Description
DCS2.Adapter default is a general-purpose adapter board used to bridge and adapt connections between DroneCore components. It enables compatibility between different board layouts or connector standards within the DroneCore Suite, simplifying system integration and hardware configuration. A separate PDB board is required to make the DCS2 setup complete.

There is a possibility to switch the power supply to this connector from 3V3_AD to 5V_PERIPH by shorting the solder bridge on the bottom side of the board. The current limitation of the 5V supply line is 1A
Pay attention to the cable pins' orientation (same/opposite side contacts). Cameras from different manufacturers can have different pin orders, so a wrong cable can cause a short-circuit!
