    Default Video: Flash on Clash using a PEx

    Responding to poplular demand, here are some helpful tips when installing your Pex with a Nano Biscotte 2.0 (or older Petite Croutons).

    Sweet. Now I can reference this video and the other one when I begin my next projects. Thanks!

    Great vid Rob. I have a few questions, is a resistor not needed on the pex for the foc die? I noticed you didnt wire one up. If a resistor isnt needed, whats the reason for a smd resistor accommodation? What possible scenarios where a resistor is needed on the pex for the foc die?

    Thanks for any input

    A resistor *might* be needed. It depends on the battery pack voltage and the particular LED you are using. Most of the time, you will need a resistor. Occasionally you'll have battery/LED combinations that allow you to get by without one.
    We all have to start somewhere. The journey is all the more impressive by our humble beginnings.

    Correct.

    The PEx was devoloped back when no Plecter boards ran with a single 3.6 volt battery. I've used them on the old Petite Crouton where your battery voltage is 7.4 and your white LED is 3.2 v or something like that. In those cases I used a resistor. Nowadays with the Nano Biscotte, I would not use a resistor on the FoC PEx unless the FoC LED was a red/orange/amber (2.1 volts approx).

    Thanks for the response guys. So just to confirm, the tri crees like http://www.thecustomsabershop.com/Gr...ova-P1015.aspx are safe to use with no resistor on the white LED while using a NBV2, correct?

    I personally would put a small resistor on it, just to be safe, but that's just me. I'd rather spend a buck for a small resistor, than $20 to replace a Tri-LED.

    Correct.
    But as FJK says - using a resister is safe-er, especially if you are new and the risk of wiring it incorrectly is there, or if you plan to program your FoC to be on for long periods of time.

    Use this if you wish, until Tim gets the .5 Ohm in stock:
