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.

Question:

Is this item able to supply sufficient output for initial testing of completed Mono MP3 Amplifier kits?

Answers:

  • Posted by Matt Macleod on Friday, 11 April 2014
    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.

Question:

Hi there, would a 3.v bulb lamp in a holder work off this USB lead?

Answers:

  • Posted by Matt Macleod on Friday, 11 April 2014
    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.

    Hi, yes that would work fine. There is an example of how to do it on this page http://www.kitronik.co.uk/resources/electronic-tutorials/1w-star-led-datasheet/

Question:

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.

Answers:

  • Posted by Geoff Hampson on Friday, 13 July 2012
    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.
