PCB Production
11/18/2019 at 14:39 • 0 commentsJLCPCB has started the production of the PCBs. They passed the initial approval process. I'm not sure if that process is automated or not. According to the DFM analysis, it looks like I had my whole board rotated. Not just footprints being rotated, but the entire board?
The DFM analysis noted the following error "Cannot find this Pad in your PCB" for U1 and U6. I'm guessing this means that it could not determine pin 1, but in both cases the parts are correctly placed. Some parts that are on the assembly list don't show up in this rendering namely the switches and the common mode filter. I've emailed to find out the details on that.

- PCB's ordered
PCB's were ordered today. Should be around a week or so. This is my first live experience with JLC's SMT service. I've put together a couple test boards that I never had sent off, so I will see how this goes. There are a couple components that JLC does not have for the board. Most of them I have on hand, but a few I will have to order and solder on when I get the PCB's
I need now, to switch focus and get the LoRaMac-node firmware running on these. I've gotten it running on NucleoL073 with SX1262 MBed shield, so this shouldn't be a tough putt. Once that is done, I'll include a link to a build-able project that should get anyone started with a LoRaWAN Feather!
