2.3.1.1 Low Current Measurement (LPDS)

To measure the current draw of the CC3351 device for both power supplies (3.3V or 1.8V), a jumper labeled J16 (for 3.3V supply) and a jumper labeled J15 (for 1.8V supply) is provided on the board. By removing J16, users can place an ammeter into this path to observe the current on the 3.3V supply. The same process can be used for observing the current on the 1.8V supply with J15. TI recommends this method for measuring the LPDS.
