Welcome to the future home of the highest quality car information on the internet.

Quick Start

If you are looking to get your EON up and running see the following guides




The EON is the three things that you need for your car. A dashcam, navigation, and music. The EON is the best dash cam for your car. It allows you to help self driving cars, record your drives, and unlike phones running Chffr in the summer the EON won't overheat with an included built in heatsink and fan to help keep it cool

  • A Dashcam
    • Your iPhone or Android phone can run Chffr but the EON can run ChffrPlus.
  • Navigation
    • Let's face it most car's built in GPS maps are bad. That is why with an EON you can use the best navigation app out there, Waze.
  • Music
    • We all like good music in our cars and with an EON you can listen to all the tracks you want through Spotify

You can buy one here

How to install an EON: Installing EON


Panda is a universal car interface. Panda's allow you to talk to your car over USB and WiFi. It supports 3 CAN buses, 2 LIN buses, and 1 GMLAN. The software is 100% open source and is developed openly. Top contributors will be offered a job, has a budget to fund this development, as we win if cars are more open and easier to talk to.

See the panda wiki page for more info. Pandas are now for sale at


Giraffe connects Panda to vehicle control buses that are not exposed via the standard diagnostics port, usually the LKAS and ACC sensors and commands live on these buses. There are currently 2 versions, one for Honda and one for Toyota. Double check the connector and make sure it is compatible with your LKAS camera.

Buy Giraffe in the shop for $60: Honda Toyota

Or build it yourself or modify it for other makes of cars

See Installing Giraffe for help installing it


neo is an open source robotics research platform. It is powered by a OnePlus 3(3T) smartphone and an STM32F205-based CAN interface board. EON plus Panda is capable of everything that NEO is capable of.

See the neo wiki page for more info.



Chffr is like a Fitbit for your car. It's a dashcam app that powers's self-driving technology. For every minute you record you get comma points. Pair it with panda and view your compatible car's messages in cabana. It is available for Android and iOS

See the chffr wiki page for more info.


ChffrPlus is the default NEOS program for the EON. It doesn't allow for self driving but it does allow you to run Spotify, Waze, and Chffr all on the same phone with a great UI.


Openpilot is an open source driving agent. It is capable of controlling the gas, brake, and steering on certain cars, reaching up to 6 minutes with no user action required (besides paying attention!). Currently works with Panda and Giraffe on some Honda and Toyota cars with many more Honda and Toyota ports currently underway. See How it works and Installing OpenPilot on the EON for installation instructions for EON


Cabana is a web application that allows you to inspect, label, and plot vehicle data collected by panda which can then be saved locally or committed to GitHub in the form of a dbc file. Cabana syncs panda data with chffr data for an extremely user-friendly reverse engineering experience. This allows you to easily scrub through video segments to target a specific driving event, such as braking, and label the associated CAN messages.

The NEO and the EON run NEOS, a heavily modified version of android. See NEOS for more info.


If you are having any issues with Chffr, Panda, or Neo please refer to the links below

How to Help

There are 4 ways to help:

  1. If you have a car listed here your car is supported by OpenPilot and recording your drives with chffr (or OpenPilot) will help build data to improve route tracking and sensor understanding
  2. If you have a different new model Honda or Toyota that has both lane keeping assist (LKAS) and adaptive cruise control (ACC), there is probably already a port underway to your car. You should search/ask on the forums and get on Comma Slack and help with the porting.
  3. If you have a different make car with LKAS and ACC, you can get the Panda and use Chffr to record your drives. If you're a hardware hacker, check out the Giraffe source repo to start adapting Giraffe to your car. You can also use Panda and Chffr to start recording drives now and decoding what CAN messages are available from the diagnostics port.
  4. If you don't have a LKAS or ACC car, you can still help the research project by getting a Panda and recording your drives with Chffr! You will gain Comma points and help bring the future of self driving cars closer.

And if you don't have a panda, you can help document which cars have ACC and LKAS. This is a great list to start from.
