Bad placement when uploading to JLCPCB #1
Comments
That happens all the time with the preview at JLCPCB, typically this is corrected during manufacturing data create by them. |
OK, i'll see if I can create a PR to fix. One more question, https://github.com/free-pdk/easy-pdk-programmer-lite-hardware/blob/master/Design%20Files/Readme.md says "The parts listed in Parts to order at LCSC can not be automatically assembled" but this doesn't seem to be the case: they're in the other csvs/Gerber and appear in the design when uploaded to JLCPCB. Was the intention to remove them for hand soldering? I can see "LCSC Assembly" column blank in some rows of the BOM csv, but this doesn't seem to be removing assembly for those components. |
JLCPCB added some parts to their inventory after I ordered the programmer for the last time. I believe now it is possible to have them assemble the USB connector, for example. Impossible to tracke these changes all the time... |
I've just ordered with the usb, will update here when it comes.

I have the parts! I've soldered on the three parts ordered separately from LCSC: the microswitch, the inductor and the oscillator. As you said the USB was able to be fitted by JLCPCB. I have connect this to my windows PC and am trying and failing to flash the firmware using dfu-utils. I get the following :
with the timeout continuing indefinitely, and the Download staying at 0%. No LEDs light at any point. I've tried the various Windows USB drivers as offered by Zadig - no difference. Any suggestions to debug further? thanks |
Tried it on my friends Mac... uploading firmware works!!
so looking for thoughts on issue with Windows (usb?) installing via dfu-util. |
It looks like some kind of stability issue, as the device is correctly indentified and enters DFU mode. Tough to tell what it is. Sometimes there are issues depening on controller or hub. Try different USB ports, try to find ports that are not shared with other devices. |
Update: I managed to order min. quantity 5 of these from JLCPCB for £28, including the USB socket, but excluding the microswitch, crystal and inductor which I got from LCSC and soldered myself. They work for programming an on-circuit PFS154 SO8, but don't calibrate successfully (I didn't realise I needed to expose PA4 pin), so this functionality isn't tested. With other parts, shipping & duty (to post-Brexit UK) I'm willing to sell the extras at cost: £12/$15/€14 plus shipping to your location. |
I tried uploading the Design Files to JLCPCB today and got a layout as shown, assume this needs a fix.
