Its name is a bit strange but Raspberry Pi is the common name of series of single-board computers. The creator of the Raspberry Pi has the same name as the board where it is the Raspberry Pi Foundation. The first version of the Raspberry Pi launched in 2012 with a configuration of 700 MHz CPU, 256 MB RAM. During time 4 more main configuration is released and named with numbers like Raspberry Pi 2, Raspberry Pi 3, Raspberry Pi 4, and low-cost version Raspberry Pi Zero. Raspberry Pi mainly designed to be cheap affordable SOC (single-board computer) which is priced around 25$ – 35$ for different versions.

Raspberry Pi專案目標 (

Raspberry Pi Project Objectives)

Raspberry Pi project is launched by a foundation which has some objectives in creating the Raspberry Pi SOC.

Raspberry Pi專案由一個基金會發起，該基金會的目標是建立Raspberry Pi SOC。

• Cheap: Raspberry Pi is designed to be cheap because everyone should easily afford it to use. Also being cheap makes it be used to build in different projects and products without cost restrictions. Making Raspberry Pi cheap also make it available around the world for different countries and poor communities.

  Cheap ：Raspberry Pi旨在便宜，因為每個人都應該負擔得起使用它的費用。 便宜也使它可以用於構建不同的專案和產品而沒有成本限制。 通過降低Raspberry Pi的價格，它也可以在全球範圍內供不同國家和貧困社群使用。

• Featureful: Raspberry Pi is designed to be featureful because it needs to be used in different projects with different features. Raspberry Pi should be used from weather applications to the projecting applications with its I/O pins and HDMI output. It should also connect different USB devices for expansion.

  Featureful ：Raspberry Pi旨在具有特色功能，因為它需要在具有不同功能的不同專案中使用。 從天氣應用到投影應用，應使用Raspberry Pi的I / O引腳和HDMI輸出。 它還應連線不同的USB裝置以進行擴充套件。
