Custom Arduino Hardware
Not able to put together an Arduino of your own to run the sketches on this page? No problemo!
We now have available a limited supply of custom built hardware, based on an Arduino Pro Micro, with CANBUS shield and dedicated K-Line interface included.
These come complete with a case, which is small enough to fit just about anywhere, pre-installed sketch configured to your requirements, and a labelled wiring harness.
All you need to do is code your RNSE for OPS, and wire it up!

Please contact us to check availability and arrange a purchase.
Cost: £45 (GBP) + postage:
- UK - £5
- EU/NA - £10
- ROW - Contact us for postage costs
Our latest firmware for these modules now also supports:
- Ability to adjust volume and frequency from the RNSE OPS menu.
- OPS on A4 (8EC/8ED) with 8E0 919 283 B PDC module.
- Enabling of TV/AV input on RNSE via CANBUS (Separate hardware required for CVBS to RGB conversion).
Please contact us if you wish to upgrade your existing unit.
Known compatible PDC modules:
- 8Z0 919 283 A via KWP1281 diagnostics for Audi A2 (8Z) / Audi A4 (8E2/8E5) / Audi A6 (4B)
- 8E0 919 283 and 8E0 919 283 A via KWP1281 diagnostics for Audi A4 (8E2/8E5) / Audi A6 (4B)
- 8E0 919 283 B/E via KWP2000 diagnostics for Audi A4 (8EC/8ED)
Your PDC module must match one of the above part numbers exactly, including the letter suffix to be compatible.
As and additional check, when you connect with VDS, the protocol KWP1281 or KWP2000 should display in the top left of the window.
If you have some other part number which uses KWP diagnostics (CAN is not supported), then you should contact us for advice.
