1Introduction
This document provides a quick start guide on using the CC3100 Booster Pack Rev 2.0B .
This is not applicable to other revisions of the board.
2Overview
The CC3100 Booster Pack is a board designed to interface with the TI standard Launchpad
including the Tiva-C series and the MSP430 value line launchpads. In addition to the
launchpads, there is support available to mate the board with a FTDI Debug board to
interface directly to a PC host using USB cable. A picture of the board is presented below
with the main components marked.

J6
Power selection
Choose the power supply from the
Lauchpad or the on-board USB.
J6 (1-2) power from MCU Launchpad
J6 (2-3) power from on-board USB using
3.3V LDO
J24
Current
measurement
Voltage is measured across the 0.1 Ohm
resistor using a voltmeter.
Can be used for IDLE and Active
currents.
For Hibernate currents, remove R42 and
connect a ammeter across J24. Range
(< 100uA)

Open : GPIO_12 is pulled to GND using
33K resistor.

RESET
Closed : Routes the RESET signal from
the MCU Launchpad to the CC3100.
Open : The RESET is cut off from the
MCU. (Used with MSP430 boards where
RESET line is muxed with TEST)

Note : This LED can glow if the board is
powered from any of the GPIO being
high, and the Vcc is un-connected. This
is not a valid state and should be
avoided.
3.6 Conducted testing
The board is by default configured for radiated measurement using the on-board chip
antenna. For conducted testing in the lab the following changes needs to be done on the
board.

Radiated test
using antenna
C4 = DNP
C2 = 10pF
Note : The 10pF capacitor used should be of RF grade with high-Q to reduce the overall
loss. Otherwise a 0 Ohm resistor can also be used for this.
3.7 Current measurement
The board provides a jumper connected to a 0.1 Ohm resistor for current measurement. The
measurement is made by using a voltmeter across the jumper and multiplying the value
obtained in mV by 10 to get the current in mA. The current measurement jumper is J24 as
shown in Figure 1.
Note : The measurement may have up to 10% error due to resistor variation and contact
resistance due to reflow soldering.
