NanoBiscotte v4 RGB Issue (power extender or wiring?)
« on: June 26, 2020, 10:33:28 AM »
I have an NBv4 RGB wired up and everything is working properly except the blue LED during normal running; it is firing off during FoC events though. Below is a current wiring picture (please don't judge my soldering to much, this it my first time soldering) along with a wiring diagram. As you can see, I have the blue wire coming from the L3 pad over the top and soldered to the "R" for the power extender, then a negative wire (White) to the negative pad (joining with a switch and recharge port negative), followed finally by a negative wire (Blue) coming from the blue LED negative. Also, as you can see from the wiring diagram and pictures, the white/blue lines from the chassis on pads 2 and 5 respectively, are the 2 lines from the joined switches.
The saber itself will activate, swing, FoC, etc, the only issue is during normal operation the blue LED isnt lit; FoC it will light.

Wiring:

Diagram:


Notes: Since the board is upside down, Ill list whats on each pad
Pad 1 (+): Recharge port positive, single positive line to R,G,B LEDs
Pad 2 (-): Line (-) from 2 switches (joined together), Negative from recharge port, Negative from power extender
Pad 3 (L1): Negative from red LED
Pad 4 (L2): Negative from green LED
Pad 5: (Activation): Line (+) from 2 switches
Pad 6 (Speaker): Speaker line 1
Pad 7 (Speaker): Speaker line 2
Underside (L3): Wire to power extender "R"
Power Extender (bottom -): Negative from blue LED

Did I mess something up or miss something? The fact its mostly operating normally, especially during FoC makes me think it's a wiring issue with the power extender, but everything seems right.

your color configuration is probably not set correctly, adjust the drive of your color config for FoC and blade, to reflect your wiring

Actually, youre right, what an oversight by me. I forgot my first sound bank was lime green (below), while 2 was ice blue and 3 was purple. Once I swapped to those 2, it was running as expected. Thanks for the reply, all seems well now.

Side note, is there a way to test the current battery voltage through the recharge port? How can you tell when its time to recharge it (besides it dying)?

by inserting a male DC jack in the recharge port, you reach the battery. You can measure the voltage there with a voltmeter, or build a PLI unit. For this, you'll find some cheap voltmeter (LED, OLED display) modules that can be your portable voltmeter (cell discharged is below 3.5V usually). I think the custom saber shop might have a LED PLI as well giving a cell gauge out of 7 or 10 led segments
