Which Model of the Raspberry Pi Do the Courses Use?

Our robotics course kits use a Raspberry Pi 3B as it is by far the best model for electronics and robotics projects. We do get questions from users about the newly released Raspberry Pi 4 however it's important to understand that newer isn't always better. Which model will best suit your needs is largely dependent on what you will use the Pi for (robotics projects vs. a personal computer replacement for example) and also your personal skill level. The primary issue with a Pi4 is that it has very high power requirements. It needs to be plugged into a wall as a standard battery pack won't meet it's needs. It really isn't any fun to have a robot that has to be plugged in though.
