Is this compatible with the FireBeetle 2 Board ESP32-S3-U (N16R8) AIoT as well?

Hi! What is the purpose of the terminal labeled "ARE" (in the lower right part)? It is not listed in the wiki. Also, which terminal is the SPI Chip Select (for the SPI terminals in the lower part)?

I attached the schematic diagram of FireBeetle 2 ESP32-E, and the ARE at the corresponding position is not connected to any pin.
Also, regarding the CS you asked about. In the SPI protocol, CS is just a high or low level signal. CS can be connected to any GPIO. https://uploads.disquscdn.c... https://uploads.disquscdn.c...

ESP32-E and ESP32-S3-U (N16R8) AIoT have the same size and pins, but there is no camera interface on this terminal block board.
