houkimeWhat is known about display?01:41
houkimealso, https://www.molex.com/molex/products/datasheet.jsp?part=active/5000246471_PCB_RECEPTACLES.xml&channel=Products01:42
houkimedisplay connector is obsolete01:42
houkimehirose DF30 and DF37 families look more likely compatible than modern molex, but they don't have 64 pins.02:57
houkimeit might be possible to plug a shorter header into a longer receptacle, but i am not sure about that.02:59
OksanaInteresting solderless board-to-board connector... https://www.airborn.com/products/connectors/rz-series-home-page06:46
Oksanahoukime: 0.40mm Pitch Board-to-Board SlimStack Receptacle, Surface Mount, Dual Row, Vertical, 0.95mm Mated Height, without Friction Lock, 64 Circuits ? There is https://www.molex.com/molex/products/datasheet.jsp?part=active/5024266412_PCB_RECEPTACLES.xml06:52
OksanaNew part is 0.40mm Pitch SlimStack Board-to-Board Receptacle, Surface Mount, Dual Row, Vertical, 1.00mm Stacking Height, with Solder Tabs, 64 Circuits06:52
OksanaSo, the difference is: 1) 0.05mm taller? 2) somewhat different locking mechanism? 3) slightly more durable - 30 mating cycles max vs 10 cycles old; 4) 3 times more current could go through; 5) what else?06:56
OksanaProblem is, worrying about this connector means also having to manufacture flex cables anew.06:57
houkimeOksana, well, you can compare the "drawings" (linked from a datasheet) for original connector ond the new you proposed and see that old is 5 mm wide while new is 2.6 mm wide11:19
houkimeThis is why i said that hirose series might be more compatible.11:19
houkimehere is the link for an original drawing http://www.molex.com/pdm_docs/sd/5000246471_sd.pdf11:28
houkimeIf there is no compatible receptacle for a display header then it means that likely replacing the whole display will be cheaper than making a custom flexpcb adapter.11:45
houkimei don't know much about how market from obsolete parts works though.11:45
houkimeOne more scenario is to desolder a connector from N900 board and transplant it to the new one.11:46
houkimebut obviously not much room for error with this one.11:47
houkimeJoerg-Neo900, any thoughts?11:49
houkimeAlso, about transplantation, is the N900 connector actually identical to molex in the neo900 schematics or it can have a bit different footprint?11:52
DocScrutinizer05we got more displAY CONNE13:32
DocScrutinizer05we got more display connectors than display "mech parts", so a non-issue13:32
DocScrutinizer05we did quite some artistics to find and finally source those display connector parts13:33
houkimeok, great14:18
houkimeCan't find a datasheet on  ACX565AKM LCD23:43
houkimeAnyone knows where to fetch one? Sony seems like a very strange company which doesn't distribute documentation on its own parts.23:44
houkime( ACX565AKM  is  an LCD used on N900)23:45
houkimethe pin names on the display connector are based on _something_, right? Some document?23:55
houkimeFor example, here is the question: what is the speed of display SPI bus?23:57
