Install Arduino ESP32, ESP32 core version should be lower than V 3.0.0, 2.0.17 is recommended
3. Copy all the folders in the LilyGo-Cam-ESP32S3/lib directory to <C:\Users\%USERNAME%\Documents\Arduino\libraries>. If there is no libraries directory, please create a new one. Please note that you are not copying the lib directory, but copying the folders in the lib directory
4. Open ArduinoIDE -> Tools
   • Board -> ESP32S3 Dev Module
   • USB CDC On Boot -> Enable ## Note that you need to change Enable to Disable when USB is not connected, so USB CDC will not prevent the board from starting
   • CPU Frequency -> 240MHz
   • USB DFU On Boot -> Disable
   • Flash Mode -> QIO 80MHz
   • Flash Size -> 16MB(128Mb)
   • USB Firmware MSC On Boot -> Disable
   • PSRAM -> OPI PSRAM
   • Partition Scheme -> 16M Flash(3MB APP/9.9MB FATFS)
   • USB Mode -> Hardware CDC and JIAG
   • Upload Mode -> UART0/Hardware CDC
   • Upload Speed -> 921600
5. Insert USB into the PC and click Upload <If the upload fails, View the Tips below>

3️⃣ Tips:

1. Can I use the Arduino IDE?
   • AllFunction and MinimalSoundDetectionExample 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
2. 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
3. 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
4. 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 , 5V is the silkscreen name of the board. The actual output is equal to the input voltage. The VSYS output is equal to the input voltage.
5. 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.
6. All onboard peripherals except OLED can be powered off
7. 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
8. 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.
9. ⚠ 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
10. 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
11. The board uses USB as the JTAG upload port. When printing serial port information on USB_CDC_ON_BOOT configuration needs to be turned on. If the port cannot be found when uploading the program or the USB has been used for other functions, the port does not appear. Please enter the upload mode manually.
    1. Connect the board via the USB cable
    2. Press and hold the BOOT button , While still pressing the BOOT button, press RST
    3. Release the RST
    4. Release the BOOT button
    5. Upload sketch
