02. BUILD
DO NOT SOLDER YET!
28. Place the six LEDs
(Check their orientation!)
29. Place the 14x jacks
30. Place the two buttons and their caps
31. Screw in the spacer from the bottom side
32. 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!
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.
