what about a standard for categorising the different cards based on there computer resources/speed. like sd cards classes. so speed class 1 if no use 2 only usb 1.* speed class 2 usb 2 less than 1ghz & less than 1gb ram speed class 3 usb 2 more than 1ghz & 1gb ram speed class 3 usb 2 more than 1ghz & 1gb ram gb ehternet ...etc multimedia class SD only capable of sd video multimedia class HD (720) only capable of HD video multimedia class Full HD (1080) only capable of Full HD video gaming class 1 old games upto games form mid 2000's etc for the question what class for video editing multimedia class full hd and speed class 5 Or what about making it only 1 class to worry about?: gaming g1 old games g2 newer games g3 lastest games multimedia mm 1 = music playback mm 2 = basic audio editing mm 3 = advanced audio editing mm 4 = sd video playback mm 5 = hd (720) video playback mm 6 = full hd (1080) video playback mm 7 = sd video editing mm 8 = hd (720) video editing mm 9 = full hd (1080) video editing generic g1 upto 6webpages at a time minamul multi tasking text documents g2 upto 30 web pages at a time g4 upto 80 webpages at a time etc This is just a suggestion on of what it might look like.

http://rhombus-tech.net/allwinner/a33/news/ well i received the documentation middle of last week, i basically started yesterday evening and am almost 50% done already! the a33 would be the first quad-core cpu card, with 2gb RAM. can't do much about etherhet, it has to be an SMC9514. but that's pretty awesome. l.

more revisions to the interface, these are last-minute just before finalising: * the revision 2.2 A20 cpu card * the revision 0.1 ICubeCorp IC1T cpu card * the revision 0.1 Ingenic JZ4775 cpu card * the revision 0.1 Micro-Desktop base board * the revision 3.0 Tablet / Mini-Laptop base board * also i have received the documents for the quad-core Allwinner A33 so will be starting a CPU card for that with 2GB RAM, shortly. i will have enough money coming in beginning of this month to send the revision 2.2 A20 CPU Card off to the factory for 5 samples. the revision 0.1 Micro-Desktop will follow very shortly after that. the IC1T icubecorp found me an SD-based TSOP-48 from a company called FORESEE, which comes in a low-cost 2GB variant. i will add that in (replacing the BGA variant which is 4Gb minimum, requires very small tracks, is more expensive and is making me nervous). the jz4775 cpu card i had to do a minor shuffle of the I/O lines as there was some I/O multiplexing sharing SPI with MMC so there is a bit more work there. heck of a lot going on, it is ironic that about four really good CPU cards should all come out pretty much at the same time... l.

tablet/laptop pcb rev3
by Luke Kenneth Casson Leighton 24 Jul '14

24 Jul '14

ok opportunity with the cpu card interface redesign to do a layout change, i'm taking out the atsam4s and replacing it with a VC0345 camera IC, PCA9536 I2C-to-GPIO converter, and am putting in a Micro-SD on the top edge of the PCB (so that things like the IC1T card can use it). ethernet and the extra USB i will route to an FPC which can go to a daughterboard for when this is used in a mini laptop. USB audio remains as-is using the CM108AH. basically the tablet pcb becomes a usb / i2c peripheral board, something i didn't want to do because i wanted the educational and experimentation sector covered as well. l.
