# Overview & Specification

## **Features**

* Fully compatible with Jetson Orin NX/Nano
* Combines the power of Pixhawk & Jetson in a small form factor
* [**Pixhawk Bus (PAB) open source specification**](https://github.com/pixhawk/Pixhawk-Standards/blob/master/DS-010%20Pixhawk%20Autopilot%20Bus%20Standard.pdf)
* Jetson & controller are connected via UART, CAN, and Ethernet Switch

{% hint style="info" %}

#### Jetson Xaviar NX and Jetson Nano are not compatible.

#### This baseboard will function as a Jetson Carrier without the Flight Controller

{% endhint %}

## Jetson Orin NX/Nano Connectors

* Gigabit Ethernet  
  * Connected to both Jetson & controller via Ethernet Switch (RTL8367S) - 8-pin JST-GH - RJ45
    * Ethernet port & switch powered by the circuit as the Pixhawk

  * PCIEx4
* M.2 Key E 2230 for WiFi/BT
  * PCIEx2
  * USB
  * UART
  * I2S
* Mini HDMI Out
* 4x GPIO
  * 6-pin JST-GH
* CAN Port
  * Connected to the controller’s CAN2 (4 Pin JST-GH)
* SPI Port
  * 7-Pin JST-GH
* I2C Port
  * 4-Pin JST-GH

  * 1 connected to the controller’s telem2
* Fan Power Port
  * Current limit 0.35A
* IIM42652 IMU
* Input Power
  * XT30 Connector
  * Voltage Rating: 7V-24V (2S-5S)
  * Separate the input power circuits from the controller to ensure flight safety
  * Holybro UBEC can be used for applications above 4S
  * **Note:** The Pixhawk Jetson Baseboard has an integrated UBEC to convert 7V-24V to 5.0V for the Jetson. Using an external UBEC alongside the integrated one provides redundancy and easier replacement in case of BEC failure.
* Power Requirements
  * Depends on Usage and Peripherals, minimum \~15-30 watts
