I was wondering.
I want to create a battery operated configuration using the PiJuice HAT.
The problem I can foresee with this setup is that the HIFIBERRY AMP2 requires more power.
I was thinking to use some sort of Step-up transformer to take the power from the PiJuice HAT and power the HIFIBERRY AMP2 HAT/module.
But I am thinking now it perhaps by doing this I might not be creating a short between the Raspberry Pi + PiJuice HAT and the HIFIBERRY AMP2 through the GPIO headers.
Should I use instead a separate battery setup something that can offer the required power for the HIFIBERRY AMP2? this would be a shame because it would slightly increase the complexity of the setup.
Could you advise and point me to where I can get this information?
