Testing My ESP32-S3 Camera Baord

In order to test the USB functionality of the ESP32-S3, I bought the following camera/microphone board:

Before testing the USB I implemented and executed the following test cases for each hardware component:

• Testing the user button
• Testing the LED
• Testing the Color LED
• Testing the SD
• Testing the SDMMC
• Testing the PSRAM
• Testing the Camera
• Testing the Microphone

Here is a summary of the limitations/issues that I have found:

• I could not make the 4 pin SDMMC to work.
• The microphone just provides noise
• The board has no Boot button, so you can not set the board easily into upload mode. Here is the work around:
  • connect GND with Pin 0
  • press and release the SWT2 (Reset/EN button)
  • disconnect Pin 0

My first USB tests with TinyUSB for Video and Audio were failing, so I need to look into this in more detail.
