Hi All,
I'm looking for part suggestions for a 4-channel PWM I2C part for driving indicator LEDs. I'm currently considering thse PCA9685 and while within budget, it seems excessive to use a chip capable of driving 16 channels, when I only really need 4. Open to any suggestions and/or feedback. Using the PWM for dynamic brightness control of the indicator LEDs so that it doesn't blind people at 3am and for general adjust-ability. Using standard 5MM Red, Yellow, Green, Blue LEDs.
Goal with part choice is to reduce BOM if possible.
Cheers.
