serial console uart with leads?

Post by ltgcc »

This is the white 4pin Molex 50-37-5043. It looks like it COULD be a JST style connector EXCEPT for the guiding tabs and slots are on the thin sides.

I know there's a uart kit, but all I need is the connector. I have my own usb converters that I use.

I can find pre-leaded JST connectors (like, say, this one for example:

Code: Select all

https://www.amazon.com/Sets-2-5-4-Connector-200mm-Female/dp/B01DUC1S14/ref=sr_1_3?crid=2RXT189WD8IUN&keywords=2.54mm+4+pin+jst&qid=1655860090&s=electronics&sprefix=2.54mm+4pin+jst%2Celectronics%2C167&sr=1-3
.
but no pre-leaded Molex 50-37-5043.

Does anyone know where and/or what part number pre-leaded Molex 50-37-5043 can be ordered from? I could even go for a lot of 10 or 12, as long as the shipping to USA AK/HI was not a king's ransom.

<grrrrr. why do manufacturers continue to insist on doing inconsiderate garbage like this? A 4pin header or a 2.54 or even 1.25 JST would be so much more easy for everybody.>
</rant off>

Thanks in advance

We've used the 4pin 2.50mm Molex connectors since '2008 and already shipped near 30,000 USB-UART kits.
If we change the connectors, there will be a tons of e-waste again.

Anyway, you can use a generic jumper wire (DuPont cable) temporarily something like the following pictures because 2.54mm pitch is not quite different from 2.50mm.

I agree with odroid. You can use generic dupont connectors. To make it fit better, remove the black case from RX or TX.

thank you for the very prompt reply.

I am currently using the dupont style connectors, but with all respect the craftsman in me can't help but see that as a cheesy solution. But it does work I guess. In other times I'd probably think about removing the molex and replacing it with a JST or a header. I don't have that kind of eyesight or patience anymore though.

While I understand the argument about e-waste and the (more relevant) argument of wanting to maintain consistency, in this instance I stick by my original argument and would urge odroid (and not just odroid 8) ) to phase out parts that are more esoteric and difficult to work with for hobbyists, students and one-off shops in favor of plentiful, easily obtainable, cheap and probably hobbyists and students and such are more likely to have laying around.

Again, thank you for the reply.

With kind regards

There is an alternate solution. You can recompile uboot and switch to the alternate console on the 40 pin connector. You can change the kernel console parameter to the alternate serial port.
But it requires tinkering on your end.
