Overview of the Developer Kit
Precautions - read before operating
- The developer kit may become hot during use. Do not touch heatsink during or right after use
- USB Type A ports are not meant for charging other devices
- The developer kit should not be set on a conductive surface. Pins on the underside of the carrier board will short, damaging the developer kit
- The microSD Card slot has push - push mechanism. Push the first time to lock card in. Push again to release the card and remove it.
Developer Kit Setup
Before using your developer kit, you need to set up a microSD card with the operating system and JetPack components. The simplest method is to download the microSD card image and follow instructions found in Getting Started with Jetson Nano 2GB Developer Kit .
You'll need to supply the microSD Card (UHS-1 32GB minimum) and a USB-C power supply (5V⎓3A).
microSD Card lifespan is a consideration when using a swap file. High endurance and/or larger capacity microSD Cards are recommended
Setup via SD Card Image (Recommended)
The recommended way to setup your developer kit involves downloading a system image and writing it to your microSD Card. Simply follow the instructions available in the Getting Started Guide
Setup via NVIDIA SDK Manager
NVIDIA SDK Manager is a graphical tool for use on a Linux host computer (running Ubuntu 18.04 or Ubuntu 16.04). It provides a menu based method for installing JetPack on a Jetson developer kit. Using this tool is a more involved way of setting up your Jetson developer kit, but it allows you to also install JetPack components on the host computer for cross compilation purposes. To get started quickly with your developer kit, we recommend the SD card image method linked above.
If you want to use SDK Manager, please refer to the SDK Manager documentation .
Headless mode is handy when you don’t have a display around (or for some special purposes). After setting up in headless mode, you can use the developer kit either via network connection or simply by connecting it to another computer with a Micro USB cable.
If no display is attached to the developer kit during first boot, the initial configuration process will be headless. You will need to complete initial setup via serial application (e.g., puTTY) on another computer connected to the developer kit’s Micro-USB port.
Refer to instructions here for headless mode setup.

40-Pin Header (J6)
The 40-pin header provides access to power, ground, and interface signal pins.
There are two 3.3V power pins and two 5V power pins. These are not switchable; power is always available when the developer kit is connected to power.
- The two 5V pins can be used to power the developer kit at 2.5A each. (Do not power the developer kit via these pins and USB-C connector at the same time.)
Interface signal pins
- All signals use 3.3V levels
By default, all interface signal pins are configured as GPIOs, except those supporting I2C and UART
Jetson.GPIO offers an easy way to control GPIO pins. Jetson-IO can be used to reconfigure pin functions, e.g., from GPIO to SFIO (Special Function I/O) such as I2C, I2S, etc . Both Jetson.GPIO and Jetson-IO are already included in JetPack.
Note that the I2C interface pins are pulled up with 2.2kohm resistors to 3.3V. All signals except the I2C interfaces connect to the SoC through Texas Instruments TXB0108RGYR level shifters. See " Jetson Nano Developer Kit 40-Pin Expansion Header GPIO Usage Considerations " for more information on these level shifters and how to work with signals that connect to them.
12-Pin Button Header (J12)
This header provides GPIO to control the power state of the board. Enclosures for the developer kit can connect to this header.

4-Pin Fan Header (J7)
The pinout of the 4-pin fan control header at location J7 is shown below.
Initial units of the Jetson Nano 2GB Developer Kit without wireless networking adapter (PN: 945-13541-0001-000) do not have a fan header already stuffed at J7. See Fan Header Installation below if you have a developer kit without fan header and you want to install one.
The header can support either a 3-pin fan connection (GND, PWR, and TACH) or a 4-pin fan connection (GND, PWR, TACH, and PWM). Using a fan with PWM capability allows software to adjust the speed of the fan as needed. Only 5V fans are supported.
|4||PWM (Pulse Width Modulation)|
Controlling the fan
Fan can be controlled through PWM.
Check the L4T Fan control documentation
If you want to add a fan to the system, please select a 5V fan that:
- Uses a standard ATX fan connector
- Follows the ATX fan pinout
- Has 40mm x 40mm screw spacing for connection with the developer kit heatsink
Fan Header Installation
If you have a developer kit without fan connector, you can solder a suitable connector to the carrier board as shown below. Select a keyed connector that will work with either 3-pin or a 4-pin fans. S ee this example fan connector search .
The figure on the left shows where the connector is to be installed. Be sure to install with pin 1 in the correct place as shown. As example, the figure on the right shows a fan header installed in a Jetson Nano Developer Kit carrier board.
The developer kit supports USB-C power supplies of 5V ± 5%, 3A. If your phone uses a USB-C power supply, there is a chance that it is enough to power the devkit. Check its specifications.
For a list of validated power supplies, consult our Supported Components List .
If the voltage drops below 4.25V, the system will shut down.
The Jetson Nano 2GB Developer Kit cannot be powered via the Micro-USB connector.
The developer kit’s total power usage is the sum of carrier board, module, and peripheral power usage, as determined by your particular use case.
There are two software-defined power modes for the Jetson module. The power mode can be switched with the UI interface at the top right of the desktop, or by following the L4T Power Management guide.
The two module power modes are:
- 10W - default mode for more performance
- 5W - suggested for less energy use
See the L4T power management guide for more details and instructions about how to create your own power mode.
Power via 40-pin Header
The developer kit can be powered by connecting the 40-pin header's 5V pins to an external power supply, Each of the two pins will support 2.5A.
Do not power the developer kit via 40-pin header pins and USB-C connector at the same time.
Battery Powered Operation
For applications which require the developer kit to be run on a battery (like JetBot), we suggest using a USB-C power bank.
Be sure to use a battery which can sustain voltage above 4.25V, else the system will shut down.
The developer kit supports wired and wireless networking:
- Wired - Ethernet will be available as soon as a cable with network connection is plugged into the RJ45 port
- WLAN - Wireless networks will be available after plugging in a supported USB wireless networking adapter
- WPAN - Bluetooth will be available after plugging in a supported USB Bluetooth adapter
Available networks can be discovered through the networking icon at the top right corner of the desktop or via System Settings. To change any default networking configurations please use the Settings page.
Any wireless networking or Bluetooth adapter should be connected to the USB 3.0 port (the single USB port that is not stacked) for better performance. An extension cable is suggested in order to reduce EMI interference between USB networking adapter and the developer kit.
Ethernet Port LED Behavior
The Ethernet port has two LEDs:
- Green LED : is on if a GigabitEethernet connection is active. The LED is off if no Ethernet connection is active, or if a connection with speeds lower than 1 gigabit per second is active
: flickers if there is traffic flowing through the port
