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.

Features:

  • Take power for you project from a PC.
  • Pre-tinned colour coded leads.
  • Ideal for use with the 5V, 500mA mains power supply.

Contains:

  • 1 x USB Power Lead.

    Asked by Josh on October 24, 2016 12:00 am
    Answered by the admin Hi Josh,


    PICAXE needs between 3V and 5.5V so this would power the circuit without the need of a resistor.

    Q Can this lead be used to power a small strip of your LED strip (max 3)
    Asked by Tunde on September 9, 2016 12:00 am
    Answered by the admin Hello, the LED strip requires a forward voltage of 12V’s, a USB lead will provide 5V’s, so unfortunately the forward current wouldn’t be high enough to power the strip.

    Asked by Ben on September 11, 2015 12:00 am
    Answered by the admin Yes you could use this lead to power our 5V LED's. Although in theory this should be fine without a resistor, it would be advisable to use a low value resistor, just in case the power output of the USB is slightly higher than 5V’s

    Q Hi there, would a 3.v bulb lamp in a holder work off this USB lead?
    Asked by Chris on April 11, 2014 12:00 am
    Answered by the admin The 3.5V lamp will have a bit of tolerance in terms of the maximum voltage, however I'd expect that this might be 10% above the rated voltage of 3.5V. It certainly isn't specified to run at 5V, so no it won't work. Depending on the application, you might be better using a white LED as it will use less current and it's easier to operate at the required voltage by means of a current limit resistor. For more details see white LED USB lamp in the related products link.

    15. Could one use the Low inertia motor with this USB power lead? I know it functions between 0.7-5V, but would there be enough current? Also, would it work with the Solar Cell, without charging (in the UK)? Many thanks in advance.

    Asked by barnaclefred on July 13, 2012 12:00 am
    Answered by the admin Yes the low inertia motor would be fine to be used with the USB lead, as well as being low voltage it is also low current at about 10mA. The question as to if it would work with our solar cell is a little more tricky to answer. If the application doesn't load the motor, for instance using it as a fan then it should be fine. However if you plan on driving something where the motor is going to be under a heavier load I'd definitely give it a try before deciding if it?s a good idea. All solar cells are specified to make them look good and if they once managed to do 5V at 50mA then that is what they will be quoted as. You will never manage to get a solar cell to deliver the amount of power the specification suggests it is capable of.

    Asked by Jim Jenner on June 10, 2011 12:00 am
    Answered by the admin The low torque motor you have suggested is a 3V motor that will work up to 4.5V and the USB port is a 5V port. Something that is connected to the USB port should only draw 100mA unless it has communicated with the PC and negotiated a higher current, in which case it can take 0.5A. The typical current of the motor is 1A so as well as being too lower a voltage it will also take too much current. The other thing to consider is that educational motors are electrically noisy and that PCs are more sensitive, though generally this will be the lower voltage supplies rather than the 5V supply. So in order to keep inside the motor voltage specification and below the USB port current specification I'd suggest using a low inertia solar motor. This will also have the advantage that it is electrica lly cleaner than the other motors, but it is more expensive. The stock code for this motor is 2506.

    Asked by Andrew Headon on May 23, 2011 12:00 am
    Answered by the admin The USB interface is a 5v supply and 2 data lines. So if you have a USB device that you need to power it would be possible to use a 5V supply and connect it to the device via the USB port. You are therefore right that with the appropriate adaptor this lead could be used. However DO NOT use a 9V battery as you will damage the equipment that you connect to it. The voltage should be between 4.75V and 5.25V and capable of delivering 0.5A.

    Q Can i run a 3v buzzer directly off the usb safely for a steady hand game project?
    Asked by GarethJones on April 13, 2011 12:00 am
    Answered by the admin The computer USB is a 5V supply. It would depend on the buzzer you had in mind as to whether it would work. The white piezo buzzers we sell are designed to run off a 3 to 24V supply so would be fine. The lower frequency black buzzers are available in a range of voltages and you would need to use a 6V buzzer is designed to work between 4 and 8 volts so would be fine with the 5V from the USB supply. Both types of buzzer take less than 30mA so would be OK.

    Asked by Chris Brennan on March 31, 2011 12:00 am
    Answered by the admin The USB power lead can be used to power an MP3 amplifier and it is something we have tried without a problem. Having said that the amplifier's performance is better at higher supply voltages. This is because it can only amplify to the maximum of the supply voltage before distorting. You may therefore also want to consider out 12V dc supply which works well. This can be found under the 'Power supplies and USB power' section.
