Table 1. Push Buttons
Comments
This is used as an input for the OOB demo.
The use of this pin is optional. It resets the device to a known state.
This boots the device to the bootloader mode for flashing the firmware over a universal asynchronous
receiver/transmitter (UART).
Table 2. LEDs
Usage Comments
PWR ON, when the 3.3 V power is provided to the board.
indication
nRESET This LED indicates the state of the nRESET pin. If this LED is glowing, the device is functional.
nHIB This LED indicates the state of the nHIB pin. When the LED is OFF, the device is in hibernate
state.

Comments
For powering the BoosterPack when connected with a LaunchPad. This is mandatory when using "Z"
devices (for example, CC3100HZ).
Choose the power supply from the Lauchpad or the on-board USB.
J8 (1-2) power from MCU LaunchPad
J8 (2-3) power from on-board USB using 3.3 V LDO
For Hibernate and LPDS currents, connect an ammeter across J26 : Range (< 500 µA)
For Active current, mount a 0.1 Ω resistor on R42 and measure the voltage across the 0.1 Ω resistor
using a voltmeter (range (< 50 mV peak-peak)).
Closed: nHIB is pulled to VCC using 10K
Open: nHIB pin is floating and is driven from EMUBOOST. (On Rev 3.3 and earlier, this was used to
control GPIO_12)
2x10 pins each connected to the LaunchPad.
Murata connector (MM8030-2610) for production line tests.
U.FL connector for conducted testing in the lab.
