Add a led strip to arms- help

Posted by Paolo on March 2, 2012 at 5:07am

Hello

Please i need help about this argument. I've got , or better i will have (depends of the shipping...) the APM2. I'd like to put 4 led strip, about 3 or 6 led each, one for arms like thiese one:

3690917382?profile=original

3690917462?profile=original

These led strip have a forward tension of 12v and resistor already included. Can i connect it in any APM2 pin and how? And please anyone to learn me how to manage the led with eg. a radio switch?

Ty

    Connect direct to outer pins of balance tap of 3S LiPo

    First of all, no, you cannot drive those directly from the APM2 pins.  They are rated at 5V and only 40mA.  Not nearly high enough.  You must use a transistor, MOSFET, etc, driven by the APM2 to switch on external power.

    Here's some good reading material, but this does not work yet for APM2:
