Disting EX OLED display bracket

I designed and 3D printed this bracket to hold a secondary OLED display for the Disting EX multi-function Eurorack module. No soldering is needed. Photos

This secondary display greatly increases the readability of the Disting EX. It makes the already very powerful Disting EX much easier to use.

This bracket is available in several different versions for different mounting configurations. (see below for details on the different versions.) The simplest version mounts at the bottom to a Eurorack rail. All the different versions are 14HP wide. Note, none of the versions are 1U, and they will not fit in a 1U slot. The bracket does not need or use the PCB adaptor board from Expert Sleepers & Thonk. (Note, the Thonk PCB is 1U-compatible if that's what you need.) 

But this bracket uses the exact same OLED display recommended by Expert Sleepers. You will need to buy this display separately. The display board model is the "Arduino 2.2"128x32 OLED Breakout Board Display Module,Blue on Black" available from BuyDisplay.com. Choose the "Pin Header Connection-4 Wire SPI" option. The link is to the blue OLED version, but other colors are available. When this is published the display board is $15.

You will also need 7 Dupont socket-to-socket cables (20 cm length) (aka female-to-female). These are available wherever DIY small electronics parts are sold.

The bracket holds the OLED display to which you directly connect the 7 Dupont socket cables. The cables thread through a slot on the back. Sockets at the other ends of these Dupont cables connect to the two jacks on the back of the Disting EX (just as with the PCB). Refer to the Expert Sleepers Github page for details on the connections: Expert Sleepers Github page.

Wiring summary:

• display pin 1 - Disting GND
• display pin 2 - Disting VDD
• display pin 4 - Disting D/C
• display pin 7 - Disting SCLK
• display pin 8 - Disting SDIN
• display pin 15 - Disting CS
• display pin 16 - Disting RESET

Pay attention that display pin 1 (GND) is on the left when viewed from the display front and on the right when viewed from the back where you will plug the Dupont cables to the pins.

Note: there are now 5 variations of the display holder: rail above, rail below, either rail above or below (not both) or embedded in a full 3U 14HP panel. You only need to print one version plus one cable guide.

The two 3D printed parts require assembly with tiny screws -- 4 screws to hold the OLED display PCB to the bracket, and two screws to hold the cable routing slot on the back. Since it is 3D printed you should pre-tap the plastic holes for the screws with a tiny drill bit to match the tiny screws. I used #1- 1/4" wood screws.

You are free to download and print this for non-commercial use.

Use this at your own risk, of course.

Notes:

There are several different versions of the display holder. You only need to print one version: choose which configuration you need.

• displayHolder_railBottom.stl - Display PCB holder with Eurorack Rail mounting holes at the bottom;
• displayHolder_railTop.stl - Display PCB holder with Eurorack Rail mounting holes at the top;
• displayHolder_railTopOrBottom.stl - Display PCB holder for mounting to a Eurorack Rail at the top OR the bottom (note: it doesn't mount to two rails! See full panel versions below);
• displayHolder_lowIn3UPanel.stl - Display PCB holder low in a full 3U panel (the panel is 2mm thick);
• displayHolder_highIn3UPanel.stl - Display PCB holder high in a full 3U panel (the panel is 2mm thick);

Additionally you will need to print one

• cableGuide.stl

Additional BOM:

• 6 tiny screws.

e.g. #1 x 1/4" wood screws.

• 7 socket-to-socket Dupont cables

Example

• 1 OLED display and integrated PCB unit

BuyDisplay.com; choose the "Pin Header Connection-4 Wire SPI" option.

Other colors are available.
