-So here comes PiSugar2 Pro, a special PiSugar version for Raspberry Pi 2/3A/3B/3B+/4B. It's designed with the same architecture as PiSugar2, with a bigger size and some additional features.

 ## Charging (Same as PiSugar2)
 
 Please use PiSugar's type-c or micro USB port for charging. If you use pi0's USB port it won't charge PiSugar, and PiSugar will turn off automatically since the external power is enough for pi0 to run.
