Multi-channel FET board / RGB LED Driver

Other Hardware General Electronics

I have a 8 RGB LED strips that I would like to drive individually (12V), so that makes it 24 channels in total.

Does anyone know of any 12+ channel mosfet boards/LED drivers that won't break the bank?

Anything would do really, as long as it can power 12 or more 12V channels @1A

I've tried searching online, but found either boards for industrial application ($$), ones that can't push enough current or handle 12V

Worst case I'll make some simple design using TLC5940 or similar but I'd rather avoid it!

Thank you :slight_smile:

I stumbled upon a 24 channel DMX decoder

I assume this would be a suitable alternative!

I've used these BTS117 "Smart Low-Side Power Switches" before:

They can be driven direct from a 3V logic pin.

like this:

There's four RGB strips, with three BTS117 for each strip - so a total of 12 "channels"

Those strips are actually 24V
