Actually, I have a hikey lemaker board.

So i want to connect hikey board with PN7150. But hikey board just supports 1.8v supply( doesn't support 3.3v ).

When i read user manual for PN7150, PN7150 needs 3.3v for VBAT power supply.

If i connect 1.8v on hikey board to VBAT(PVDD) of PN7150, what happen? what is phenomenon??

(  does it just affect RF performance??)

Should I use the Level Shifter( 1.8v->3.3v) ??
