Hello,

i send your gerber file to jlcpcb and i become it. If i start the placement i see that i miss J1 in your kicad and C17 for 100nF 100V i stop the placement. Can you help me or say if the J1 there or what version i have? Best Regards Michael

Hi,

the hardware was still a bit of a work-in-progress, so there was a disparity between schematic and Gerber. I added the first working hardware rev (the Gerber you are referring to) to hardware/V1. Please note that post-production you need to add a 10k 10turn trimmer to the hardware V1 with the current software:

       10k 10 turn
Vcc ---- [    ] ---* GND
           ^       |
           |       |
           * --||--|       100nF
           |
          AIN3

This mod is already included in hardware/V2.

Best regards,

Patrick
