Setup your TMU DiY Edition

Congratulations on your AutoPi Dongle, DiY Edition! We're sure that you have some great plans on how to use the device to your liking, but of course, first, you need to set it up. This is a guide that shows the steps that need to be taken to get the device in running condition.

Connecting the Raspberry Pi

The steps you need to take are very simple. In this case, we are using a Raspberry Pi 3 A+, however this can work with a Raspberry Pi 3 B+ or a Raspberry Pi 4.


  1. Mount the Raspberry Pi on the AutoPi, connecting the pins of the Raspberry to the open holes in the AutoPi board.


  1. Connect the USB cable that's attached to the AutoPi board to one of the open USB ports of your Raspberry Pi


  1. Lastly, place the four screws to secure the two boards fastly together.


Connecting to the Cloud

Should you want to use the AutoPi Cloud solution, you can use the image found in this link to flash an SD card. Make sure to download the correct image for your device - since you're reading this guide, you are most likely to be needing to download the TMU image, instead of the GEN 2 image.

TIP: Etcher can write the compressed image directly to the SD card. We recommend using a Class 10 SD card with a minimum of 8GB storage.

Logging in to the device

The device is initially configured with the following credentials:

SSID: AutoPi-Initial
Password: autopi2018

User: pi
Password: autopi2018

We highly recommend that you chnage those settings as soon as you are able to do so.

Getting access to the Cloud

To get your device on the AutoPi Cloud you need to get the unit ID of your device. You can find out your device's ID by reading out the /etc/salt/minion_id file. Once you have that ID, you should write to our support team ( asking for it to be added to the system. Make sure that the dongle has been online at least once before doing this.

Please note: The AutoPi always needs to be powered through the OBD connector to function properly. Powering the board through the micro usb (or usb-c for RPi 4) power plug on the Raspberry Pi could damage your board. If you need to test the AutoPi in a lab environment, we encourage you to get the OBD power connector from our shop.
