Current Gauge
Controller

Drive analog gauges from modern CAN data.

A 4-channel controller that drives 3-pin dual-coil analog gauges from CAN bus data, with DBC signal mapping, response curves and per-gauge calibration.

$250

USD. Shipping and applicable taxes are additional. Coming soon. Orders are not open yet.

Made by Current Labs.

Four gauges, one compact unit.

Every channel is an analog constant-current sink that emulates the variable resistance of a sender, so the gauges you already own read modern CAN data. Calibrate each channel to its gauge once, map any signal on your bus to it, and the controller does the rest. It even sleeps when your vehicle does.

Gauge channels
4 independent outputs
Gauge type
3-pin dual-coil analog gauges (fuel, temperature, oil and others)
Drive
Analog constant-current sinks, 0–148.7 mA per channel

Configuration
USB and the Gauge Configurator desktop app

Guided Empty/Full for each gauge, stored on the unit
Response curves
Up to 8 interpolated points for each gauge
Failsafe
Hold, fixed position or needle off on signal timeout
Power
12 V vehicle input; regulated 8.8 V gauge supply (600 mA)
Sleep
Sleeps when the bus goes silent, wakes on CAN activity
Connector
DE9
Firmware
Updated in the field over USB

Keep your gauges. Ditch the senders.

Most paths to CAN-driven instruments replace the cluster with a digital dash or a full gauge swap. The Gauge Controller takes the other path: any signal already on your bus, mapped to any analog gauge you already own, with a curve you define. No new cluster, no adapter senders, no compromise dash.

Hardware features.

Four gauge channels

Each channel is an analog constant-current sink (0–148.7 mA) that emulates a sender. It drives a 3-pin dual-coil gauge smoothly, with no PWM flicker.

Any signal, any gauge

Load a DBC file in the Configurator, pick any broadcast signal on the bus and map it to any gauge with a response curve of up to eight points, including tank-shape correction and non-linear senders.

Silent on the bus

Receive-only on CAN at 125K to 1M baud, with hardware frame filtering. It reads what your ECU already broadcasts and transmits nothing.

Per-gauge calibration

A guided Empty/Full calibration in the desktop app matches each channel to your exact gauge, and the unit stores the result.

Fails safe, sleeps light

On signal loss each gauge holds, parks at a set position or drops its needle to rest. When the bus goes quiet, the unit sleeps and wakes on CAN activity, so it is safe to leave powered.

Configure and calibrate from your desktop.

Gauge Configurator is a free desktop app for macOS, Windows and Linux. Connect over USB to load a DBC file, map signals to gauges, shape response curves, run the guided Empty/Full calibration and install firmware updates, all from one place.

Quick start.

  1. Wire 12 V power and ground, connect CANH and CANL to the bus of your vehicle, and run each gauge to a sink channel and the regulated 8.8 V gauge supply.
  2. Connect over USB and open the Gauge Configurator desktop app for macOS, Windows or Linux.
  3. Set your CAN baud rate, load the DBC file of your bus and map a signal to each gauge with a response curve. Then run the guided Empty/Full calibration.
  4. Save the settings to the unit and disconnect. The controller drives your gauges from the bus and sleeps when the bus goes quiet.

Gauge Configurator

Current Gauge Controller firmware

The easiest way to update is from Gauge Configurator, which installs firmware over USB. This image is for manual installs and recovery: the USB bootloader flashes the .bin file.
