There are RevisionsRev.A - without ethernet (using usb)Rev.B 1.0 - with ethernetRev.B 1.0 + ECN0001 (no fuses, D14 removed)- ? Perhaps we cant see in JapanRev.B 2.0 - adding some improvementsRev.B 2.0 w/512MB - adding memories Latest!
Check your Rev.*cat /proc/cpuinfo Model and revision Code(s) Model B Revision 1.0 2 Model B Revision 1.0 3 + ECN0001 (no fuses, D14 removed) Model B Revision 2.0 4,5,6 Model B Revision 2.0 (512 MB) 13,14,15
Two Vendors for PIRS Components - manufactured in China.Nowcan order from Japan but it takes 2-3 monthto get them :-(Element14 - manufactured by Sony in UK.butno channel reseller in Japan (now talkingwith CPC,sis company of element14 ),it take1-2 week to get them :-)
Needs enough to pack10/100 ethernet - enough to work withelectric power.no wiﬁ - wiﬁ eats electric power - sometimeit wont boot actually with usb wiﬁ (becarefull :-p)poor memories,CPU - it is for COST :-p
GPIO PortYou must check using PI serial line providedby GPIO NOT USB port.GPIO port assign very often changesupdating the Revision of PI.root MUST NOT permitted for ssh by defaultPrepare Sparkfun DEV-09873 (3.3V NOT 5V)careful 115200 bps to be used for serial
Be careful usingNeed stable power running USB wiﬁ.Need high-speed and stable SD card torunning OSUse high-power and stable battery likePanasonic to use PI as mobile. (in my case itworks for 8 hours)be careful USB port on Mac....often gotkernel panic.(say abusing USB port)
Poor CPU and Memories ed... lea s taking care of memories and en re CPU. be as top,such as measuringB hperformance - must 12 M use for sizing 5 w/ RevBNow
Rasroid now developing Rasroid Project: http://androidpi.wikia.com/ wiki/Android_Pi_Wiki Works......orz Broadcom (Eben now working for as a Director) working on Android 4.0(ICS) for Raspberry PI,now a bit problem on it.have to be ﬁxed (sounds doesnt work..) but works on 256M..512M..1G?
cf. Raspbian “wheezy”Default Destro.recommended OSWorks good but veeery slow GUI,be carefulPoor CPU,memories must be considered
