Question:

Can this USB be used as the power source for the radio kit you supply? If so how can it be fitted

Answers:

    Yes, just use it instead of the PP3 clip. Red wire to the  '+' on the board, black wire to the '-'.

Question:

Could the USB lead be plugged into an iPad charger adapter to power the light from the mains rather than from the desk top USB port?

Answers:

    Hi, yes it can. Those ipod charger adaptors output 5V like most phone chargers so that is fine.

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.

  • Posted by Aaron Sturman on Monday, 11 November 2013
    Hi, yes that would work fine. There is an example of how to do it on this page https://www.kitronik.co.uk/resources/electronic-tutorials/1w-star-led-datasheet/
