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.

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 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.

The signal assignment on the 2x20 pin connector is shown in Figure 3. The convention of J1..J4 is

replaced with P1…P4 to avoid confusion with the actual board reference.

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.
