The preceding figure shows the composition of the MX hardware system, which mainly
comprises the following units:
 Main board:
˗ DC-DC module: DC-DC circuit for supplying power and charging/discharging the
battery
˗ PHV module: PHV circuit for providing PHV and HV power for the transmit circuit
˗ Backend functional circuit: implementing audio, video, IO interface, and other
functions
˗ FPGA module: implementing video processing, IO interface control, transmit/receive
control, and signal processing
˗ Transmit/receive channel: 64 channels
˗ HV switch module: implementing adaption between 64 channels and 128 channels
˗ Probe related control interface
˗ Power management (EC): power management and control for starting or shutting down
the main unit
˗ System monitoring (SM): power and fan monitoring for the main system
