CC3235MODSF LaunchPad™ Development Kit (LAUNCHCC3235MOD)
1 Introduction
1.1 CC3235MODSF LaunchPad™
Created for the Internet of Things (IoT), the SimpleLink CC3235MODx is a wireless module with built-in
Dual-Band Wi-Fi connectivity for the LaunchPad ecosystem, which integrates a high-performance Arm
®
Cortex
®
-M4 MCU and lets customers develop an entire application with one device. With on-chip Wi-Fi,
Internet, and robust security protocols, no prior Wi-Fi experience is required for fast development.
The CC3235MODSF LaunchPad, referred to by its part number LAUNCHCC3235MOD, is a low-cost
evaluation platform for Arm
®
Cortex
®
-M4-based MCUs. The LaunchPad design highlights the
CC3235MODSF Internet-on-a chip solution and Dual-Band Wi-Fi capabilities. The CC3235MODSF
LaunchPad also features temperature and accelerometer sensors, programmable user buttons, an RGB
LED for custom applications, and onboard emulation for debugging. The stackable headers of the
CC3235MODSF LaunchPad XL interface demonstrate how easy it is to expand the functionality of the
LaunchPad when interfacing with other peripherals on many existing BoosterPack add-on boards, such as
graphical displays, audio codecs, antenna selection, environmental sensing, and more. Figure 1 shows
the CC3235MOD LaunchPad.
Multiple development environment tools are also available, including TI’s Eclipse-based Code Composer
Studio™ (CCS) integrated development environment (IDE) and IAR Embedded Workbench
®
. More
information about the LaunchPad, the supported BoosterPack modules, and the available resources can
be found at TI’s LaunchPad portal.
NOTE: The maximum RF power transmitted in each WLAN 2.4 GHz band is 19 dBm (EIRP power).
The maximum RF power transmitted in each WLAN 5 GHz band is 18.8 dBm (EIRP power).
NOTE: The antennas used for this transmitter must be installed to provide a separation distance of
at least 20 cm from all persons, and must not be colocated or operating in conjunction with
any other antenna or transmitter.
