M2 by Macchina is a key to unlock the control center of your car. Once you are in, M2 can then be used to make changes and tweaks to your car. You can do anything from simple projects like stopping that annoying ding to more complex upgrades like unlocking more horsepower or improving fuel economy.

M2 arrives to you as a blank key - you have to cut it yourself. Learning how to cut that key reverse engineering, writing code, and plain-old tinkering is the fun and challenging part, but don't worry you can do it, because a community of car nerds already exists.

The community supports each other and you by sharing what we have learned and discovered together. M2 is an open source automotive interface that can take your car to the next level. Use it to unlock your car's potential or as a development platform for your next product. M2 was engineered to facilitate many uses for most cars.

We set out to build a platform of modular pieces that works for beginners and professionals alike. We crammed all of this in a small format at an affordable price. You can even reprogram M2 wirelessly. Connect your car to the web, phones, satellites, IoT devices, or the cloud. Many applications have different wireless needs so we went the route of making it completely modular. Pick what you need when you need it. M2's breakout board lets you use your own processor board and save money - just wire it up and get coding!

There are many advantages to using the board we created specifically for M2, but you may find applications where you prefer something else. In that case, we still want you to be a part of the community!

M2's modular approach allows for simple and inexpensive upgrades. The platform consists of three main interchangeable components: an XBee board, a Processor board, and an Interface board. With this modular approach, you have an almost infinite number of possible combinations. So, we are sure you will be able to create the exact feature set your project requires.

Upgrades and changing your mind will be painless and inexpensive. The one thing that all car hobbyists can agree on is that playing with cars isn't cheap. Open source hardware is the answer!

M2 is feature-packed and can go toe-to-toe with more expensive professional solutions. We keep our prices as low as possible so that the community can be as large and inclusive as possible! We decided to make further improvements to M2 by using the High Speed SD card interface and writing the appropriate firmware libraries to allow for faster data logging. We also added several LED options and a couple switches for a more pleasant development experience.

The goal for M2 is to interface and communicate with as many cars as possible. Automotive environments require M2 to be seriously strong, so we built in plenty of protection circuitry. Lastly, we have 6 general purpose driver circuits, each of which can source and sink up to 1 amp of current at 12 volts! This makes M2 useful for cars that predate automotive networks. For M2 and Macchina to reach its full potential, we need a large, active, and engaged community. Open source hardware and software allow us to more quickly develop and iterate our designs with community feedback.A prototype is a preliminary model of something.

Projects that offer physical products need to show backers documentation of a working prototype. Though the development process can vary for each project, these are the stages we typically see:.

Explorations that test ideas and functionality. Demonstrates the functionality of the final product, but looks different. Looks like the final product, but is not functional. Appearance and function match the final product, but is made with different manufacturing methods. Appearance, function, and manufacturing methods match the final product. M2 by Macchina is an open source automotive interface that can take your car to the next level. Use it to unlock your car's potential or as a development platform for your next product.

We have been getting a lot of questions along the lines of "Can M2 start a car? How we accomplished this is explained in section 11 and update 3.

M2 has the protocols and libraries to work with any car that isn't older than Google. M2 is based on the Arduino Due. If you have any previous experience with the Arduino platform, you can leverage existing code, libraries, tutorials, and established communities. Are you familiar with open source hardware but new to using it with cars? We are working together to bundle M2 with the book at a great price.

That's not the end of our collaboration: Craig has also joined the Developer Program to help improve M2! The area under the dash and the gaps under the hood are very small, so we made M2 as tiny as we could 2. Connect your car to the web, phones, satellites, IoT devices, or the cloud.

We think it works great for many of the applications M2 was designed for, so we have built a bundle option to get you working with it right away. M2's breakout board lets you use your own processor board and save money - just wire it up and get coding!

M2's modular approach allows for simple and inexpensive upgrades. The one thing that all car hobbyists can agree on is that playing with cars isn't cheap. Open source hardware is the answer! M2 is feature-packed and can go toe-to-toe with more expensive professional solutions feature-for-feature!

A couple years ago, a few of us got together to work on a fun side-project: we turned an old Ford Contour into an electric car.

We replaced the existing gasoline motor with an electric motor and the fuel tank with batteries. Rather quickly we realized that a major obstacle was convincing the various computers within the car to not be too upset after its engine had gone missing. Our challenge stemmed from the closed, unpublished nature of modern-day car computers. We started Macchina to solve this problem. Eventually, we realized that others might benefit from a product like M2, not just for electric car building but for more general applications.

Thankfully, several of us worked in the consumer electronics industry and already knew how to take an idea through prototyping and into production. We launched a business to focus on production and further development. Earl and Josh run the show. Josh manages technical developments, while Earl manages everything else.The Interface Board for P1 is exactly the same as M2. It contains both the power supply circuitry and the automotive interfaces required to communicate with your car.

This includes:. Every P1 has a pin general purpose "expansion" connector that provides even more connection options. See the schematic for actual pinout details. Refer to the following diagram for pin 1 location. The following table shows what the function for each pin:. OUT 1. OUT 2. OUT 3. OUT 4. OUT 5. OUT 6. CAN bus is a vehicle bus standard used in most cars built after It is a message-based protocol that allows modules within a car to communicate with one another.

While the physical layer is understood and open, the actual meaning of the messages sent over the bus are not. While some messages are legislated to be "standard", the majority of CAN messages in your typical car are not well documented.

Here is a typical example:. CAN bus connections can be found on either the pin OBD2 connector on the under-the-dash P1 or the pin connector used by the under-the-hood P1.

Typically, LIN would be used to control and monitor lower-priority devices such as seat positions, door locks, radio and illumination. LIN bus connections can be found on either the pin OBD2 connector on the under-the-dash P1 or the pin connector used by the under-the-hood P1. Use following Commands to see if the Lin-Busses are working:.

This protocol is similar to RS but at different voltage levels and on a single, bidirectional line. Some cars require a secondary line sometimes referred to as L-Line.In about a week I will want to start trying to connect to my '03 Pickup which uses j VPW and am willing to help develop the library but need to know if there is indeed one that has been atleast started?

Im curious about this too…I think theres an Arduino library somewhere out there that emulates ELM functionality…but Ive never used it. Looks promising. May have to do some research and see if it can be ported over to M2. I am sure it should be able to once I understand how the hardware is put together.

Rodney - Thank you for the willingness to take this project over! I have a large project to customize an '03 Chevy Avalanche that will rely heavily on using the data bus and have been tinkering with a couple STN based ELM compatible devices up to now.

I have protocol documents that explain how it works and some command structures so I am on the way. Just need to understand how the hardware works and go from there. I am not interested in the ford version of the protocol and have no resources for that.

Ben, can you let me know what pieces you actually used to obtain your test bed? I may attempt to build something similar instead of using my truck directly. Might be smarter…. I have a spare dash cluster I can use but thinking more of the bare necessities I would need. I could always buy a junked truck and strip out everything but not the simplest solution. It was actually very impressive for the time when it was introduced.

And then just get yourself a 12volt bench power supply, an OBD port, and get to wiring it all together…. You dont NEED multiple modules in order to get them talking. You could just power up that spare cluster you;ve got there and start messing around….

Then you can watch messages that the Tech 2 sends out when you use the Tech 2 to command the truck to do things fold the mirrors, windows, horn, yaddyayayda …and just copy those messages and incorporate them into your code. Class 2 is super easy to reverse engineer because the header tells you everything you need to know. Its 3 bytes.

So you basically just watch the sender ID and you can tell which message is coming from which module. Once you figure that out…you can write a little Arduino program to send whatever text messages you want to the instrument cluster.

I think you can send anything up to 20 characters, thats the limit of the DIC display itself I thinjk. My truck is an Z71 off road truck.

Has pretty much everything else other than the rear entertainment module. The cluster I have is complete other than the fact it has no actual motors or gauges on it. I stripped it to fix my cluster before giving up and sending to someone.

Just need motors and needles for it. I have some j documentation and part of it gives the GM module ranges. Since I will be replacing my radio and using a computer I hope to find out how to do the steering wheel controls Although I have to add them and things like rear seat audio and XM radio. Those all use data bus commands to communicate with the radio. Rear seat audio uses the rear-speaker outputs from the radio which double as secondary audio source.

So when you hit RSA on, the RSA module sends a data message to the radio, and the radio switches the rear speaker outputs from being rear speaker audio, to be the secondary audio source. The rear speaker outputs from the radio to the Bose amp are looped through the RSA module, so the RSA module can cut off the output to the amp.We use optional third-party analytics cookies to understand how you use GitHub.

Introduction to M2

Versions of M2. Common Issues. A0 Projects.Boss David Wagner will have all the information he needs to deal with the threat of Brighton dangerman Pascal Gross. Philip Billing and Jon Gorenc Stankovic remain sidelined, while Michael Hefele has been back out on the grass this week. As you might expect from a Hughton outfit, Brighton have been quietly going about their business and can be happy with their start to life in the top flight.

Despite a 5-1 reverse to Liverpool in their last outing, their defensive record of seven goals shipped in as many away games puts Town to shame. This record will be tested over the Christmas period with trips to Tottenham Hotspur and Chelsea, so they will see Huddersfield as a good chance to bag points. These two have been familiar foes of late and will have faced each other in all but one of the last 11 seasons.
