I like the board layout – nice and clean.

LeMaker confirmed that the camera connector is compatible with the current Banana Pi/Pro camera.

LeMaker also confirmed that the LCD connector will be compatible with existing Banana LVDS displays such as their 7″ module, but not with parallel RGB panels. The Guitar SOM is compatible with parallel LCD modules on custom base boards.

I appreciate the full size HDMI connector.

On the bottom of the board, we find the WiFi module, WiFi antenna connector, RTC battery socket, audio amp (a nice touch), and DC-DC power supply.
