3.1.1.1 Measuring Current Consumption

These jumpers can also be used to measure the current consumption by placing current sense resistors on R10 for VBAT_CC and on R7 for VDD_1V8. Both these resistors are 0.10 Ω, 1/4 W. The VBAT_CC jumper can be used to to measure the voltage and power consumed by the CC256xC, including RF TX and RX while the VDD_IO jumper can be used to measure voltage and power consumed by the digital I/Os.
