# Hardware Setup

{% hint style="info" %}
DroneCore Suite 2 is shipped with the compute module and extension board **pre-assembled**. No mechanical assembly is required before first use. If you need to replace or upgrade these components, refer to the

\[mechanical assembly guide]\(\[TODO: link]).
{% endhint %}

### 1. Verify VDD\_MAIN

Before connecting power, double-check:

* The correct power supply voltage for your extension board (see [Expansion Boards](/autopilots/dronecore-2/boards/expansion-boards.md)).
* The power connector is firmly attached to the VDD\_MAIN connector.
* No short circuits or exposed conductors are present.

### 2. Connect USB for SSH Access

Connect a **Micro USB or USB-C cable** from your host PC to the developer USB port on DCS2. This creates a USB-to-Ethernet connection used for SSH access.

### 3. Connect HDMI *(optional)*

For local display access, connect an HDMI cable between DCS2 and a monitor before powering on.

### 4. Apply Power

Connect the power supply to VDD\_MAIN. The board will begin booting automatically.
