A1AndA0bComparison of functional differences

 

A1	A0b
sampling：Operational amplifier sampling	Current sampling chip sampling
Unidirectional current detection	Bidirectional current detection
Zero point calibration is not required for power on，Plug and play	No load on each power on，Calibration required0spot
MCUInternal temperature sensor	NTCTemperature sensor

 

summary：

A0bThe performance is a little better，But it is not convenient to use（A0bDon't plug in the mobile phone and other loads every time you power on，Because it is bidirectional detection，The current zero point needs to be calibrated every time）

A1Calibration is not required，Plug and play
