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 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 improved 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 can be added on larger orders.
What is the Telematics Unit?
Telematics unit or also known as Telematics Control Unit (TCU) refers to the embedded system, which is on board of the vehicle and connects to the vehicle and the cloud.
Typically, the telematics unit can be connected via OBD2 port in the vehicle and the data can be seen on the laptop, smartphone, dashboard or special obd2 scanner.
The telematics unit collects telemetry data from the vehicle, such as speed, position, connectivity, engine data and more. The TCU is very beneficial for any use of vehicle, regardless the purpose of the vehicle.
However, it can bring lots of cool features and improve driving experience of a driver or the whole family. Some of the most favorite features areheads up display, theft detection, car WIFI hotspot and voice commands recognition.
Telematics unit is commonly used in businesses, more specifically in fleet management, as it improves the efficiency of the fleet (group of vehicles that engage in one common activity) and therefore, the logistics of the actual business.
Telematics Unit uses satellite navigation (GPS), as well as electronic mapping tool to monitor the position of the vehicle at all times. It is possible to monitor it even if the vehicle has been stolen.
Due to its Broadcom BCM2837B0 64-bit Quad-core CPU, 512MB RAM and integrated GPU, AutoPi Telematics Unit supports recording and displaying HD resolution videos. Use it for image recognition and machine vision in advanced projects.
Filling the gap (optional on large orders)
Earlier generations use accelerometers to detect the orientation of the unit. As an optional feature, AutoPi TMU Pi3 accelerometers can be expanded with a gyroscope to fill in its lateral orientation during a movement.
This gives additional information by tracking the rotation and twist of the device. This gives a both clear and responsive data output on the device’s physical orientation.
Accessing connectivity where others can’t
AutoPi TMU Pi3 is designed to be easily upgradable to a Pi 3 Model B+ or Pi 4 and enable high speed data transmission and bandwidth via Ethernet connection.
One of the main advantages of Ethernet is that it is typically less vulnerable to disruption, therefore, offers a high-performance network and greater degree of network security. In newer cars, Ethernet runs alongside traditional vehicle cabling used for in-car connectivity, allowing all vehicle components to be securely connected.
Benefits of Telematics Unit
Telematics Unit can bring you lots of benefits. There are many more additional aspects that we do not even realize telematics unit is capable of.
One of the automotive industry trends is the connectivity and AutoPi Telematics Unit can actually connect your vehicle to the cloud and bring you additional features that you did not even know exist.
Connectivity - Capable of connecting your vehicle to cloud, collect data and 'communicate' with your vehicle. It is possible to connect several vehicles to monitor them at the same time.
Antenna optimization - It is possible to adjust antenna power optimization with better sensing, diagnostics and low noise.
Reliability - Telematics Unit is reliable, efficient and offers fast data transmission that enables communication to other systems in the vehicle.
Driving assistance - AutoPi Telematics Unit can improve your driving experience. Check out our use cases page, where you can find lots of examples on how TMU can help you.
Despite the large number of benefits that Telematics unit brings, people still think the price is too high and is not worth it. If you are barely using your vehicle, and you do not really pay much attention to the health of your vehicle, then it might be true.
On the other side, if you are using your vehicle regularly, or it is part of your daily job, then it is definitely worth it. Think about how much you spend at a mechanic a year and what are your vehicle's features or functionalities. Then consider everything that Telematics unit brings you.
It improves your vehicles' 'health', notify you of its current situation, improves your driving experience, gives you lots of additional possibilities and on top of that, it can even help your whole family while using the vehicle. There are seriously only benefits for having a Telematics Unit in your vehicle/s.

Leading edge hardware components
Merged into a compact Telematics Unit
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.
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.
Real-time tracking of vehicle position, speed, and altitude. Includes A-GPS support that significantly improves the startup performance and time-to-first-fix.
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.
Playback of voice notifications based on real-time data from GPS, accelerometer, car diagnostics or any other device attached.
Connect USB peripherals to the provided micro USB 2.0. For example, WiFi and Bluetooth devices or even an 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 built-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+
Tailored to your requirements
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.
Raspbian is the officialy 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.
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. Sixteen 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.
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 International Space Station.
