Being able to do individual PWM is a small bonus and performs sufficiently at night. Still the main function of the board is to uniformly light up LEDs with the same color, which gives much higher brightness. That way 6+1 combinations of (R,G,B) can be used.
There seems to be some tint or something in the glass in Portland's terminal windows that's throwing off my exposure and white balance a little bit. N921DL is nearly thirty years old, delivered new to Delta in June 1988.

ON Semiconductor today introduced three new flexible synchronous pulse width modulation (PWM) controller devices – the NCP3020A, NCP3020B and NCP3011. Offering a wide input voltage range, from 4.7V to 28V, these devices enable the flexibility to be used with a variety of input sources in consumer electronic equipment such as set-top-boxes and LCD televisions, as well as industrial and computing applications including printers, scanners and telecom systems.
