The top gimbal board is responsible for video processing and encoding for SD-card output. Downscaled video stream is provided at a connector, to allow FPV. The board also controls the gimbal, and contains yaw motor driver. Drivers for two remaining gimbal motors are placed on separate boards. The board allows firmware update via SD-card slot, but only Ambarella firmware is updated that way.
There are multiple versions of the board.
