當你收到Jetson Nano

Included in the Box

盒子裡有

Your Jetson Nano Developer Kit box includes:

  • Jetson Nano Developer Kit
         一片開發板
  • Small paper card with quick start and support information
         關於quick start and support information的紙卡
  • Folded paper stand
         折起來的紙架

Items not Included

盒子裡沒有但是你應該要用到的

You’ll also need:

  • microSD card (16GB UHS-1 minimum)
  • USB keyboard and mouse
  • Computer display (either HDMI or DP)
  • Micro-USB power supply (5V⎓2A)

Prepare for Setup

Items for Getting Started

microSD Card

Jetson Nano開發板需要使用microSD卡當作開機設備,而且要夠大夠快以符合你的專案需求:因此建議最少要16GB UHS-1 card.

The Jetson Nano Developer Kit uses a microSD card as a boot device and for main storage. It’s important to have a card that’s fast and large enough for your projects; the minimum recommended is a 16GB UHS-1 card.

See the instructions below to flash your microSD card with operating system and software.

Micro-USB Power Supply

你會需要提供一個品質夠好的5V-2A電源供應器給開發板.並非所有額定電壓為“5V⎓2A”的電源供應器都會達到此目的.(已經有不少人在這裡敗下陣了)

You’ll need to power the developer kit with a good quality power supply that can deliver 5V⎓2A at the developer kit’s Micro-USB port. Not every power supply rated at “5V⎓2A” will actually do this.

做為一個夠好的電源供應器,NVIDIA驗證了這款5V 2.5A Switching Power Supply with 20AWG MicroUSB Cable.他是特別設計用來克服USB電源供應器常見的問題的,詳情請看連結.

As an example of a good power supply, NVIDIA has validated Adafruit’s 5V 2.5A Switching Power Supply with 20AWG MicroUSB Cable (GEO151UB-6025). It was specifically designed to overcome common problems with USB power supplies; see the linked product page for details.


Optional Items

選配

Wireless Networking Adapter

無線網路配接器

Jetson Nano Developer Kit includes a gigabit Ethernet port, but also supports many common USB wireless networking adapters, e.g., Edimax EW-7811Un.

Nano開發板已經有一個gigabit網路孔了,還是支持常見的USB無線網路配接器,像是Edimax EW-7811Un.


Write Image to the microSD Card

把映像檔寫到microSD卡

To prepare your microSD card, you’ll need a computer with Internet connection and the ability to read and write SD cards, either via a built-in SD card slot or adapter.

準備好你的microSD卡外還需要一台能連上網的電腦而且要能夠透過SD卡插槽獲配接器讀寫SD卡.

  1. Download the Jetson Nano Developer Kit SD Card Image, and note where it was saved on the computer.
從這裡下載jetson-nano-dev-kit-sd-card-image,並且記得它存在哪裡.
2.Write the image to your microSD card by following the instructions below according to the type of computer you are using: Windows, Mac, or Linux.
根據您使用的電腦類型，進入以下連結說明將映像檔寫入microSD卡：Windows，Mac或Linux。


Setup and First Boot




Setup Steps

  1. Unfold the paper stand and place inside the developer kit box.
展開紙架並放入開發板盒內。
     2.Set the developer kit on top of the paper stand.
         將開發板放在紙架頂部。
     3.Insert the microSD card (with system image already written to it) into the slot on the underside of the Jetson Nano module.
         將microSD卡（系統映像已寫入其中）插入Jetson Nano模組底部的插槽中。

     4.Power on your computer display and connect it.
        打開顯示器電源並連接它。
     5.Connect the USB keyboard and mouse.
         街上USB鍵盤和滑鼠.
     6.Connect your Micro-USB power supply (5V⎓2A). The Jetson Nano Developer Kit will power on and boot automatically.
        接上Micro-USB電源供應器(5V⎓2A).Jetson Nano 開發板會自動開機啟動.


First Boot

A green LED next to the Micro-USB connector will light as soon as the developer kit powers on. When you boot the first time, the Jetson Nano Developer Kit will take you through some initial setup, including:

開發板開機後，Micro-USB連接器旁邊的綠色LED指示燈將亮起。

  • Review and accept NVIDIA Jetson software EULA
         查看並接受NVIDIA Jetson軟件EULA
  • Select system language, keyboard layout, and time zone
         選擇系統語言，鍵盤佈局和時區(我會建議選擇英文,因為不知道會不會有檔案夾用中文命名 而必須在命令列模式切換移動這類狀況)
  • Create username, password, and computer name
         建立用戶名，密碼和電腦名稱
  • Log in
         登入

After Logging In

You will see this screen. Congratulations!

你會看到這個屏幕。恭喜！
