3.3v or 5vAdd the link for 5v, remove it for 3.3vThe processor on the USB-ISS is equally happy running from 3.3v or from 5v. With the LEDs it takes up to 20mA so when 5v is selected by linking the power select pins, the USB-ISS module can supply up to 80mA to external devices. When the link is removed a 3.3v regulator supplies the power. This regulator is capable of 50mA, so when running at 3.3v up to 30mA is available to your circuits. If your application requires more than this, or has its own supply, then leave the 3.3v/5v pin unconnected. Do not apply your own voltage to this pin.
0v GroundThe 0v Ground pin must be connected to the 0v (Ground) on your device.
Dann hänge ich von der externen Stromversorgung für den Colorduino nur noch den Pluspol an?
