Re: OLPC XO 1.75 replace one of the 3 usb port with a mini hdmi

We finally took your suggestion on XO-4. When students or teacher give talks it would be nice for them to show to the class on the tv what they are doing. The type hdmi 1.4 , D connector is 2.8 mm × 6.4 mm, where as the hdmi 1.3 type C connector is 2.42 mm × 10.42 mm; for comparison, a micro-USB connector is 2.94 mm × 7.8 mm and usb a is 11.5 mm × 4.5 mm. http://en.wikipedia.org/wiki/HDMI#Connectors Looks like the ARMADA 610 has support for hdmi 1.3 http://www.slashgear.com/marvell-armada-610-app-processor-1080p-hdmi-3d-graphics-more-0567682/ As does it's successor, the PXA2128, used in the XO-4 and XO-4 Touch. Also I hope there is a give1get1 one for this machine along with a nice touch screen :) There is a touchscreen on the XO-4 Touch. We are thinking of ways to increase availability of these. Maybe a usb header on the motherboard, along with pcie mini card a boy can dream. There is a spare USB port on the motherboard, although it is accessible on resistor pads, not a connector. Sorry about the mini-PCIe --- we use that connector for the WLAN but it only has SDIO and USB. Cheers, wad ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

BTW, does 1.75 board still fit into XO-1 like the 1.5 one does? Yes, except there's a slight mod required to secure the wifi but that's the same mod that's required to mount a 1.5 MB in a 1.0 case too. 1.75 in a 1.5 case should be fine. There was a post to the list in the last couple of days about a 1.5 MB in a 1.0 case and what minor mod was required. We have a metal bracket designed and in production which makes that even more trivial. Unfortunately, doing this also requires adding some conductive foam/tape in a number of places in order to maintain the same ESD protection as the XO-1.

Most of the schools I've seen with XOs have no TVs, much less one with HDMI input. The HDMI pins aren't reused for anything, so this IS theoretically possible. We didn't budget for HDMI power, however.We'll think about it. wad ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
