Your car

ECU & CAN bus

Which ECU this car has, what speed the bus runs at, and whether frames are arriving.

–

OBD2 diagnostics

Trouble codes, VIN and ECU name, protocol status. Adding OBD2 readings as channels lives in Channels.

–

Gear calculation

Work out which gear you're in from RPM and speed, when the ECU doesn't send it.

Configurable

Fuel sender

Teach the dash what your tank reads when it's empty and when it's full.

Calibrate

Odometer

Total distance, counted from the speed signal. Set it to match the car.

–

Keypads & IO boxesIn development

Buttons on the screen that your ECU reads as its own keypad or IO box — cruise control on a Haltech, for one.

—

This dash

Screen & night

How bright the screen is, and what makes it dim at night.

–

Layout switching

Pick which dashboards the arrows on the dash cycle through, and in what order.

Configurable

Device & updates

Serial number, storage and live health. When an update is out, a banner at the top offers to install it.

–

WiFi & network

Which network the dash is on, its address, and how to reach this editor.

–

Data

Live data & recording

Watch every reading arrive: value, min/max, whether it's gone stale. Press Record to save it to a file, either on the SD card or the dash's own storage.

–

Files & sharing

Open

Open a .rdm file: a layout, or a full dashboard. It says which as it loads, and only asks about your channel setup if the file actually carries one.

.rdm file

Save layout

The widgets with their images and fonts, and nothing about your car. Safe to share or publish: no CAN ids, thresholds or units travel with it.

.layout.rdm

Save full dashboard

The layout plus this dash's channel setup: CAN decode, thresholds, units. For your own backup, or to set up a second dash exactly like this one.

.dashboard.rdm

Marketplace

Browse and download dashboards other people have built.

Community

File manager

Browse layouts, images and fonts on the device and SD card.

Bench OBD2 simulator and offline-preview rendering toggles — for testing on the desk without a car.

Load layout JSON

Paste a layout in JSON format (e.g. from an AI builder) straight into the editor — no device needed.

Backup All Layouts

Save every layout on the dash into one .rdmbackup file on this computer (layouts only — not images, fonts or channels).

.rdmbackup

Restore Layouts

Put layouts from a .rdmbackup file back on the dash. Layouts with the same name are replaced.

.rdmbackup

Import Local to Device

Copy a layout saved offline in this app onto the connected dash.

Update Firmware

Install a firmware update on the dash over the air.

OTA

Gear Setup: Calculated Gear

Back-computes the engaged gear from live RPM & vehicle speed. Enter your gearbox ratios (in gear order), final drive, and wheel circumference. The signal CALCULATED_GEAR publishes 0 for Neutral / stationary, 1 for 1st, etc.

Wheel Circumference (mm) Final Drive Ratio

RPM Signal Speed Signal (km/h)

Gearbox Ratios (N = 0.000; 1st–Nth in order)

Sync tip: drive in that gear above 5 km/h, then tap Sync. The ratio is back-calculated from live RPM and speed using your wheel circumference and final drive.

Enabled: publish CALCULATED_GEAR

The odometer counts from the Speed signal above. To set its reading, use the Odometer card.

Developer Options

Bench / debugging aids. None of these change your layout or the device's behaviour in the car.

OBD2 Bench Simulator

Fakes a virtual ECU so OBD2 gauges (e.g. fuel level) move on the bench with no car connected. Synthesizes Mode 01 polling, freeze frame, DTC read/clear, and VIN/ECU-name responses. Not saved; off after a reboot.

Offline canvas render

Draw gauges/text in the editor canvas when no live device frame is present. The device's LVGL render is always the source of truth. Editor-only.

Dash RGB565 preview

Simulate the real dash in the offline preview: RGB565 colour banding + firmware-feasible glow (no Gaussian blur / radial halos). Editor preview only.
