PCB Design
The board is designed in EasyEDA Pro.
PCBA prototyping is done by PCB-Hero.
Power Supply
Texas Instruments TPS56A37 is used for getting regulated 5V 8A from 7 ~ 28V DC input.


HDMI
Orange Pi CM5 supports HDMI2.1 for 8k display driving. Because HDMI2.1 uses AC coupling unlike HDMI2.0, the optional DC bias circuit is required to support backward compatibility.


GPS
The high precision Multi-band GNSS receiver, UBlox ZED-F9P is used.


Wi-Fi and Bluetooth
For Wi-Fi and Bluetooth, AP6265 is used. This part of board is copied from the Orange Pi CM5 Base Board.


ADC
32 channels of ADC input is implemented using 4 x 4-ch 12-bit ADC, Texas Instruments ADS1015.
