This new version should be easier to order.
Look at the Wiki for a lot of usefull informations
It should not trow errors while uploading BOM and CPL files at JLCPCB, all components should be available most of the time.
Changes for V4.5:
Changed many parts for cheaper/more available ones
Added schottky diodes on WAS inputs for better protection
Changed pressure sensor input for better protection
Added jumpers to the speed pulse circuit to be able to pull-up to 5 or 12V and to connect the (-) side to GND directly on the board
Modified Teensy power circuit to be able to load firmware without 12V or without removing it from the board. (Cutting the 5V trace on the Teensy is still mandatory if you want plug the Teensy USB in the board powered) More info here
Lock traces have been increased: Continuous current capability: 4 amp on micro, 5 amp on STD. But you must put a bigger diode than the 3 amp SMD on board.
For the STD only:
Changed/Repaired the BINAV footprint to use UM982 by default. BINAV can still be used.
Once you have your board test it, instructions here:
It is possible to pre-order parts at JLCPCB to your own “private” parts inventory. Sometimes the min is a bit high but on the cheap parts it’s still not a significant amount. Then when you order PCBs, they will use from your “private” inventory.
Which size of board are you trying? I just tested the Micro & Standard, both work. I suspect you’re uploading the main zip file which has more then just the Gerbers. Either extract the three JLCPCB production files and upload those accordingly or just download the three production files individually. You start with the Gerber.zip, then later the BOM & CPL.
