Reference Usage Comments

SW1 OOB Demo This is used as an input for the OOB demo.

SW2 RESET The use of this pin is optional. It resets the device to a known state.

SW3 nHIB This boots the device to the bootloader mode for flashing the firmware over a universal asynchronous

receiver/transmitter (UART).

Reference Colour Usage Comments

D5 RED PWR ON, when the 3.3 V power is provided to the board.

indication

D1 Yellow nRESET This LED indicates the state of the nRESET pin. If this LED is glowing, the device is functional.

D6 Green nHIB This LED indicates the state of the nHIB pin. When the LED is OFF, the device is in hibernate

state.

2.3.2 Jumper Settings

Table 3. Jumper Settings

Reference Usage Comments

J7 USB connector For powering the BoosterPack when connected with a LaunchPad. This is mandatory when using “Z”

devices (for example, CC3100HZ).

J8 Power selection 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

J6 Current For Hibernate and LPDS currents, connect an ammeter across J26 : Range (< 500 µA)

measurement 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)).

J5 Reserved 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)

J10, J9 BoosterPack 2x10 pins each connected to the LaunchPad.
