Module BoosterPack Hardware

1 Introduction

1.1 CC3100 Module BoosterPack (CC3100MODBOOST)

Add Wi-Fi to any low-cost, low-power microcontroller (MCU) for Internet of Things (IoT) applications using

the CC3100 Module BoosterPack (CC3100MODBOOST), which hosts the CC3100 module

(CC3100MOD). The CC3100MOD is FCC, IC, CE, and Wi-Fi certified. It integrates all protocols for Wi-Fi

and Internet, greatly minimizing host MCU software requirements. With built-in security protocols, the

CC3100MOD solution provides a robust and simple security experience. The CC3100MOD integrates the

serial flash, RF filter, crystal, and all required passive components.

This document explains the various configurations, usage, and versatility of the CC3100MODBOOST.

First, it can be connected to a TI MCU LaunchPad (provided examples for MSPEXP430F5529LP).

Second, it can be plugged into a CC31XXEMUBOOST board and connected to a PC for MCU emulation.

The CC3100MODBOOST firmware updates requires either the CC31XXEMUBOOST board, or the micro-

controller over-the-air(OTA) software and access to a server. Finally, the exposed signals on the 20 pin

connector provide an interface to an additional microcontroller or platforms beyond TI's LaunchPads. The

CC3100MODBOOST is a complete platform solution, including various tools and software, sample

applications, user and programming guides, reference designs, and the TI E2E™ support community. Visit

the CC3100 Wiki page for design resources and example projects

The signal assignment on the 2×20 pin connector is shown in Figure 4. 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 400-mA logic levels, and are referred w.r.t. CC3100MOD IC.

For example, UART1_TX is an output from the CC3100MOD. For the SPI lines, the

CC3100MOD 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

this case, the USB connector on the CC3100MODBOOST can be used to aid the peak current. The use of

Schottky diodes ensure that the load sharing occurs between the USB connectors on the LaunchPad and

the BoosterPack without any board modifications.

The 3.3-V power can also be sourced from the LaunchPad, or from the 3.3-V LDO on the board by using

jumper J8. If the LaunchPad is not able to source the 3.3 V up to 350 mA, configure the J8 to work from

the on-board LDO.

2.4.1 Power From the LaunchPad or CC3100EMUBOOST

The most common scenario is to power the CC3100MODBOOST from the connected LaunchPad. In this

case, the LaunchPad provides 3.3 V to the BoosterPack for its operation (see Figure 5). In addition to the

3.3 V, some LaunchPads provide a 5 V from the USB (see Figure 6), used to drive a 3.3-V LDO on the

BoosterPack. If the LaunchPad is not able to provide the 5 V (for example, the LaunchPad with only 20

pins), then the USB connector on the CC3100MODBOOST should be used to provide the LDO input as

shown below.

2.4.2 On-Board LDO Power Supply

On some LaunchPads, the 3.3 V is not capable of sourcing the 350-mA peak current needed for the

CC3100MODBOOST. In this case, the on-board 3.3-V LDO can be used (see Figure 7). This LDO is

sourced from the USB connector on the CC3100MODBOOST and the LaunchPad in a shared load

manner.

2.5 Measure the CC3100 Current Drawn

2.5.1 Low Current Measurement (Hibernate and LPDS)

To measure the current drawn from the CC3100 device, a jumper is provided on the board labeled J6. By

removing this jumper, the user can place an ammeter into this path and observe the current. This method

is recommended for measuring LPDS and hibernate currents that are just a few 10s of micro amps. The

jumper is removed and an ammeter is added in series to measure the hibernate and LPDS currents (see

Figure 9).
