Order PCBs -!!!!!!!!!! TODO !!!!!!!!!! +I ordered my PCBs from JLC, but any PCB service would work. They should accept the exported Gerber zip files in `circuits/Exports` folder. + +I created two circuit boards for this keyboard, one is the multiplexer ([Mux v2.zip](circuits/Mux%20v2.zip)) which uses the CD74HC4067 1:16 multiplexer ic to convert the 61 separate analog inputs requirement into only 5 analog inputs and 4 digital switch outputs. +It also haso diodes and resistors for voltage protection. The other pcb ([OKP-Panel-SMT.zip](circuits/OKP-Panel-SMT.zip)) is for the MIDI control panel containing the buttons and knobs. + +1. Go to jlcpcb.com (Or jlc.com if you read Chinese) +2. Upload the Gerber file +3. Set parameters: FR-4, 2 Layers, Color, leave default for other options + +**PCB Assembly (SMT)** + +If you're not comfortable soldering small SMD components, you can order PCB Assembly from JLC. +You can also select which parts you would like to SMT based on your soldering abilities. +For example, in the Mux pcb, I ordered SMT for only the 0603 Zener diodes and the CD74HC4067 ic, and hand-soldered everything else. + +1. Order "PCB Assembly" (SMT) and click confirm +2. In the SMT menu, upload the BOM and CPL (PickAndPlace) files +3. After uploading, remove the parts you want to manually solder (they're pretty expensive, since someone in the factory still have to manually solder them for you) +4. Order manually-soldered parts somewhere else (e.g. szlcsc.com) ## Usage
