JLCPCB production

All nececery files to manufacture this board in JLCPCB available in this Git. Some part are missing in JLCPCB file, because not available in JLCPCB catalogue. Part's number/value U can find on schematic. Mosfet's, MAX9926 available in Mouser. Correct part placement in part_placement.png file. Cypress chip is nececery if U want use Wideband controller.

scg-ecu-2.0-stm32f407-8x8's Issues

JLCPCB Component Assembly

Hello Krzysztof,

I was trying to build this assembly in JLCPCB, and there were a couple of errors I noticed. The first was that there are a couple of designators defined in the CPL that weren't found in the BOM. Those designators were:

Q1, Q2, Q3, Q4, Q5, Q7, IC7, U$10, L2, L4

The second issue I came accross was the placement of many parts in the CPL file. All of the parts were offset from the board, and the rotation of many parts was off. Some of this is easy to fix, but other polar components without markings on the board are a bit harder to orient.

Thanks for all you're hard work!
