Tarrelis D-35 · the first model · 3.5″ · Motorsport
Built to race.
A 3.5″ high-brightness race dash, 1100 nits. It plugs into your car's CAN bus and shows only what you need on track. Limited pre-order · first deliveries March–April 2027.
Four layers. No compromises.
Every part is designed for a race car, not a desk.
On track, you see everything.
RPM, gear, speed, temperature, oil pressure and battery. Seven shift lights that need no explanation.
Features
Readable at 200 km/h.
No generic screens. Brightness for the track, inputs for your sensors and a design that doesn't distract.
High brightness, readable in full sun
More than three times the brightness of generic 300-nit screens. Readable with the sun coming through the windscreen.
Shift lights
Seven addressable LEDs above the screen, with colour and RPM configurable per gear.
Just the right size
A 3.5″ rectangular panel. Big enough to read at a glance, small enough not to block the wheel or the dashboard.
OBD2
Reads data straight from the car's CAN bus or the ECU. Any vehicle from 2008 on, plus our own profiles for several older cars and the usual motorsport ECUs.
Extra inputs
Up to six 0–5 V analogue inputs for external sensors (pressure, temperature…): whatever you don't get over CAN goes straight into the dash, and they also take ground-switched buttons for page change or alarms. Plus two digital inputs for speed and RPM, for cars without CAN bus or to add signals.
Auto brightness
Built-in light sensor: full brightness by day, comfortable in night races. And no touchscreen, on purpose: better contrast and zero fingerprints.
Installation
Power and CAN bus. Nothing else.
On cars from 2008 on, one cable straight into the OBD port and the dash is reading the car. No wiring changes, no extra sensors.

Configurator
Set it up from your phone. No app.
Connect your phone or laptop to the dash and adjust everything from the browser: what each page shows, shift lights, alarms, calculated gear and day/night brightness. As many pages as you want, switched with the button. Saved to the dash in one click.
4:3 screen · every value in its own colour · the on-screen light bar can be removed: the seven physical LEDs sit right above it.
Electronics
Designed from scratch. Ours.
It's not a dev board in a box. It's our own electronics, with the CAN bus, power supply and inputs a race car needs.
Reads the CAN bus and redraws the screen without stutter, even on the limiter.
Power and CAN bus in one automotive connector with a side exit, for a clean install.
Per-car setup: scales, alarms and pages stored on the dash itself.
One button. No touch menus, no looking away longer than you need to.
Team
Who's behind it.
Tarrelis is a team led by René González and a group of companies that make manufacturing possible. We design the electronics and firmware, and the board, housing and wiring are made in Spain, each part by a specialist company.
Our own electronics, no dev boards. CAN profiles developed car by car.
Boards, housings and harnesses made in Spain by the group's partner companies.

FAQ
What people ask us.
Which cars does it work with?
Any car from 2008 on, over CAN bus (OBD2), and programmable ECUs such as Ecumaster, DTA, MoTeC or MaxxECU. For older cars we have profiles for the Clio Sport 2 and 3, Audi A4 B5, Ford 2003–2006 and Opel Corsa C. If yours is different, tell us in the form.
How is it installed?
Power and CAN bus. On cars from 2008 on, with one cable straight into the OBD port, without touching the car's wiring. The housing mounts wherever you want to see it.
When does it arrive?
The first units ship between March and April 2027. They go out in order of reservation and we email you when yours leaves.
Can I customise it?
Yes. The pre-order includes customisation: a boot screen with your logo and setup for your car. Pages and alarms you change yourself in the configurator.
What if I change cars?
The dash stores several vehicle profiles. Switch profile and you're done.
Will there be more models?
Yes. The D-35 is Tarrelis's first model, the 3.5″ one. The next one, a 5″, is already in development, with more motorsport products to follow. More about the Tarrelis D-50.
