Analog Discovery 1 micro usb replacement

[kaktusak]

I've got a problem with using my AD1 board, WaveForms is not detecting it anymore and it seems to be a usual problem with micro usb connector. I've checked continuity between connector pins on the pcb and the usb cable end and there is no connection between black/red wires and sides pins, only green/white seems to be connected to middle pins. Hence next I will try to replace micro usb connector but I couldn't find the same as used on the board. Can anyone have BOM/ part number for the connector?Or can I use any connector like molex (part number 47590-0001)?

thanks

Hi @kaktusak

This is the USB connector of Analog Discovery 1: http://www.wisconn.com.tw/Products-detail-en.aspx?P_Id=1519

and here you have the layout:

Thanks!, that's the info I needed, now I just have to find this connector (or similar) somewhere

Link is to 180deg connector which is wrong, I've checked the connector and it's actually different, it has two mounting holes to the front, no mounting pads and has the horizontal orientation, type AB. Wisconn doesn't have the same on the offer?, most close are WMRU2-05FLBDSR-4.0 and WMRU2-05FLBDSR but they are type B.

The most similar seems to be TE connectivity 2134536-2

Also my board (rev c, PB200-244 as written on the top) doesn't have on the top layer those traces between D+ and D- (middle) USB pins and FTDI IC, maybe it's different revision?

Hi @kaktusak

You are right, the exact part is: WMRU2AB-05FLB2DSR-4.0
I can't find this part on the net, but here you have the specs for it: MICRO USB AB TYPE SHELL DIP(WMRU2AB-05FLB2DSR-4.pdf
