Raspberry Pi Computer
Raspberry Pi Computer
Information
Name: Raspberry Pi 1+ Model B (2014).
Comments: small computer, size of about one mobile phone without a case or size of about two mobile phones with a case. There is no hard drive and you need a certain kind of SD or SDHC card. You can use a mobile phone's power adapter for power, 5 V and at least 700 mA (3.5 W) recommended for model B. Do not hotplug USB devices or Raspberry Pi (model B) may restart. Instead, use a powered USB hub if you like to hotplug devices often while the power is on. I personally use the micro-USB to USB cable from X10 Mini power adapter to connect from Raspberry Pi to the USB hub, so there is one less power adapter plugged to the wall. Originally intended for educational use, but you can use this for example to test your net connection, use as a file server for music files, etc.
