Shubham,

There is a jumper on the right side of the CC1350_LAUNCHXL labeled VSENSE. You may also notice the labels XDS110 Power & Extern Pwr adjacent.

You should be able to measure the current consumption in series across this jumper.

Shubham,

I also should point you to the CC1350 LaunchPad design files so you can view the design schematics.

Derrick: No, you can not measure the current over the Vsense jumper. The jumper is to give the on board level shifters the correct reference voltage. Also please move CC13xx harware related question over to e2e.ti.com/.../156

Shubham: To get the correct measurements, flash the LP, remove all jumpers except for the Vsense one and supply the board through a multimeter on the 3V3 connector close to the antenna.
