Presenting the AutoPi Telematics Unit (TMU) Pi3
3rd Generation device

Built on top of the Raspberry Pi 3 model A+
Our first generation telematics unit

The 3rd generation AutoPi device

Same base features

But with a lot of additional processing power

Upgradeable to Raspberry Pi 4

The AutoPi TMU Pi3 ships with the Raspberry Pi3 Model A+, but has been designed for the future. This means that it is easily upgradeable to the Raspberry Pi 4, if you need even additional processing power.

Support for automotive ethernet with small modification

When upgraded to the Raspberry Pi 4 or the Raspberry Pi 3 model B+, the AutoPi TMU Pi3 can support ethernet as found in many newer cars, such as BMW's.

Better access to I/O and status LED

We have improve the design with easier access to all connection options. Access HDMI, USB, Audio Jack from the side of the device. We have also added two LEDs for power and status indication.

Support for gyroscope on larger orders

We made room for expanding the AutoPi with a gyroscope. The Bosch Sensortec BMG250 can be added on larger orders.

Leading edge hardware components

Merged into a compact OBD Telematics Unit

Raspberry Pi™

An embedded Raspberry Pi delivers the computing power which enables the AutoPi Telematics Unit to do practically anything. It easily runs a full Linux operating system alongside with demanding applications.

4G/3G Modem

The built-in modem enables Internet access through a 4G/3G connection, depending on your model. Our future-proof design allows easy replacement of the network module with other expansion boards supporting standard Mini PCI-Express socket.

GPS Module

Real-time tracking of vehicle position, speed and altitude. Includes A-GPS support that significantly improves the startup performance and time-to-first-fix.

OBD Chipset

Advanced on-board OBD-II chip that supports communication with all OBD-II compliant vehicles.


Embedded 3-axis accelerometer enables real-time measurement of all horizontal and vertical G-forces applied to the car.

Voice Speaker

Playback of voice notifications based on real-time data from GPS, accelerometer, car diagnostics or any other device attached.

USB Ports

Connect USB peripherals to the provided micro USB 2.0. For example, WiFi and Bluetooth devices or even a HD camera which can be used as a dashcam.


Plug in a touchscreen or any other display device through the supplied HDMI port. An essential feature when building an in-car computer or entertainment system.


Integrate with and control auxiliary systems in your car. For instance a third party electronic boost controller or a water/methanol injection system. An useful option for advanced IoT projects.


The AutoPi is extensible through Bluetooth 4.2 with Bluetooth Low Energy (BLE). Connect a range of third-party products through this.


Additional connection options are available through build-in 2.4GHz and 5GHz IEEE 802.11.b/g/n/ac wireless LAN.

Native Real-time Clock

For those needing precise timing and accuracy, we have added a native Real-time clock on the device. This means that even when offline, the device will always maintain correct timing.

Powered by a Raspberry Pi 3 model A+

The revolutionary low-cost mini computer

Computing Power

Equipped with a Broadcom BCM2837B0 64-bit Quad-core CPU at 1.4 GHz, 512MB RAM and also an integrated GPU. This is enough to do advanced tasks like HD video recording and playback. It is even capable of image recognition and machine vision.

Operating System

Raspbian is the official supported OS. It is an adaptation of the entirely free Linux distribution; Debian. The AutoPi Telematics Unit comes with a pre-installed SD card containing the AutoPi Core based on Raspbian. If you want, you can easily run your own software and OS.

Connectivity Options

Provided with HDMI, USB and also 40 GPIO pins. The GPIO pins can be used for all sorts of purposes; most can be used as either inputs or outputs. 16 of the pins can be accessed directly from the outside of the AutoPi Telematics Unit enclosure. This is done through a connector cable, which purchased together with the AutoPi Telematics Unit.

Extensive Community

With over 12 millions devices sold worldwide since 2012, a huge Raspberry Pi community exists today. It is easy to find information, share ideas with other like-minded and get help. The Raspberry Pi has even gone into space, as it was used on the Intenational Space Station.
