Not sure how I missed this the first time around but stumbled on it after looking for info on the mailing list..
:) good to hear from you.
Saving money is good but Pandora 2 is not going to be in a race to the bottom. A10 barely offers anything over the current DM3730 Pandoras.
exophase...
btw i'd like people to know that i'll be happy to continue doing the schematics and PCB design layout... if people express an interest in seeing this happen. just as with the original openpandora, you help pick the design that you'd be happy to pay for, and i'll help make it happen.
yep. although i'm told informally that the die itself does have HDMI out, they wanted to stay ultra-low cost ($5) and not compete with the A10. putting on 25 more pins would have pushed them up to a larger QFP - bigger than the designers were comfortable with but, the 16-bit data lines to...
wotcha mr exophase. yeah i took that into account, and am using PWM instead. the pricing i found for the 72mhz 100-pin STM32F is *two* dollars and thirty six cents in 10k volumes. $2.36! i can't possibly justify a $2 codec IC at that kind of pricing!
but, yeah: all a bit of an...
ok i took a look at the poll results - it looks like people are gravitating towards 16:9 ratio 5in size LCDs with a minimum of 720 pixels on the vertical. a quick search on panelook shows this...
the A10 is actually extremely good value-for-money. it's a 1ghz ARM Cortex A8, which can be pushed to 1.2ghz with no difficulties, and it's $7.50 in 100k quantities. it has a 32-bit DDR3 RAM interface that can go up to 800mhz (1gbyte of 800mhz DDR3 RAM is only $4 in 10k volumes).
if you've...
ok, so here's some very quick hacked-up schematics and a PCB layout, based on the Flying Squirrel Tablet (for the KDE Plasma Team). full schematics are available, as well as PDFs and a PNG of the layout for those people who don't have the PCB software:

that's why i mentioned that team in mexico who are designing a 5in hand-held games console: it *can* be done. the CPU Card is only 5mm high, and each of the three i've been working with is packed ultra-densely with components. Amphenol's socket is 6mm in height; i did track down one that...
are you *sure* about that? :) a dual-core 1.2ghz Cortex A7 isn't good enough? a quad-core iMX6 isn't good enough?? and future CPUs aren't good enough?? that's the whole point of the exercise - that it's future-upgradeable [with no future design costs for the openpandora team]

folks hi,
i've not posted too often here but the open nature and the active community of the openpandora means that i learned a great deal in taking forward the projects that i'm working on. i've also held off from posting here until there's something a little more concrete. background links...
ok, i'm reviving this thread as the A10 EOMA-68 CPU Card now has an active team working on it: http://rhombus-tech.net/allwinner_a10/news/
that means that there will soon be a CPU Card in credit-card-sized format which can be plugged into any chassis with an I/O Board. laptop, desktop, tablet...
yes, that's us. http://rhombus-tech.net. you're marginally off at "being offered at $15/each". i said the *target* for the *BOM* is $USD 15 in *mass-volume*, for a PCB with near-identical functionality to the rbpi. slashdot added the words "steal" and "thunder" without my consent to the...
mmm... don't know. the chinese way doesn't really involve documenting things very accurately, although i gather this isn't something that's unique to chinese engineers :) if it sells in volume in the PRC because the price is good, it sells in volume because the price is good - why should they...
yeah i hear rumours of people hacking the firmware (without any documentation or advice from the SoC vendor), cranking them up to 1.5ghz and finding that, surpriiise, they don't work. the problem is that if it _is_ possible, it's necessary to increase the CMOS voltage supply. the Reference...
yes, exactly. there are thousands of bits of plastic already out there: there's absolutely no need to spend $100k on case-work for something that already exists [the lesson learned from the openpandora...]
i got a quote from a designer in china to create the motherboard (LCD backlight, battery...
ahh, yes - i know them, and love what they've done. they have two modules. S5PC110 (1ghz Cortex A8) and an S5PC210 (enyxos 1ghz Dual A9). the problem is
hardkernel modules are not user hot-swappable. the design we've done is.
hardkernel's modules are not inter-incompatible (you can't take...
acchhh... exophase, i have to cut this into two: the forum says i have "exceeded the allowed number of quoted blocks of text, can you believe it? pah.
*click*... i am, aren't i? :) where the hell did i get 850k from? i think i been staring at too many web site specs yesterday...
i spoke to...
sorry exo i missed this earlier:
ah c'moon, exo - have you seen the specs on 3G / GSP modules such as the ones from Telit? they only do 12-bit sampling @ 8khz because the GSM protocol can't get the data to the other end any better than that :)
