Re: Part number for flex connector? Flex jumper details?

I think we have a misunderstanding. I'm looking for the actual part no. of the connector used on the display interface board because I want to know the type of plating which is on the contacts.

Thanks,
Scott

Re: Part number for flex connector? Flex jumper details?

I'm not sure which board is shown in that photo, but it's not the display driver board. The latter is what I need to know about, since that's what we are using.
Thanks,

Part number for flex connector? Flex jumper details?

Hello, I'd like to know the part number of the flex connector on the display interface board. I'm looking for the 15-pin, 1 mm pitch connector which is used to connect to a Raspberry Pi, not the connector for the display flex itself. A BOM for the board doesn't appear to be publicly available, but I...

Ah, excellent! It wasn't clear from the schematic which I2C buses those were.

Re: Which Compute Module 3 pins for I2C bus to R-Pi Display?

Sorry to bring this up again, but I want to confirm one detail: is it true that the CM3 has pull-ups on those I2C signals? Or, since the I2C signals can be mapped to different GPIOs, are we responsible for putting the pull-ups on our host board? Looking at the various schematics for the CM3, the CMI...

Which Compute Module 3 pins for I2C bus to R-Pi Display?

Hello, Please forgive what may be a duplicate question, but I've been searching the forums and yet am still unsure of the answer to the question of which pins on the SODIMM socket holding a Compute Module 3 should be used for the I2C interface to the official R-Pi Touch Display. We want to use whate...
