Trying to run this board with an STM32f429i-disco dev board. I know your page shows voltage input pin requiring 3.3 V. The "3v" output on my STm32 dev board measures at 2.94V. Is that too low to power the audio board?
I see there is a 5V pin on your board. Is that operational as an alternative voltage input source?

Thanks
Leor
