Thread: NBV3 Schematic check please

  1. #1

    Default NBV3 Schematic check please

    Hey guys! I am in the process of my first build and I have been reading and reading trying to understand how all this works for when I get one of these boards in my hands. I am planning my build with the Tri-XP-E2 in RB/RB/W Parallel with W being FoC. I made this schematic with the fact in mind that this card has an on-board PEx. Ive read the new manual online a few times, hope I am not missing anything. Just curious if you can take a look at this and let me know if my plans are sound...no pun intended! lol I have never made a schematic so forgive me if its wonky. Your thoughts are welcomed and appreciated!

    That looks correct to me.

    Got a question? Start Here. Have you tried the Thread Index yet? Most questions can be answered there.

    Awesome! Thank you for taking a moment to look it over! I am sure these get put on here over and over and it must get old having to figure out everyones stuff so i appreciate it! I wont touch this build until I understand every aspect so I had to manually make my own schematic to test and grow my understanding. Thanks again!

    I haven't read the new V3 manual yet so I haven't looked at how the onboard Pex is wired, but the rest looks good.

    Nice diagram, too. Easy to read/follow. Good work.

    When is the v3 supposed to come out?

    It *should* be out by the end of the month or so.

    Thanks Miraluka! I am trying my best to put the work in and not be that noob that just wants everything done for him! Everyone has been great though for the few silly questions I have had! I am actually having so much fun planning this build and learning!

    I would appreciate it if someone could check my calculations for the power resistors for a NBv3 and Tri-CREE LED combination! I used the guidance in the NBv3 manual and am assuming the same wiring set-up as Count Voodoo's diagram.

    LEDs: two royal blue with a forward voltage of 3.41v @1000mA and one white with a forward voltage of 3.15v @1000mA.
    Battery: 18650 (?)

    Calculations:
    royal blue LED resistor = (3.7 - 3.41) / 1.0A = 0.29 ohms
    resistor wattage = (3.7 - 3.41) * 1.0A = 0.29 watts

    white LED resistor = (3.7 - 3.15) / 1.0A = 0.549 ohms
    resistor wattage = (3.7 - 3.15) * 1.0A = 0.55 watts

    -thanks, guys!

    Your calculations for the resistors is right, but your wattage calculation looks wrong to me...the formula is: P <Watts> = R * I^2 Your numbers are: P=0.29*1^2 which equals out to 0.29 watts...you'd need a 1/2 watt resistor for those. The white works out to be a 0.549 watts, so you'd likely need to round up to a 1 watt resistor for that.

    Thanks for the review....very much appreciated.

    I'll re-check the NBv3 manual for the wattage calculation, sounds like it may be incorrect.
