[19:01:23] <adj_> anyone know the maximum frequency of 2.54mm and 1.27mm pin headers on lime and other olimex boards?
[19:02:17] <adj_> I'm interested on the frequency of the connectors, not the olimex boards' interfaces
[19:08:23] <DKordic> adj_: I can not remember what should the ``frequency of the connector'' be.
[19:33:21] <lukas2511> adj_: if you want to know what the chips can do you'll have to read the datasheets, if you want to know what frequencies you can actually push just through those pinheaders... if designed right they probably can do some hundreds of mhz without any problem, but if you are at those regions of frequencies you should consult an expert™
[20:39:33] <adj_> lukas2511, yes, my question was about the max frequencies through the pin headers
[20:40:54] <adj_> I have not been able to find this information online
[20:53:50] <lukas2511> adj_: it really depends on how you use them. how you arrange your data-lines can make a big difference in impedance and capacity, and with that the maximum frequency you can put through there.
[20:54:35] <lukas2511> also generally if you use differential pairs you can go a lot higher than with just single connections
[23:11:41] <Samysam> Hi all. I'm looking for a screen and a board. I found a post recommending this one: goo.gl/pl1mIU (5' capacitive). Anyone has a good tutorial to start at ? Do I need a controller board ? Is it compatible with all olinuxino board ?
[23:16:41] <xcasex> Samysam: just buy what's on the olimex webshop :)
[23:18:58] <Samysam> there's no 5 inch capacitive screen on the shop
[23:21:57] <xcasex> you are quite right Samysam but there's this 4.3" https://www.olimex.com/Products/OLinuXino/LCD/LCD-OLinuXino-4.3TS/open-source-hardware
[23:22:00] <xcasex> with touch.
[23:22:09] <Samysam> yes, but resistive
