Single Board Computers

单板机,简称(Single Board Computers)是将一台完整的计算机的组装在一块印制电路板上,包括(多个)微处理器/存储器/输入输出接口,还有其他计算机必备的外部设备。单板机适于进行生产系统的过程控制。也可以用于于教学系统。 如今,很多家用电脑或便携式电脑都把功能集成到一块PCB电路板上。

差异主要在于组件所在介质是不同的:

3. 可以自己安装Linux系统的单板机

3.1. Raspberry Pi

树莓派(英语:Raspberry Pi),是一款基于Linux系統的只有一张信用卡大小的单板机计算机。它由英国的树莓派基金会所开发,目的是以低价硬件及自由软件刺激在学校的基本的电脑科学教育。

3.2. Arduino

Arduino is a single-board microcontroller designed to make the process of using electronics in multidisciplinary projects more accessible. The hardware consists of a simple open source hardware board designed around an 8-bit Atmel AVR microcontroller, though a new model has been designed around a 32-bit Atmel ARM. The software consists of a standard programming language compiler and a boot loader that executes on the microcontroller.

Arduino boards can be purchased pre-assembled or do-it-yourself kits. Hardware design information is available for those who would like to assemble an Arduino by hand. It was estimated in mid-2011 that over 300,000 official Arduinos had been commercially produced at that point.

3.3. BeagleBone

The BeagleBoard is a low-power open-source hardware single-board computer produced by Texas Instruments in association with Digi-Key. The BeagleBoard was also designed with open source software development in mind, and as a way of demonstrating the Texas Instrument's OMAP3530 system-on-a-chip.[5] The board was developed by a small team of engineers as an educational board that could be used in colleges around the world to teach open source hardware and open source software capabilities. It is also sold to the public under the Creative Commons share-alike license.
