Hi, I was unsuccessful finding a proper VGA cable scheme for dummies (like me :oops:). So I've made one :okidoki;! If you're still in doubt how to connect the ZX-Uno to the VGA monitor, this could help.

Thank you for the diagram. I usually put this one, but it's a little harder to understand. The pin 4 3.3V to VGA pin 9 is not needed.

Dear all, how is the RGB connector in UNO v4.2 officialy called? 9-pin JTAG or different? Thanks much.

It's called microJST 1.25mm 9P

I'm trying to build the RGB to VGA cable.
The connector on the PCB is a male 9 pin right angle, pitch 1.25 mm.

I saw that in the parts list at this link:
https://zxuno.speccy.org/maquina_e.shtml
the RGB connector is branded Molex without a series and part number, but in this forum and at link:
https://zxuno.speccy.org/faq_e.shtml
it is branded JST "micro" series without a part number.

I looked at JST web site:
http://www.jst-mfg.com/product/search_e.php?type=1&id=1
but "Wire to board crimp connectors", with 1.25 mm pitch, there are AGH, GEZ, GH, GHD, GVH series, and to me, no one seems the right one.

Which one is the right PN?
thank you

I looked at Molex web site, and the connector shown in ZX-Uno photos seems this one of PicoBlade series:
https://www.molex.com/molex/products/pa ... 0530480910

I also found:
https://hackaday.com/2017/12/27/jst-is-not-a-connector
that about everywhere this Molex PicoBlade connector is called/confused with "micro JST 1.25 mm", but no one of the connector manufactured by JST is compatible with this one. Molex has flat/rectangle pins like a blade, while JST series has square or round pins.

The female mate for Molex Part Number:530480910 is the PN:510210900
https://www.molex.com/molex/products/pa ... 0510210900
to be paired with socks PicoBlade Crimp Terminal 50058, 50079:
https://www.molex.com/molex/search/part ... uery=50058
https://www.molex.com/molex/search/part ... uery=50079

Anyway apart if you buy from RS, Farnell, Digikey, Mouser or Distrelec, probably you are forced to order a micro JST 1.25 mm connector, and you receive a Molex PicoBlade connector, that is the right one
