Hello Axiris, Thank you for your quick responce. I am looking forward to the next firmware release I want to say that it is a nice clock to build. I enjoyed it. But I have one disadvance about the PCB design. I don't like that both side of the PCB has a ground plane. It was difficult to replace T9 because all the heat from my solder iron was disappeared into the ground plane. I don't know if someone else has a solution for this problem. This was the only drawback I can find so far. Nick

Hello,   for a quick manufacturing, I chose http://www.allpcb.com currently, it's around $ 20 for 10 PCBs (arduino format) delivered in 7 days, or $ 15 for 10 PCB 50x50mm The follow-up of the production is very detailed In december 2017, I paid $5 for 10 PCBs delivered in 7 dayshttps://twitter.com/laurent_le_goff/status/946137177641111554 for my arduino 1284 (https://github.com/llegoff/bobuino)

Because that sounds like a plausible explanation, I searched my computer and found libusb0.dll in 24 places on the C drive and 36 places on the D drive... Too many to clean up so I took another Windows 10 PC and deleted all instances of libusb0.dll and with that everything remotely related to Arduino. I then scanned the PC again to make sure that libusb0.dll was really gone. I downloaded the Arduino IDE 1.8.5 ZIP file, installed it and rebooted the computer. Rescanning it for libusb0.dll resulted in four instances all located in the fresh Arduino installation. I installed the Uno R4 Boards package from GitHub through the Boards Manager, connected the Uno R4 and loaded the BlinkWithoutDelay example. It compiled without errors and then uploaded to the board without errors. Deleting once again all (4) instances of libusb0.dll now finally resulted in an upload error, but it went away after placing the DLL back to the folder where arduino.exe lives. To me this seems to indicate that it is not necessary to have a libusb0.dll in the avrdude folder.

https://oshpark.com/ they charge you for the space you use, so if your PCB is really, really tiny is a good option, if it is more than 2 square inch it might get a little expensive. i have used their service in my robotics projects and college projects. Although their quality is great, they have issues too, so far i had received one order faulty (all PCB had small dots of copper where it shouldn't), and one half faulty order (just half of the order had the same problem of copper dots). if you send them an email, alongside some evidence of your claim, they resend your order to the fab for free (that's cool). the shipping is free, but not always reliable, at least for mexico, so that something that's on my side
