    CubuSynth Engine - Build Guide PCB V1.1 Jul 2022 Introduction This Build Guide is written for buiders with experience in soldering and assembling PCBs. Due to the complexity of the build, the guide is focused on the steps that require special care or techniques.
  • Page 3 CubuSynth Engine - Build Guide PCB V1.1 Jul 2022 BUILD GUIDE STEP 1 (Main PCB) Diodes 1N4148 D8,D9 Identify the 1N4148 diodes and put them in place. Orientation is Important! Make sure the line on the diodes lines up with the stripe on the PCB silkscreen.
  • Page 4 CubuSynth Engine - Build Guide PCB V1.1 Jul 2022 STEP 3 (Main PCB) ceramic capacitors C28,C29,C30 100n C12,C14,C16,C19,C25,C31 1nf is marked as "102" 100nf is marked as "104" Orientation doesn't matter. Put them in place and bend the solder legs outwards, so they don't fall when turning around the board.
  • Page 5 CubuSynth Engine - Build Guide PCB V1.1 Jul 2022 STEP 4 (Main PCB) Power header HDR-M-2.54_2X5 Turn around the board and place the Pin Header like shown below. Put some tape, to hold them in place while soldering from the other side.
  • Page 6 CubuSynth Engine - Build Guide PCB V1.1 Jul 2022 STEP 5 (Main PCB) Transistor Take the 2N3904, put it in place and make sure the orientation is correct. The outline of the transistor has to match with the silkscreen on the PCB. You can bend the 2 outer legs of each transistor, so it doesn't fall out when turning around the board.
  • Page 7 CubuSynth Engine - Build Guide PCB V1.1 Jul 2022 STEP 7 (Main PCB) Toggle Switch Pin headers Place the toggle switch in the correct spot. Take the 8-Pin Headers (Male) and Sockets (Female) and stick them together. Place them on the Main PCB, with the female header down, but don't solder yet! Below you can see the correct placement of the switch and the pin headers.
  • Page 8 CubuSynth Engine - Build Guide PCB V1.1 Jul 2022 STEP 8 Control PCB Now take the other PCB and fit it on top, so the shaft of the switch goes in the big hole and all pins of the male headers are showing through their solder pads. Fit the nuts to the switch and carefully turn the board around.
  • Page 9 CubuSynth Engine - Build Guide PCB V1.1 Jul 2022 STEP 10 (Control PCB) LED-TH-3mm_W LED13 For the LED the orientation is important! The longer leg goes in the upper hole, while the flat side of the LED points down. Solder it flush to the PCB.
  • Page 10 CubuSynth Engine - Build Guide PCB V1.1 Jul 2022 When everything is in place, put the front panel on top, so all controls go into each corresponding hole of the panel. Make sure everything fits well. Fit all nuts to the Potentiometers and Jacks.
  • Page 11 To connect the module, plug in the 10pin Ribbon cable correctly to your CubuSynth Engine and the Exhaust while your rack is powered OFF! Make sure orientation is correct. (Red stripe down). Then turn on your case, and Page 11...
