Tubbutec Sumtiple Kit Version – Construction Manual

This  document describes the construction of the Sumtiple Kit. The following parts are 
included:

1x Sumtiple PCB with SMD-Parts already soldered

1x Front panel

8x Jack sockets and nuts

1x RGB-LED

1x 10-Pin Header

1x Power supply cable

Tools needed to build Sumtiple:

Soldering iron, solder

Side cutter

Pliers

Multimeter for calibration

Small screwdriver

Construction

First you should start with preparing the parts needed for proper construction. Check the 
pictures for a better understanding of what needs to be done.

First take the jack sockets, you need to pinch off a little of each pin. The pins need to be  
cut to a length of 1mm. If they are not short enough, they will stick out of the board and 

may touch a module next to it.

 

The sockets should look like the one left in the pictures above. When you have prepared all 

8 sockets, take the PCB and put the sockets on it like shown.
