The CC3235 SimpleLink™ LaunchPad™ Development Kit (LAUNCHXL-CC3235x) is a low-cost
evaluation platform for Arm
CC3235 Dual Band (2.4 GHz and 5 GHz) wireless MCU system on a chip. The CC3235 LaunchPad™ kit
also features temperature and accelerometer sensors, programmable user buttons, RGB LED for custom
applications, and onboard emulator for debugging. The stackable headers of the LAUNCHXL-CC3235x
demonstrate how easy it is to expand the functionality of the LaunchPad™ kit. BoosterPack™ Plug-in
Modules allow for interfacing with other peripherals such as graphical displays, audio codecs, antenna
selection, environmental sensing, and more.
The CC3235S and CC3235SF devices are part of the SimpleLink™ microcontroller (MCU) ecosystem
which consist of Wi-Fi
use development environment with a single core software development kit (SDK) and a rich tool set. A
one-time integration of the SimpleLink™ platform lets you add any combination of devices from the
portfolio into your design. The ultimate goal of the SimpleLink™ platform is to achieve 100% code reuse
when your design requirements change. For more information, visit www.ti.com/SimpleLink.
