How Macchina approaches supporting user development with our products.

Macchina products can be used by a wide range of people for a wide range of tasks. As great as that is, it make supporting user development a challenge. Please keep in mind the below are the best practices we have come up with for trying to help as many people as possible with our small team.

Step 1 (start here)

The first thing we need to do is try to identify the type of help you need and how to direct you within our company or community.

  • Did you find an issue in a Macchina produced library or other related code? Go here

  • If you are looking to partner with Macchina or have us work on your product? go here

  • Are you an experienced engineer/developer with a technical question hoping to talk with a Macchina Engineer? Go here

  • Do you have shipping related questions? (invoice, tracking,...) go here

Documentation Request

This is the easiest way to get support from us. If you think we are missing something from our docs, then please let us know and we will try to get it added. Please note that questions like "how do I tune my car" are not in scope for the documentation. Good examples include how to send a CAN message, how to blink an LED,...

To submit a doc request please email us the below information to,

  • Subject: Doc Request

  • Relevant product SKU(s):

  • What are you trying to do: (please be detailed, this will help us understand the use case)

  • What document/tutorial would help you: (be specific)

Submit a GitHub Issue

If you found an issue that has to do with a specific library or code base, raise an issue in the appropriate repo here:

We are always looking for ways to engage the community and leverage everyone's collective knowledge to build better open source libraries, examples, and projects. Right now we are considering adding a bounty program. If you have experience with something like this or other community building methods please send us your thoughts to , Subject: Dev Community Feedback.

Defective products

We don’t want to ship things that don’t work, so we test every unit before it leaves. That doesn’t mean customers never have issues, but it should be rare. If you are having an issue, please make sure you have eliminated the other possible causes (computer, cable, sd card, or other issues).

If you still believe our hardware is the issue please reach out to us at,

  • Subject: Product Defect

  • Order Number: (from your purchase confirmation email)

  • Current address:

  • Issue Description:

  • Pictures: (if you see visable damage)

We will send you a return label and get the replacement processed.


Sometimes you let the magic smoke out when trying to build cool things. We have seen people come up with interesting ways of accomplishing that. We like to see what happened.

Please email (, Subject: Magic Smoke Issue) us pictures of the hardware (especially if you can see an obvious issue) and what you were doing with the hardware, this is mostly for future design planning.

Most issues are not worth trying to fix. If we want to inspect the issue ourselves we will send you a return label.

If you want to replace the unit we will offer you a one time discount code (unless you make a habit of this).

International orders

We prefer to do international shipping through our resellers. We are willing to ship bulk orders internationally,

Sparkfun (Worldwide)

Digi-Key (US only)

Mouser (worldwide)
