Getting Started
1.1 Introduction
The CC3200MOD LaunchPad is an easy-to-use evaluation module for the CC3200 WIFI microcontroller Module. It contains everything needed to start developing on a low-power Arm Cortex M4F MCU, inc lu din g onboard emulation for programming and debugging as well as onboard buttons and LEDs for quick integration of a simple user interface.
The CC3200 supports growing applications with increased CPU speed, memory, and 32­bit performance.
Rapid prototyping is a snap thanks to the 40-pin headers and a wide variety of BoosterPack plug-in modules that enable technologies such as , graphical displays, Audio codec, Antenna diversity, environmental sensing, and much more.

Headers for current measurement and external JTAG connection.
Bus powered device with no external power required for WIFI.
Long range transmission with highly optimized antenna (200m Typical in open air with a
6dBi antenna AP)
Can be powered with external 2xAA or 2xAAA alkaline batteries working down to 2.3V typ.
2.2.1 Power connections
The board can be powered by using the on-board micro USB connector. An on-board LDO provides 3.3V for the CC3200 and the rest of the board to operate. This supply can be isolated from the LDO using the jumpers on the board.

Can be used to power the board from an external 2XAA battery pack. It has in-built reverse voltage protection to prevent the battery from being plugged
2.2.2 2x20 pin connector assignment
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.

The signal mappings are as per the table above. All the signals are referred by the pin-no in the SDK and the table above shows the default mappings. Note that some of the pins are repeated across the connector. For e.g. pin 62 is available on P1 and P4, but only P1 is connected by default. The signal on P4 is marked with a *(star) to signify that is not connected by default. It can be routed to the pin by using a 0 Ohm resistor in the path. Please refer to the schematics and placement diagram for the exact resistor placement.
2.3 Power
TI Confidential – Strictly Private 7
The Launchpad is designed to work from the USB provided power supply as it enumerates as a bus-powered device. Care has been taken in the design to ensure that the board does not violate the in-rush limits of the USB bus. The board can also be powered by an external 2xAA or 2xAAA battery which is connected on J20.
