Introduction

Board overview

This board is designed to be used as a standalone development platform for application development using the CC3200

device. It can be also used in conjunction with compatible booster-packs to enhance the peripherals available in the

system. The board features on-board emulation using FTDI device and has an array of sensors for an out of the box

experience. This board can be directly connected to the PC using software development platforms including CCS and IAR.

1.1.2 Power selection

The board can be powered from the USB connector using the on-board LDO (3.3V) or using an external battery (2xAA). The

battery is connected to J24. There is built-in reverse polarity protection for the battery connector.

The selection between the battery and USB power is performed using the jumper J23.

J23(1-2) [Battery powered]

J23(2-3) [USB powered]

1.1.3 USB connections

The Launchpad features an USB connector labelled J25.

J25 is used to power the board and also for the JTAG emulation and UART ports. Currently only one UART port for the

flash programming is provided on the board. The board requires the installation of Stellaris ICDI Drivers to be installed for

proper operation. This is provided as part of the SDK release.

1.1.4 JTAGsignals

The JTAG lines are brought out on separate headers on the PCB. The jumpers are shorted to connect the CC3200 JTAG to

the ICDI device on-board. To use an external emulator, these jumpers have to be un-installed and the JTAG signals to be

connected on the jumpers below.

1.1.6 On-board sensors

There are two sensors on the board which are connected to the I2C bus. The sensors can be isolated from the I2C bus

using the jumpers J14 and J13. By default the pull-ups on the I2C are not enabled. To enable these install jumpers J7 and

J8.

The sensors available on the board are listed below with their address
