單板電腦
除了同時包含微控制器與 SoC 的開發板之外，另有一種稱為單板電腦（Single-Board
Computer, SBC）的硬體電路開發板，也可執行 Node.js。單板電腦在一塊電路板上，整
合各種電腦周邊設備，諸如顯示卡與記憶體。此種裝置距離 Arduino 已非常遙遠，反而
與你的筆電或桌機較為相像。
Raspberry Pi 是廣為人知的單板電腦之一，Intel Edison 也算是單板電腦，整合了 WiFi
與藍牙通訊功能等周邊。
若想使用單板電腦，通常代表著你需要付出額外的心力，花時間安裝作業系統、並且設
定網路組態，想要讓一台單板電腦開機且正常運作，很快地就會變成一項挑戰。幸運的
是，許多高手常常樂於分享經驗並撰寫教學指引，放在網路上分享給大家。若你曾經開
發過網頁應用程式，那麼，就會覺得設定一台單板電腦的工作，有些許類似於伺服器的
管理事務。
一旦作業系統成功開機，而且網路連線也暢通無阻，接著要為單板電腦裝上 Node.js 的
任務，反而是簡單的部分，小事一件。
Raspberry Pi
諸如 Raspberry Pi 這種單板電腦產品，所需耗用的電流較大（300~500 mA），比起微控
制器（10~30 mA）高出甚多。若想採用 Raspberry Pi，必須確保電源變壓器能負擔處理
器龐大的電流需求，除了要準備適當的電源供應器，還要有一條 HDMI 線材連接顯示
器、以及 USB 鍵盤與滑鼠，以便存取裝置。
對於網路連線與多媒體操作體驗，Raspberry Pi
