2.3.1.1 Low Current Measurement (LPDS)

To measure the current draw of the CC3301 device for both power supplies (3.3 V or 1.8 V), a jumper labeled J16 (for 3.3 V supply) and a jumper labeled J15 (for 1.8 V supply) is provided on the board. By removing J16, users can place an ammeter into this path to observe the current on the 3.3 V supply. The same process can be used for observing the current on the 1.8 V supply with J15. TI recommends this method for measuring the LPDS.
