Looking at driving a cockpit LED strip off the GAD 27 PWM pin. From the docs, it can only sink up to 500mA and it seems the average RGBW LED used in strips out there pulls 20mA per color and 25mA per white.
At full brightness I'm looking at only being able to power 20 white LED's or 25 individual color LEDs, which seems a bit low considering the usual strip for sale is 60 LED/m with 144 LED/m being fairly common. This is for my dash eyebrow so about 1m long.
How are others doing this? Put a transistor in place to drive the power?
