  • Page 1 Assembly Guide...
  • Page 2: Assembly Guide

    Assembly Guide These assembly instructions will help you build your Robaux 3PT. All necessary components are included in this kit. You will need the following tools: soldering iron, wire cutter and solder. Also a desoldering pump and a screwdriver. Read the instructions carefully and follow the steps in the correct...
  • Page 3 LEDs Let‘s start with the LEDs. Solder the 42 LEDs as shown in the picture. Please pay attention to the polarity of the LEDs. The long leg goes into the + hole, the short leg goes into the - hole. Diodes Now solder the eleven diodes to the board as shown in the...
  • Page 4 Resistor 1K Now solder the 1K resistor to the board. You can recognize the resistor by its color code brown, black, red, gold. Trimmers Now insert the nine trimmer as shown in the picture. Please do not solder the trimmers yet!
  • Page 5 Potentiometer Now insert the potentiometer as shown in the picture. Please do not solder the potentiometer yet! Thonkiconns Now grab the four Thonkiconn Jacks and place them in the PCB. Please do not solder the jacks yet!
  • Page 6: Tact Switch

    Tact Switch Now plug in the tact switch. Please do not solder the switch yet! Ring Now take the ring and put it between the LEDs as shown in the picture.
  • Page 7 Panel Now place the front panel care- fully on the board. Hex Nut Fix the potentiometer with the nut.
  • Page 8 Knurled Nuts Use the knurled nuts to tighten the jacks on the front panel. When everything is screwed tight and all components are aligned, you can solder the sockets, the trimmers and the potentiometer. Header 7 Unscrew the nuts and remove the front panel.
  • Page 9 Knob Now put the front panel back on, screw on the potentiometer and the sockets. Finally, put the knob on the potentiometer. Resistor 12K Take the second PCB. Now solder the three 12K resistors to the board. You can recognize the resistors by their color code brown, red, orange, gold.
  • Page 10 Resistor 47K Now solder the three 47K resistors to the board. You can recognize the resistors by their color code yellow, violet, orange, gold. Resistor 10K Now solder the four 10K resistors to the board. You can recognize the resistors by their color code brown, black, orange, gold.
  • Page 11 Resistor 1K Now solder the six 1K resistors to the board. You can recognize the resistors by their color code brown, black, red, gold. Resistor 100 Now solder the seven 100 resistors to the board. You can recognize the resistors by their color code brown, black, brown, gold.
  • Page 12 Diodes Now solder the three diodes to the board as shown in the picture. Please pay attention to the polarity! Crystal Now solder the 16MHz crystal as shown in the picture.
  • Page 13 Capacitor 104 Now solder the 104 capacitor to the board as shown in the picture. Capacitor 220 Now solder the two 220 capa- citors to the board as shown in the picture.
  • Page 14 Rectifier Now it‘s time for the rectifer. Solder this to the PCB as shown in the picture. Note that the - and + symbols on the board match the symbols on the rectifer. IC Socket 28 Now solder the IC sockets to the board.
  • Page 15: Power Socket

    Capacitors Now solder the two Electrolytic Capacitors to the board as shown in the picture. Please pay attention to the polarity of the Capacitors. The red mark must match the mark on the PCB. Power Socket Solder the socket as shown in the picture.
  • Page 16 Pins 4 Place and solder the Male Pin Headers as shown in the pictu- re. It is the shorter pins of the pin header that you are soldering. Step Down Now solder the step-down adapter as shown in the picture.
  • Page 17 Pins 7 Now solder the three pin strips. Tip: temporarily plug this onto the other PCB so that everyt- hing is properly aligned. Trimmer 104 If you want you can now clean the back of this PCB. Then solder the three trimmers to the back as shown in the picture.
  • Page 18 DACs Flip the board over again and insert the two DACs side by side as shown in the photo. Make sure the nose is facing OP Amp Now insert the amp. Make sure the nose is facing up.
  • Page 19 ATMega Now insert the ATmega into the socket. Be sure the nose is facing up as shown in the picture. Voilà! Now put the two boards together and your module is ready! Please note the instruc- tions for calibrating the module in the user manual.
