02. BUILD
20. Solder the 2x3 and 2x5 pin right angle headers
(Make sure they are nice and parallel to the board)
You are done with the main board!
21. Orient the PCB like this
22. Solder the single 360R resistor
(This is for the jack LEDs, this is optional and it’s value
can be changed depending on the LEDs you are using)
23. Solder the 12x 470R resistors

02. BUILD
28. Turn the PCB around
DO NOT SOLDER YET!
29. Place the 12xLEDs
(Check their orientation, long leg goes into +)
30. Place the button and it’s cap
31. Place the two jacks
28 29 30 31

02. BUILD
32. Screw in the spacer from the bottom side
33. Now place the front panel on top, put the nuts on the
jacks, align everything nicely, and screw in a screw
from the front in the spacer as well. If you like how
it looks, solder everything on the other side!
34. Now place the row of right angle header between the
two boards as shown in the picture (top view).
Make sure that the boards are perpendicular to
eachother, then solder on both boards. It helps to
solder just one pin on each board first, adjust them,
then solder the rest.
You are done with building! Congratulations!

03. UPLOADING SOFTWARE
1. Download the firmware from the Antumbra website.
2. Connect your AVR ISP device to the 6 pin ISP header
on the module. Pin 1 is marked with a dot.
3. Use an AVR programmer, like AVR ISP MKII with for
example AVRDUDESS to upload the code.
Fuse settings should be set to:
L-fuse: 0xff • H-fuse: 0xde • E-fuse: 0x05
4. After you’ve uploaded the firmware with bootloader,
connect the module to your power supply. If you were
successful, you should see the welcome animation.
