5. Order from JLCPCB

You can of course use the project files to order from any PCB manufatorer, but I'm only going to write a guide for JLCPCB, since I've build this circuit with their component library in mind.

1. Go to JLCPCB.com and upload your Gerber folder

It is gonna take a bit of time, just wait for the full upload.

2. Change the following settings

• Layers: 4

• Impedance control: Yes

• Layer stackup: JLC04161H-7628

• Remove order number: Specify a location

Epoxy via covering is selected in this picture, this is not need. Tented will do.

Other settings left to default (as shown in the image above).

You can change Surface Finish to LeadFree HASL or ENIG, but changing color of the board will come with a big cost increase because it is not available as PCBA type Economic.

3. Check PCB Assembly

• Make sure you've got Economic PCBA type checked, it is way cheaper than Standard. If you cant select it you did something wrong in step 1.

• You can set the PCBA Qty to 2, which is the lowest number of PCBs to get assembled.

• Select Confirm Parts Placement, as it is free.

4. Finalize

• Next steps is just clicking next and next, uploading the BOM and Pick&Place file (CPL).

• You will get an error on the component "IO", which is just a layout for all the connections used in the schematic, it is not a real component. Go ahead with "Do not place".

• Save to cart and order!
