1 Introduction
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.
2 Overview
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.

The signal assignment on the 2x20 pin connector is shown below. The convention of J1..J4
is replaced with P1…P4 to avoid confusion with the actual board reference.
Outer row connectors
Inner row connectors
Note : All signals are 3.3V COMS logic levels and is referred w.r.t. CC3100 IC. For e.g.
UART1_TX is an output from the CC3100.

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.

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.

The image above shows the connection of the Booster Pack to the FTDI Board. The
connectors should be aligned carefully considering that it does not have a polarity protection.
The pin-1 of the connectors are marked on the board using a DOT and these should be
aligned while mating.
Note : The mating and unmating force needed for these connectors may be large and may
end up breaking the boards. To prevent this caution should be restrained while unmating
these. Also , it is not recommended to mate the connectors all the way. About 3mm contact
length is good enough for the board as shown in the figure above.

4.3.1 Overview
The FTDI Debug Board 2.0A is designed to connect the Booster pack to a PC using USB
connection. This is used to update the firmware on the BP using the “SL_Prog” utility and
also in software development using “SL_Studio”.

4.3.3 Driver requirements
The FTDI Debug board requires the user to install the associated drivers on a PC. This
package is available as part of the SDK release and would be located at [InstallPath]\cc3100-sdk\tools\cc31xx_board_drivers\.
The install path is usually C:\ti\cc3100SDK

5 Connecting to a Launchpad
The CC3100 Booster pack can be directly connected to a compatible Launchpad using the
standard 2x20 pin connectors. The jumper settings needed for this connection is the same as
that needed for the FTDI Debug board as described in the previous section.
Please ensure that the Pin1 of the 2x20 pins are aligned correctly before mating. The mated
setup is as per the picture below. (Note the USB cable is connected to the Booster Pack
directly to power it only. For debugging, the USB cable on the Launchpad is also required)
FIGU RE 3 : B OOSTER PACK CONNE CTED TO TI VA LAUN CHP AD
5.1 Launchpad current limitation
Some of the launchpads including the MSP430FRAM launchpads do not provide enough
current to power the CC3100 booster pack. The booster pack can consume upto 400mA
peak from the 3.3V and hence it may be needed to power is separately.
For this a USB connector is provided on the Booster Pack to provide the 3.3V separately.
The power supply jumpers shall be configured as below when the power is supplied from the
on-board USB connector.

Important : Since there are two power sources in this setup it is important to follow the power-up
sequence.
Note : Always power the Booster Pack before powering the Launchpad.

5.2 Connecting to an experimenter’s board.
The Boosterpack could be connected to an experimenters board like the MSP430 FRAM
experimenter’s board using an EM Adapter board.
The EM adapter board converts the EM connectors to the standard 2x20 pin connectors of
the booster pack headers.
The stacked setup is as shown below. Ensure that the connectors are oriented correctly
before powering up the board.
