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.
