Hello
I need help finding a mosfet board that uses N-mosfets and switches using a negative signal.
it's for RGB LED amplification, and i could use one form Ebay, if it wasn't for the fact that my controller uses voltage control (not PWM) to change the brightness of the channels (color), an i haven't been able to find a varaiable gain amplifier.
the only thing i could find in that regard was a VCA810 chip, but i'm not even sure it does what i'm asking, and i still need a PCB.
anyway, back to the mosfet board. this one i have would otherwise be perfect:
**broken link removed**
if it wasn't because it uses a positive signal to open the gate on the mosfet.
I hope you guys can help me.
