BeagleBone Black决战Raspberry Pi
许多博客和新闻网站都吹捧BeagleBone Black是Raspberry Pi的杀手,真有其事吗?
比较一下硬件规则说明大概就明白了。

Raspberry Pi
Notes
Cost45$35$ model BThe beagle black costs more, but keep reading! There is a good reason for the extra 10$
RAM 512 DDR3600 Mhz 512 SDRAM This one is close but the beagle black is pushing a higher ram speed
Flash 2GB & SD card SD Card slot The flash on the Beagle Black allows an operating system to be added without an SD card. Beagle wins this one.
Processor 1GhzAM3359 700MhzBCM2835 Some people have clocked the Pi up to 1Ghz but its pretty risky. The Black runs great at 1Ghz. No news yet one how much overclocking it can do though.
Ethernet 10/100 Mbs 10/100 Mbs Solid Tie
USB 1 client1 host 2 host Not having two ports on the Black is a little rough. It makes using a keyboard and a mouse pretty difficult. But then again, most PI setups are using a USB hub anyway. Still, the Pi wins this one.
Video HDMI HDMI, AV Both boards will put out 1080. The Pi wins this one for having the AV out. This comes in handy when your resources are very limited.
Audio Via HDMI Via HDMI
Audio Jack The PI wins here. Without the audio jack on the Beagle the capabilities as a multimedia system are limited.
Periperals SPI, I2C, SPI, CAN, Timers, LCD, MMC, Analog 8 GPIO
1-USART
1-SPI
1-I2C Hands down the Black has this one in the bag. For robotic and automation development the beagle bone is a far better option. One hindrance is the lack of analog ports on the PI,
Power USB 5v
DC Jack
210ma & idle The Black use let power at idle, however this is completely dependent on your setup. For robotic development the lower power consumption is very handy in battery powered applications. The DC jack also allows connection of a battery without an external regulator. 资料来源:http://roboteurs.com/beaglebone-black-vs-raspberry-pi/
总的来说,Beaglebone Black拥有比较快的处理器,更多的I / O,内建flash memory,同时支持Android和Linux,包括Ubuntu。视频解码能力就不如Raspberry Pi,且没有composite输出(RCA TV输出)。
如果需要一个高清摄像头,高清视频播放,最好选择Raspberry Pi。对于其他用途,Beaglebone Black应该是比较好的解决方案。
