Thanks to tehn and unsped’s great work, which help more and more people have their own Monome device now.
Months ago, we sourced the first monome like all-in-one buttons for people who prefer cheaper monome DIY or Non-silicone alternatives.  It’s good to start with a tiny 4*4 or even 8*8 one on proto board,  but if you want to make it 16*16, it’s going to be a bit headache. So we provide PCB chasis PADs to leverage the construction work.
This is the second version, fully compatible with Arduinome Shield or Monome 40h kit. Improvements to the older red one are:
  1. 8*8 array ( we realized that very few people use 4*4…)
  2. Separate wires for buttons and leds. We shared the wires in last version, which proven a trouble to most people who are linking it with 40h logic board.
  3. Absolutely black PCB.

Tips for assembly:

We worked our demo base on Arduinome Shield,  it’s the easy an fun part, you may refer to my steps as below:

1. Solder the LED-Buttons onto the pad.

The All-in-one LED Button has a “+” on its bottom, which matches the square pad of LED Button PAD. Insert them carefully, make sure they are closely attached to the PCB, then solder.

2. Solder the Diodes.

The arrow points to the black belt end of LS4148. It’s easy even for newbie, just place some solder on one side first, then use a tweezer to place the diode and solder it to a well matched position… Finish one end for all, and fix the other end all together. It will just take a few minutes.

3. Solder the 1*8 pins onto the LED+1, LED-1, SW+1, SW-1 ports (at least)

4. Assemble Arduinome

5. Connect every player

Arduinome Shield: SV8-> 64 LED Button Pad: LED+1

Arduinome Shield: SV5->64 LED Button Pad: LED-1

Arduinome Shield: SV7->64 LED Button Pad: SW+1

Arduinome Shield: SV4->64 LED Button Pad: SW-1

Mount Arduinome Shield on ….duino you are using.

and …ACTION~!

Note: propaganda PCB service is for open source PCBs, but we are not going to sell Arduinome or 40h logic board individually according to the non-commercial license. Hope our work will help more people enjoy the wonderful monome idea, we will answer any technical question in our forum.
