Feature Request: Level shifter and switch off #9

I really like the simplicity / compactness of the board, but it would be great it it had these two features:

Lots of boards use relays to switch off the strip - but I guess a transistor / MOSFET could be used as an alternative?

BTW, I bought one of these from Amazon (B0C1W1XJS8). I was slightly surprised to receive a HIWTSI version - no AJK branding. But it is working well with my SK6812 RGBW 5v LED strip.

We have gone for hiwtsi and AJK on the latest boards. Hiwtsi is my son's.

Level shifter is a pain as we don't have a 5V as such, just whatever power is. So would cope when using USB, worth a thought, but if powered from the strip at 24V it would drive 24V.

Board power using a FET, again, good idea, but you have to think of the current. I guess that would only work when USB, and would mean we can't power from the strip (which we can now).

So tricky ones. Maybe with some links to select. But quickly becomes way less compact.

But thanks for feedback.
