Adafruit_TLC5947 for laser diodes

by unununium on Fri Oct 04, 2019 10:52 am

Hello,

I was hoping to use this board to fade small 3v-5v laser diodes. Is that possible? Was hoping to use 9 lasers, each around 150 mA at full brightness.

Yes, it can fade LED lasers. But the TLC5947 can do up to 30mA max. https://cdn-shop.adafruit.com/datasheets/tlc5947.pdf

Thank you - is that per channel, or across the whole board?

That is 30mA per channel.
