Take power from a PC with this handy USB lead. The lead is 1m long and has pre tinned red and black wires which connect to the 5V pins on the USB plug.
The USB standard allows peripherals to draw 100mA each, which is enough to power an LED or most simple circuits.
This power lead is also ideal for use with 5V, 500mA mains power supply. This combination is ideal for powering static projects that can be set up near to a wall socket.
