5Description
The board sits between the antenna's tuner and its motors. It reads the signal level coming from the tuner and uses it to decide how the antenna should move, then commands the motors accordingly.
It was designed from the start to control any type of motor driver rather than one specific part, so the same board carries over between different mechanical builds instead of being redesigned for each.
An FPGA runs the control logic. Six layers keep its interfaces clean while routing power and control across more than six hundred placed components, in a stack-up that stays manufacturable at volume.
