Our smallest DDU, designed to be used with SimHub (Vocore Screen and Audrino programmed for Simhub). Available as a DIY Design (print yourself or with printed parts) or a complete preassembled product.



Our smallest DDU, designed to be used with SimHub (Vocore Screen and Audrino programmed for Simhub).

  • 4.3″ Vocore Screen
  • Single LED Icon
  • 6 Way Directional Switch and encoder
    • 2 Direction Encoder
    • 4 direction D Pad
    • Switch is capable of push button as well with custom code, not enabled in default build.

This combination of features can be used for a variety of purposes: a side screen for relatives, lap timing, changing parameters, track map, gear indicator, or a main center dashboard.

Easy and Cost effective, even for beginners!

Our DIY files include everything you need to perform the build, wiring, and software configuration. Overall this build is very straightforward, total print time is under 6 hours (will depend on your print speed of course) and assembly can be done in under an hour, but no more than a few hours even if this is your first build. Don’t have a printer? No problem, see our available purchase options to include printed parts!

Includes our Rig Mounting System!

Purchasing this design includes our Rig Mounting System for Free! This system bolts right up to the DDU5 and allows you to position the screen at any angle you desire. Mounts are available to attach to 15, 20, 40 aluminum extrusion rigs, and screw on mounts for wooden/other systems.

Purchase options

    • All 3d printed parts shipped to you in your choice of color to match your rig. Parts are printed with ABS filament for strength and finished (depending on selections) for durability.
    • See our page on lead times for printed parts, we occasionally have stock of common colors ready to ship, but most are print to order and therefore do have a lead time to ship.
    • Note: internal non visible parts may be printed in a random color.
  • Complete Pre-Assembled Product
    • For those of you that just want it done and sent! We print and hand assemble and test the product before shipping to you!
    • Includes a set of components from our mounting system to mount to your rig.
    • We include the BOM and assembly guide from the DIY Design package should you need to reference the wiring diagram for reprograming the Arduino or replace any components.
    • Stock and shipping time:
      • Color selections that show “In-Stock” mean we have a complete assembly ready to ship, most will ship next day.
      • “Backorder” means we either need to print parts, waiting on delivery of BOM components, and/or complete assembly. Some BOM components are sourced overseas and have long lead and/or shipping times (sometimes several weeks). This combined with our current print queue could mean delays of a month or more before you receive your product. When you place your order, we will follow up with an estimated ship date.
