Can I use digispark attiny85?

[Andrjazz]

I have game boy advance sp and I want use LSDJ with my modular synthesizer.
I want build your project, if I use digispark attiny85 and use 5V from USB it's OK?

Hey! In principle it should work, just don’t connect Digidpark’s 5V with Vcc of your Gameboy. Let me know how it goes!
