Summary of Contents for Robaux SWT 16

  • Page 3 Also a desoldering pump and a nut driver. Read the instructions carefully and follow the steps in the cor- rect order. Robaux wishes you much fun building the Sweet 16 Sequencer. LEDs We start with the button board.
  • Page 4 20 Pin Header Next, solder the two 20-pin headers to the back of the button board. It is best first to solder the two outer pins and then the remaining pins. 4x4 Keypad Now place the 4x4 Button Key- pad on the front of the Button Board.

  • Page 5: Front Panel

    Frame Now put the frame on the keypad. Make sure the holes in the frame match the holes in the keypad. Frontpanel Now it‘s time to put the front pa- nel on the buttons. Make sure that the small arrow on the back side of the PCBs is pointing to the top left.
  • Page 6 Screws Now fix the front panel, the frame, the keypad and the but- ton board with the two screws. Insert the screws through all parts as shown in the picture. Nuts Secure the screws with the washers and nuts.
  • Page 7 Allen key Tighten the screws with the supplied Allen key. Please do not over tighten the screws so that none of the parts will be damaged. Resistor 220 Now pick up the motherboard and solder the nineteen 220 ohm resistors as shown in the picture.
  • Page 8 Resistor 10K Now solder the three 10K resistors to the board. You can recognize the resistors by their color code Brown, Black, Orange, Gold. Diodes Now solder the sixteen diodes to the board as shown in the picture. Please pay attention to the polarity!
  • Page 9 Crystal Now solder the 16MHz crystal as shown in the picture. Array 10K There are even more 10K resis- tors in the form of two resistor arrays. Solder the two arrays as shown in the picture. Please note that the arrays soldered in the right direction: the GND must point upwards.
  • Page 10 Array 1K There are even more resistor arrays. Solder the eight 1K resistors to the circuit board as shown in the picture. These arrays do not have a specific direction to follow. Capacitor 220 Now solder the two 220 capa- citors to the board as shown in the picture.
  • Page 11 Capacitor 104 Now solder the two 104 capa- citors to the board as shown in the picture. Rectifier Now it‘s time for the rectifier. Solder this to the PCB as shown in the picture. Note that the - and + symbols on the board match the symbols on the rectifier.
  • Page 12 IC Sockets Now solder the seven IC so- ckets to the board. It is easiest to solder first only the outer pins and then the remaining ones. 4 Pin Headers Place and solder the both Male Pin Headers as shown in the picture.

  • Page 13: Power Socket

    Step Down Now solder the step-down ad- apter to the pins as shown in the picture. Please note that the names of the pins on the adapter match those on the PCB. Power Socket Now solder the power socket as shown in the picture. Notice that the socket points in the right direction.
  • Page 14 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 white mark must match the mark on the PCB. Button Now flip the Mainboard and plug the button as shown in the picture.
  • Page 15 Jacks ow plug the nineteen jack sockets on the motherboard. If you like, you can trim the pins of the jacks to the same length. Please do not solder them yet! Washer Place a washer on each jack. This ensures that the jacks have the correct distance to the front panel.
  • Page 16 Knurled Nuts Now place the front panel with the buttons on the main board. Align all the jacks and fix them with the knurled nuts. Long Pins Be especially careful because now comes the tricky part! Insert the long pins through the mainboard into the header of the button board.

  • Page 17: Shift Registers

    Trim the pins Now trim the long pins as shown in the picture. Then resolder the pins. Then solder all jacks and the button on the main board. Shift Registers Now insert the Shift Registers into the sockets. Be sure to attach them in the correct direc- tion as shown in the picture.
  • Page 18 Voilà Congratulations! Your module is ready and can be installed in your case. Make sure the pow- er cable is plugged in the right way on both connectors. Enjoy creating beats with the Robaux Sweet 16!
  • Page 19 PCB Adapter Everything is finished - but there is still an unused part? The new version of the Robaux SWT16 uses an ATmega328 chip instead of the Arduino Nano from the previous version. It is still possible to use an Arduino Nano with the included PCB adapter.
