Hi,
I'm currently working on a product with 32 one color & 40 bi color leds (these). I'm using an arm32 microcontroller, which uses 3.3v. As 3.3v are too little for running this many leds (the brightness would be too low), I plan to use a led driver.
I thought about using multiple tlc5925 or tlc5926. Do you think it would be good choice? However I'm a bit confused about the right LED voltage and the r-ext resistor.
I have alongside the 3.3v of my microcontroller 5v and 12v available on my board.
Thanks!
