Hello,
Just asking because i can't find a real answer for this.
Before i make a pcd for my project i'm going to place the different components as 'ready-to-use' mini boards next to the nano. I'm gonna do it with a larger experimental pcb as a base and drill holes in it for bolting and mounting the mini boards. You know, a pcb with holes and isles.
These 'sideparts' are probably going to be a 16x2 LCD, 2x5V mini relais (max.90mA/relais+optocoupler), 3 low(er) power leds (didn't find any with legs).
It's important to say that i want the hole project to be powered solely from the USB-C port on nano.
That means tapping of the 5V from the 5V pin and GND pin on the nano board.
I'v read that a Arduino nano can handle a max. current of 500mA. Normally if i add all the max possible currents up, i'm safe.
But now (finally) the question: Can i tap of the power used outside the Arduino board somewhere at the USB-C port? It's surface mounted so that seem difficult. (maybe a compact trick with some sort of 'splitter' that can be connected to the female USB port on the Arduino board?) I just don't want to use the small pcb lanes on the Arduino board to draw almost about 350 'isch' mA through.
And if that would be possible to do this, can i use this split off 5V directly on the input/outputs of the Arduino (i suppose yes if there isn't any kind of power conversion on the nano board)?
I need to note here that it is not a original Arduino board but that won't make many difference because the original one has also a surface mounted USB-C port.
Feel free to let this topic be moved if it's in the wrong category.
THX!
