This is Noura from Fusion team. I’m in charge of the OPL service. Gald to E-meet you here. I would like to listen to your suggestions and answer your questions.
Please see the marks below.
I’ve noticed a few ‘quirks’ in the library (and I’m guessing these quirks have been present for a while).
Things like the existence of a tResitrict layer on the 8 pin DIP IC socket which should actually be on the tKeepout layer.
It took me a little while to realise what my ‘issues’ were on the dual row 0.1" headers… The pins are all numbered as if the package was a DIP IC!!!
==Reply==>This is our mistake, we have already revised the eagle library. Please go to wiki to download the newest eagle library.
I’ve made a decent swath of changes to the Seeed-OPL-Connector library to make them more ‘standard’.
If you’re at all interested, I’m MORE than happy to send you my ‘revised’ version of this library?
(I suspect it could be ‘helpful’ to others too?)
==Reply==>Yeah , we will be very gald if you chould send the files to us, I will share this to our layout engineer and learn this. Please share it to my email at firstname.lastname@example.org.
I’ve also largely completed my project BoM. The ONLY components that I could not find in the OPL library are truly trivial! (I’d like to use 39ohm 0402 sized resistors on the high-speed USB pins of the SAM3X8E CPU but the nearest I can find in the library at 0402 size is 49.9 ohm (i.e. I’ve had to specify 301010041 as there’s no 39ohm resistors in the library - let alone in a 0402 size)
==Reply==>We will think about to add one 39Ohm 0402 resistor to OPL. Before we add please check if 301010609 (33R 0402) can work at your board?
Also, there’s a couple of components that are listed in the library, but aren’t (yet?) available to order as part of the PCB Assembly. One was easy to remedy - I simply swapped the BLACK 2*3 headers (320020077) for BLUE ones (320020003).
The second was similarly easy (although not ideal). I had to swap my 500mA PPTC fuse (307010002) with an incorrect 750mA PPTC fuse (307010010), I might as well just install a wire link as it’s not going to do what it should!
==Reply==>It’s our system synchronization problem, we have solved this last week. Sorry for make you inconvenience. Actually you can also place the out of stock components, our purchaser will replenishment the inventory after they saw the order. But customer might don’t know this out of parts can be ordered. We will improve this part this month.
However, I’ve still got an issue on the SOT223 3.3V regulator (310030097 which is a CJT1117-3,3) - Do you have any suggestions?
==Reply==>Please tell me what’s the issue you faced, I will help you on this.
Edit: I just uploaded the BOM again and this time, it’s worked fine… Thanks for fixing it.
==Reply==>We would be glad if you have other suggestions while use this service.
I am still astounded that the comparatively small Seeed OPL libraries defined EVERY single component that I need. Even some of the more esoteric components like ferrite beads! WELL DONE SEEED!
==Reply==> , We are very happy to help you. OPL now is truth very small, we will expand it to more common used components. You can also suggest common used components to us, we will evaluate it and add it to OPL.
