## 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.**

{% hint style="info" %}
**Notes:**

* This board acts as a pass-through for the power supplies from the Pilot board.
* The solder bridge on current limited 5V\\\_PERIPH line to CAM2/3 connector is unsoldered by default. The default supply voltage to this connector is 3V3.
