Hi there, I’ve been dabbling in microcontrollers and diy midi interfaces. The nano is a 3.3v controller but it is powered by the 5v coming from the usb. Attached are photos of a panel I’m building to interact with a raspberryPi, pisound audio interface by blokus, my Elektron boxes, and arduino satellites that will contain sensors sending data back to influence audio signal processing via Pure Data running on the Pi.
