the thing is that the USB connectors are still just a tiny bit too big and touch the circuitboard next to it (I'm a bit anxious that chips might get hot and melt them). So I want to prevent that by daisychaining them by hardwiring the 5v between the last couple of boards which don't get a midi-controller connected anyways (everything will be done from a single quneo).
Also, I need to save space for future adjustments, like an inbuild midi-thru/splitter and mixer (last 4 boards are going to be 2x2 serial/parellel: 2 for drums&fx and 2 for leads/bass/melody/fx. The first one is gonna be a midi-recorder/presets core)
I've already tried powering them all on from the 5v powerbank, with individual usb-connectors, which seemed to work perfectly. Now it's just the question.. could I power 3 extra boards from a single board.
powerbank has two USB outputs, together they give 2.4A at 5v.
-first output gets an usb-hub, splitting it to power 1 axoloti and the Quneo midi controller (using an external-power usb-Y-splitter to power the quneo directly from the powerbank).
-second output would power a "single" axoloti, which in his turn would power 3 other axoloti's (plus itself of course).
atm I'm not using any of the analogue/digital in/out pins, so this is not drawing any current.
Though I am thinking of adding a couple of sensors/joysticks/knobs/buttons and make a custom receiver module for the quneo that I can switch off/on by midi from the quneo and multiplex between different parameters inside the patch. But I'm not there yet and when that time comes, I might very well just add an extra powerbank.
So the question is only about the last part, powering 3 extra axoloti's from another axoloti that's only 5v powered, without adding any more controllers and how to connect these 5v pins. There are just so many 5v/gnd pins and a good friend warned me about just connecting these together, so yeah... what is it, can I or can't I hardwire when using 5v over usb as powering and which pins should be connected??
