Id love to try this on my two viparspectra such a cool idea!I finally got my boards! I assembled and tested a few tonight and it's looking good. Hopefully, I'll have some time to hang the viparspectra lights tomorrow.
Here's a couple of boards assembled. They have white and blue channel output (CH1 and CH2). These boards also support daisy chaining, so I can chain 2 pwm signals to multiple lights.
Here's a preview of testing the boards. I'm excited to get them installed soon!
