RockARM – Hardware Build

Welcome back! If you’ve been following along in my RockARM series, and already 3D printed your RockARM case, then it’s time to fill it with some delicious hardware! In the video below, I take you through the hardware components and assembly, tools and tricks for getting everything built up nicely. After you watch the video, come on back and take a look through the parts list with links!

.. SO! That’s the hardware. Next, you’ll probably want to know where to get it all, right? Here’s links to everything you need. Some of these are affiliate links, which I may earn a small commission in exchange for using them. It doesn’t cost you anything extra, but helps support these projects. What could be easier?!

The shopping list!

There it is! This should get you everything you need to get your RockARM built out and on to the next step! A couple notes: the RockPi4A units are sometimes harder to get on Amazon due to supply, but can usually be cheaper when factoring in the alternative of ordering them from China or Europe with International shipping costs.

Also, it’s worth mentioning that you can use the RockPi4B or C models if you wanted to. The reason I selected the model A for this project is the main difference is, the model A does not have WiFi or Bluetooth, which we do not need for this project; may as well save some money! But, if you are only able to find the model B or C variations, they will work exactly the same!
