Piecemealed Build

[crowboat]

Hi all, I just received my main board, screen, and heat sink from españa. It looks like I need to source ribbon cables for the connections myself, is there a standard size for these cables that I can buy, from amazon for example? Thanks kindly

Here is some recent discussion regarding Zynthian ribbon cables which included some Amazon links:

V5 not booting with control board plugged in

I am not at all sure about this, having only built V5 kits from stock parts, but looking at the picture from the V5 build instructions: [image] It looks like the Zynthian kit uses what MECCANIXITY calls a type B cable and you have gotten a type A. From your link: Two Kind of Types - A and B “A Type” flat cable means — the contacting side of the 2 top pin is on the same side(Both towards to up or down). “B Type” flat cable means — the contacti…

I don’t know whether it will actually help but it’s the easiest pointer I have handy.
You can look at the Zynthian Schematics and PCB Layouts and some BOM info in the Z hardware repo for more basic info.

crowboat welcome here

Old PC disk drive connectors from the dim and distant past always worked for me, but it’s a good idea to get some ribbon cable and some squeeze connectors and make your own. It allows to make test looms whilst building and then make properly sized ribbons for final installation.

Be careful with ribbon cable & 40 pin IDC connectors. It’s better to get the gray ribbon with a red trace. The rainbow colours can vary in size and some don’t fit. And always make sure the red trace is on the same pin. Don’t be fooled by putting a connector on opposite sides of the ribbon.

Oh, yes, Welcome! and offerings are dropped off in the normal place, when it’s all finished.

thanks kindly all, I found the wiki assembly page and have ordered the type B connectors and a DSI display cable.

Since the control board being out of stock is the main reason why I’m not using a full kit, I’m hoping to use some spare key switches to make the button interface.

I have received my cables and am cutting them to size. Width but not pin count, is listed for the cables so once verified I will update the wiki with the pin counts of each cable as well. I haven’t been able to get the DSI MIPI display to show up yet, it worked for a regular uHDMI output display but
edit:: it seems that after rereading the main kit assembly instructions that the display/hdmi FPC connections aren’t used? So i’m unsure if my webconfig is wrong now but I initially selected the MIPI 800x480.

But the control board is available in the shop:

sorry to be a pain…

do you have a timeframe for restock of kits?

I am keen to get on the zynthian train!

[jofemodo]

We are awaiting the last parts. We hope to have everything in 1-2 weeks.

Thanks both of you- I would prefer to order the remaining pieces of the build versus return the ones I thought were not going to work, so relevant and worthy to ask indeed.

thanks looking forward to ordering
