Type Description
PWR 1.8V–3.3V supply for BT. Must
be directly connected to
PMU_VDDIO and VDDIO on
the PCB.
PWR 1.8V–3.3V supply for SDIO
pads.
PWR IO supply for RF switch control
pads (3.3V).
PWR HSIC is not supported. Connect
this pin to ground to minimize
leakage.
PWR HSIC is not supported. Connect
this pin to ground to minimize
leakage.
