Trinity Assembly




Hey dudes! Lets build the trinity synt!

Trinity Assembly




Before you start: the board solders from both sides and the component goes always above its printed sign so it hides the sign!

You should know that there are some differences between some of the versions.

SQNCR has more buttons and 3 small leds insteas of the rgb led and therefore different resistors too.
Mozzi library development kit has no casing and the small buttons are not tall.
This instructable is for trinity board version 1.0

Step 1: Placing Resistors

Placing Resistors

First lets solder all components on the component side of the pcb.
Different slots for resistors have different values of resistors. Read the color stripes or measure the values with multimeter.
-4x 220R – red red brown ( on board 1.1 three of these 220r are labeled zOhm)
-1x 4.9k – yellow white white brown (4.7k also works yellow violet red)
-1x 39R – orange white black
!!!
-3x xOhm are 1k brown black red !read the board carefully!
-3x yOhm are 15k brown green orange BUT on SQNCR they are 1k brown black red !

Step 2: Place the protective diode

Care of the polarity indicated by the stripe

Step 3: Solder

Bend the legs or the components slightly and turn the board upside down and solder each connection properly. Than cut the legs.

Step 4: Chain Connectors

Take these an solder now. Tip: it is always good to solder the least tall parts first.

Step 5: Atmega Socket and Audio Jack

On the chip socket mind the polarity indicated by the notch. On the audio connector try to solder it the way that there is NO gap between the connector and the pcb. Than cu the remaining legs of the jack. Double check that you solder from the correct side of the pcb!

Step 6: Bend The Switch

Carrefully bend the legs ! ONE BY ONE ! of the slide switch into right angle. It does not matter to which side you bend them, but by not gentle bending you might damage the switch.
