I don’t suppose it would be safe to operate Unicorn Hat HD (but not the Raspberry Pi / Feather / etc.) at slightly _higher_ than 5V, to make the LED’s brighter?

I’m [projecting the light from my Unicorn Hat HD thru an Ektanar 102 mm lens onto a screen](https://forums.pimoroni.com/t/led-array-projector/15658/1). But as LED tech improves and the other Christmas lights in my holiday display get brighter, the projection is getting harder to make out in the cacophony.

P.S. Future readers may be interested to know that a pinout is currently available here: [Unicorn HAT HD at Raspberry Pi GPIO Pinout](https://pinout.xyz/pinout/unicorn_hat_hd)
