5. What’s PI
it is for studying
computer for K12 -
how computer works
and how to study
‘PITHON’,easy and
basical lang.
works
Debian,Arclinux...and
Android
6. There are Revisions
Rev.A - without ethernet (using usb)
Rev.B 1.0 - with ethernet
Rev.B 1.0 + ECN0001 (no fuses, D14 removed)
- ? Perhaps we cant see in Japan
Rev.B 2.0 - adding some improvements
Rev.B 2.0 w/512MB - adding memories Latest!
7. 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
8. Two Vendors for PI
RS Components - manufactured in China.Now
can order from Japan but it takes 2-3 month
to get them :-(
Element14 - manufactured by Sony in UK.but
no channel reseller in Japan (now talking
with CPC,sis company of element14 ),it take
1-2 week to get them :-)
11. Needs enough to pack
10/100 ethernet - enough to work with
electric power.
no wifi - wifi eats electric power - sometime
it wont boot actually with usb wifi (be
carefull :-p)
poor memories,CPU - it is for COST :-p
12. GPIO Port
You must check using PI serial line provided
by GPIO NOT USB port.
GPIO port assign very often changes
updating the Revision of PI.
root MUST NOT permitted for ssh by default
Prepare Sparkfun DEV-09873 (3.3V NOT 5V)
careful 115200 bps to be used for serial

15. Be careful using
Need stable power running USB wifi.
Need high-speed and stable SD card to
running OS
Use high-power and stable battery like
Panasonic to use PI as mobile. (in my case it
works for 8 hours)
be careful USB port on Mac....often got
kernel panic.(say abusing USB port)

17. 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/
RevB
Now
19. 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?
20. cf. Raspbian “wheezy”
Default Destro.recommended OS
Works good but veeery slow GUI,be careful
Poor CPU,memories must be considered
