A 7-inch CAN dashboard with a full layout editor served by the dash itself over Wi-Fi, so you build your layout in a browser tab on your phone. Drop-in replacement for analogue gauge clusters. RDM Studio is free, with no subscription. Built for performance vehicles, track builds, drift cars, off-road rigs and anything with a CAN bus worth watching. Key Features The editor lives on the dash. Connect to the dash's own Wi-Fi hotspot and the layout editor opens in a browser tab on your phone or tablet. Drag widgets, set alarms, map signals, push to the dash. No cable, no laptop, no internet connection needed. Set it up before it arrives. Desktop RDM Studio runs with no hardware connected, renders every widget, and has a simulate mode that drives the gauges with fake data. Windows, macOS and Linux, free with no subscription. The channel catalogue is built in, so your whole layout can be ready while the dash is still in its box. Free firmware updates over Wi-Fi. No cable, no flashing tool. You push them when you decide to, and your layouts stay on the dash. 128 signal channels. Read any standalone or factory CAN bus. DBC file import for anything custom. Transmit on CAN, too. Map any on-screen button or toggle to a CAN message, turning the dash into a programmable keypad. Trigger ECU functions, body controllers, auxiliary outputs or relays from the touchscreen. ECU presets built in. Haltech Nexus and Elite, Link G4+ and G4X, MaxxECU, MegaSquirt MS3-Pro, ECU Master Black and Classic, Ford Falcon BA and BF, and the first-series Toyota 86, Subaru BRZ and Scion FR-S (2012 to 2020), plus standard OBD2 for almost any car built since about 2008. Link G5 support is coming. Onboard data logging. Records at 1 to 200 Hz (10 Hz out of the box) to the dash's own memory, so no card is needed, or to a microSD card for longer sessions. Standard CSV, so it opens in Excel, Python or whatever you already use. 13 widget types, several layouts on one dash. Meters, bars, RPM bar with shift light, indicators, alerts, panels, gauges, images, text, buttons, toggles, arcs. Keep more than one layout on the dash and switch between them. 800x480 IPS touchscreen. Capacitive multi-touch, 16-bit colour, around 50 fps, under 20 ms from the bus to the screen. Auto-dims from a CAN headlight signal when the vehicle exposes one. No crimping. The plug is an eight-way push-in terminal block with release tabs. Strip the wire, push it in, done. What It Does The RDM-7 sits on your vehicle's CAN bus and turns what is already on there into a dashboard you want to look at. Replace a cluster of analogue gauges, keep one layout for the street and another for the track and change between them on the move, log a session, and push firmware over Wi-Fi when you decide to. What The Install Involves Twenty minutes with a plug-in adaptor, including tying the cabling in properly. About an hour wiring it in yourself. Four connections: 12 V switched ignition, chassis ground, CAN High, CAN Low. Fuse the 12 V feed at 2 A. Around five seconds from key-on to numbers moving. The RDM-7 is for 12 V vehicles only. The plug on the dash is eight-way. Four pins arrive populated and the other four are optional: left and right indicator off the factory dash plug, and a fuel sender. An ordinary resistive float-arm sender is two wires and nothing else. Who It's For Anyone running a modified, standalone-EFI or purpose-built car who wants a proper digital dashboard without the price tag of a race-team unit. Street builds, drag cars, track days, drift cars, project cars, 4WDs, kit cars, and classics with a modern ECU swapped in. If it has a CAN bus, the RDM-7 belongs on it. What's Included RDM-7 Digital Dashboard Display A 20 cm lead from the dash's plug to a DTM-4 Style connector RDM Studio software, free, no subscription 12-month warranty Sold separately: what joins the dash to your car. Wiring it into an ECU? The 2 m DTM-4 Extension with bare wires ($40) is added for you when you buy the dash, and you can untick it. Plugging in? Choose the RDM-7 ECU Adaptor (Haltech, Toyota 86, OBD2) or a Link CAN cable instead. Step 1 on this page picks the right one for your ECU. No microSD card is needed or supplied. Logs save to the dash's own memory, up to 1 MB per file. For longer logs, add a microSD card formatted FAT32. The dash does not read exFAT, so a large card straight from the packet will not mount until it is reformatted. Compatibility Nobody gets a dead end. If your ECU is one of the presets above, there is a dedicated profile for it. If it is not, and your car was built after about 2008, the RDM-7 reads standard OBD2 out of the box. Past that you can import a DBC file. Past that you can build channels yourself. All three are in the firmware already. A dedicated profile reads more, and reads it faster, which is why we keep building them. Factory ECUs hide their signal layouts, so each one has to be worked out car by car. Don't see your car? Tell us what you are running and we will queue a profile for it. We build the ones our customers ask for first, and once a profile exists it reaches every owner over Wi-Fi at no cost. Display, logging and CAN transmit only. The RDM-7 reads, displays, logs, transmits and shares data. It does not tune your ECU.
