As Makers, we simply can’t resist tearing things apart, figuring out how they work and, ultimately, modding things to make them work better, or at least more in accordance with our personal preferences. This is why we can’t resist modules and tools like this DFRobot Original CAN-BUS Shield for Arduino, which allows Makers like us to get into the “brains” of our cars, change around the settings, figure out what makes them run faster or more efficiently and fine-tune the performance to meet our ever-demanding high standards.

This clever little Shield is compatible with the Arduino UNO, Leonardo and Mega boards, and allows you to communicate with your Engine Control Unit via the On-Board Diagnostics standard, to adjust various settings and modify the way in which the car performs. This way, you can mod’ your car to drive precisely how you like, whether you prefer better fuel efficiency or are eager for better performance at high or low speeds. And while it does take some time to learn and discover exactly which settings offer the best results, these tools are a lot more affordable and accessible for the average Maker to acquire and utilise – without the help of a professional.

Bear in mind that if you don’t have the necessary cable, we also stock this DB9 Serial RS232 OBD2 Cable, which is designed to connect the shield to the Engine Control Unit port. Additionally, it’s a good idea to check out DFRobot’s Official Wiki Page for this Shield to see more details on connections, the power requirements and a few other important insights and bits of information that are important in terms of safeguarding your Shield and EMS from damage.
