CC3100 SimpleLink™ Wi-Fi®and IoT Solution
BoosterPack Hardware
1 Introduction
1.1 CC3100 BOOST
The CC3100 SimpleLink™ Wi-Fi®solution provides the flexibility to add Wi-Fi to any microcontroller
(MCU). This user guide explains the various configurations of the CC3100 hardware BoosterPack™. This
internet on a chip solution contains everything that you need to easily create IoT solutions – security, quick
connection, cloud support and more. The CC3100 BoosterPack can be used in several ways. First, it can
be connected to a TI MCU LaunchPad (software examples provided for MSP-EXP430F5529LP). Second,
it can be plugged into a CC31XXEMUBOOST1board and connected to a PC for MCU emulation. Finally, it
can be connected onto an adapter board (MCU-ADAPT), which allows customers to use CC3100BOOST
with additional platforms beyond TI LaunchPads.
This kit comes in three configurations:
• CC3100BOOST + CC31XXEMUBOOST + MSP-EXP430F5529LP – Able to run all software in SDK,
and develop on MSP430F5529 MCU.
• CC3100BOOST + CC31XXEMUBOOST – Used for any CC3100 development.
• CC3100BOOST – If extra CC3100 BoosterPacks are needed, and the user already has
CC31XXEMUBOOST.
NOTE: 1CC31XXEMUBOOST is an advanced emulation board that is required for flashing
CC3100BOOST, using the radio tool (Radio performance testing or putting into certification
modes), and for doing networking processing logs for advanced debug.
NOTE: The antennas used for this transmitter must be installed to provide a separation distance of
at least 20 cm from all people and must not be co-located or operate in conjunction with any
other antenna or transmitter.
NOTE: The pictures used in this document refer to Rev 3.x, but the contents also apply to Rev4.0
and higher unless otherwise stated. For the changes across the various revisions of board,
please refer to Section 5.3.

2.3 Connector and Jumper Descriptions
2.3.1 Push Buttons and LEDs
Table 1. Push Buttons
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).
Table 2. LEDs
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 Ωresistor on R42 and measure the voltage across the 0.1 Ωresistor
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.
header
J3 RF Test Murata connector (MM8030-2610) for production line tests.
J2 RF Test U.FL connector for conducted testing in the lab.

NOTE: All signals are 3.3 V CMOS 400mA logic levels and are referred w.r.t. CC3100 IC. For
example, UART1_TX is an output from the CC3100.
For the SPI lines, the CC3100 always acts like a slave.
2.4 Power
The board is designed to accept power from a connected LaunchPad or from the CC3100EMUBOOST
board. Some of the LaunchPads are not capable of sourcing the peak current requirements of Wi-Fi. In
such a case, the USB connector on the CC3100BOOST can be used to aid the peak current. The use of
Schottky diodes ensure that the load sharing happens between the USB connectors on the LaunchPad
and the BoosterPack without any board modifications.
Also the 3.3 V power can be sourced from the LaunchPad or from the 3.3 V LDO on the board. This is
done by using jumper J8. In the case where the LaunchPad is not able to source the 3.3 V up to 350mA,
then the J8 needs to be configured to work from the on-board LDO.
