Sourcing parts for zxuno 4.1 board

Mensaje por mfair13 » 19 Feb 2019, 04:29

I'm not having any luck matching the USB connector. The BOM is pretty generic. Does anyone know the matching part for the USB jack?

I too have been searching for part numbers for many of the connectors, since buying a v4.1 blank PCB.
After finding the Mico-USB connector footprint was a different pitch etc. to one I had that I was going to try to make fit.
And I have been surprised at the lack of details anywhere - both BOM and Schematic lack most of the manufacturer part numbers
- So I'm wondering how the CAD parts models were obtained / built? / what supplier part numbers have been used to build these.
As well as part number for L1-3 0805 Ferrite bead.
I've also noticed that C1 is 4.3pF on BOM, and 7.5pF on schematic, so not sure which is correct!
And for the ZLDO1117 regulators, the more widely availably AMS1117 ones have been fitted in 3D model on User Manual

I've worked out J8 is Molex 53048-0910 & J9 53047-0610 (Although it seems 'micro JST 1.25mm' ones are more widely sold on eBay etc.

So I'd be interested in any part numbers for:
J1 Micro USB, J2 SD/MMC Socket, J3 RCA socket (different to two types I have), J4/5 3.5mm Audio socket.
And also the U5 50MHz 5x7mm (3.3V) oscillator - as well as little detail on load capacitance of the crystals.

For the USB Socket, I've recently found a Molex 0473460001 (Farnell 156-8026 etc) / Tyco 1981568-1 (RS 669-4645 etc.) all-SMT types, that I've now found a few spare of, fitted quite well - Once I'd bent the side tabs down to just go into the PCB's holes.
But it looks like the Molex 1051640001 (Farnell 261-4947 etc.) SMT with thru-hole side-lugs, may fit directly.

And for the RCA / Phono socket, I found Kycon KLPX-0848A-2-Y etc. fitted correctly.
Plus found the 3.5mm sockets were quite common types, seeing these on a scrap LCD-Monitor PCB and also finding some unused ones
(but didn't have any part no. details / marking for these)

However, I'm still looking for details on a suitable SD-Card socket, that fits this v4.1 2016 PCB OK to complete all the connectors.

I have recently discovered a ZX-Uno FB-Group:
- where I've now also asked about this. But I've not had any replies about the SD Card socket.
Although I did have one suggesting USB socket was obtained from an assorted selection of these available on Aliexpress.
