Hi Niklas,
which exact USB-receptacle do you use? These look promissing: https://lcsc.com/product-detail/USB-Connectors_Jing-Extension-of-the-Electronic-Co-Jing-Extension-of-the-Electronic-Co-USB-3-1-C-16PF-SMT2-0Type_C167321.html
Do you have any left over, that you could bring to 36C3? Cheers Jan
Hi Jan.
That BOM you linked to at digikey above, is it complete? did it work?
BTW, what lcsc components are you referring to?
Yes, it worked.
If I remember correctly: The C-1206 arround the mosfets should be 50V instead. (C39,42 - C34,C41 - C16...) The USB-connector is from LSCS - see link above. Cave: The Silkscreen for R5 and R11 is interchanged. You do not really need the SW1 - it is only pressed once for programming.
Have fun!
Thanks Jan, that;s good to know. BTW which of the inductor options did you use for L1-L3?
I also found this USB connector on Digikey: https://www.digikey.com/product-detail/en/gct/USB4105-GF-A/2073-USB4105-GF-ACT-ND/11198510
It looks identical to https://lcsc.com/product-detail/USB-Connectors_XKB-Enterprise-U262-16XN-4BVC11_C319148.html
What is the voltage rating of C17-19? It's not stated on the schematic or iBOM.
e.g.
I know this isn't directly related to the BOM, but I wonder if you can answer it: Am I supposed to be able to see the discharge even if I am not playing any music?
I ordered the parts on digikey and tried to replace the LCSC-Components. http://www.digikey.de/short/p1dcp2
I was not able to find a replacement for L1 - L3 Do you think this might work although it is only rated for 1.15A instead of 3A? I never worked with Inductrs before and have no idea what to look for. https://www.digikey.de/product-detail/en/MLZ2012N1R0LT000/445-6756-1-ND/2523577/?itemSeq=312817283
As an alternative I ordered these. They have only 55mOhm but 3.3A. https://www.digikey.de/product-detail/en/CIGT201208EH1R0MNE/1276-6886-1-ND/7041286/?itemSeq=312817286
I'm an getting exited! :) Hope to see you in Leipzig.
