### Cables & Accessories

| Item                                     | Purpose                           |
| ---------------------------------------- | --------------------------------- |
| Developer Micro USB **or** USB-C cable   | SSH / serial connection to DCS2   |
| Power supply (see expansion board specs) | Powering the system via VDD\_MAIN |
| HDMI cable *(optional)*                  | Direct display output             |
| Keyboard + monitor *(optional)*          | Local access without SSH          |

### Power Supply

The required voltage depends on your specific extension board. Before connecting power:

1. Identify your extension board model.
2. Visit the [Expansion Boards](/autopilots/dronecore-2/boards/expansion-boards.md) documentation page.
3. Locate the **VDD\_MAIN** connector specification for your board.
4. Use a power supply within the supported voltage range.

Power is supplied by connecting directly to the **VDD\_MAIN** connector - either via the XT-type connector or by soldering power lines directly to the board.
