Hi, I am looking to build an eboard and have purchased a Loaded tesseract, Caliber trucks, Orangatang Kegels, DIYE Motor Mount, Torqueboards 6355 190kv motor, Torqueboards pulley/belt kit, and Torqueboards vesc. I really love the Boosted board remote and I wanted to use something similar for my own build so I was looking at this: https://www.thingiverse.com/thing:2454391 . I am currently 3d printing all of the components and have all of the internal components on order from China and was wondering how the receiver unit would work. Could I use an Arduino pro mini instead of the nano listed in the project files? Also could the Arduino (either nano or pro mini) be powered by the vesc itself or would it need an external battery?
