The chipKIT Pro Edition: What’s the Difference?

If you have ever looked into our chipKIT™ platforms, you may have noticed two of them have a very similar name. The chipKIT Pro MX7 and the chipKIT Pro MX4. While they are both microcontrollers, there are some key difference that should be noted. It’s hard to tell the difference between similar products so we have decided to make a table to list some of the main features between these boards.

As you may have noticed, the MX7 has four times the amount of SRAM as the MX4, along with Ethernet capabilities. It also has double the amount of communication interfaces and two CAN network controllers. While the MX4 is cheaper and offers a couple more peripheral module ports, the better option for most applications is the MX7. This chipKIT board offers more programming and hardware options then the MX4. You will be getting more bang for your buck with the chipKIT Pro MX7.

About Robert Prew

I am studying Electrical Engineer at the University of Idaho. I have always been interested in technology, video games, science and learning new things. I always believed in the saying “if you can't explain it simply you don't understand it well enough” by Albert Einstein. I have a thirst for self discovery and learning new things about myself. Bringing joy or making others feel happy gives me a great pleasure. You can usually get me interested in an activity that has a more hands on approach. I will always try and strive to be the best person I can be.
