Can I power a second Pro micro using power from the first one to run 2 projects ?
main promicro will be connected via usb and it will be running an oled
second one will be used to run RGB led's
I included an image for the wiring, will this work or fry my stuff ?
Only 2 LED's btw so it shudnt require too much power
I am doing this because of flash memory limit
1st promicro has no bootloader, second one does
Also I am assuming only 1 pro micro should be connected to the USB at a time to avoid shoring ?
so I cant connect them both to usb with ground and VCC linked between 2 right ?
