1.3 Supply interfaces
1.3.1 Main supply inputs
JODY-W3 series modules are powered through the 3V3/VIO/1V8 pins. An integrated Buck converter
supplied from the 1V8 generates the core voltage to the embedded systems ASIC.
The current consumed through the VIO and 1V8, and 3V3 pins by JODY-W3 series modules can vary
by several orders of magnitude depending on the operation mode and state. Current consumption can
change from the high current consumption during Wi-Fi transmission at maximum RF power level in
connected-mode, to the low current consumption during low power idle-mode with the power saving
configuration enabled.
For a detailed description on the supply voltage requirements, see the JODY-W3 series data sheet [1].

Not implemented
Commented [MH10]: The chipset internal DC/DC is
powered from 1V8. 3V3 is mainly used for the
chipset internal PAs. Both, 1V8 and 3V3, change
the current consumption depending on the
operating mode.
