Measure the CC3100 Current Drawn

2.5.1

Low Current Measurement (Hibernate and LPDS)

To measure the current drawn from the CC3100 device, a jumper is provided on the board labeled J6. By

removing this jumper, the user can place an ammeter into this path and observe the current. This method

is recommended for measuring LPDS and hibernate currents that are just a few 10s of micro amps. The

jumper is removed and an ammeter is added in series to measure the hibernate and LPDS currents (see

Figure

9).
