1.1 Introduction

Created for the Internet of Things (IoT), the SimpleLink Wi-Fi 6 and Bluetooth Low Energy CC3501E and CC3551E devices are single-chip microcontrollers (MCU) with built-in Wi-Fi® connectivity for the LaunchPad ecosystem, which integrates a high-performance Arm Cortex -M33 MCU and lets customers develop an entire application with one device.

No prior Wi-Fi experience is required for fast development with the CC35xxE devices to quickly enable Wi-Fi and Bluetooth Low Energy using it's high performance CP and robust security features. The CC35xxE LaunchPad kit, referred to by the part number, LP-EM-CC35X1, is a low-cost evaluation platform for Arm Cortex -M33-based MCUs. The LaunchPad design highlights the CC35xxE Internet-on-a chip design and Wi-Fi capabilities. By default the CC3551ENJARSHR is populated on the LP-EM-CC35X1, however the board and accompanying software is designed to support the CC3500E, CC3501E, CC3550E, and CC3551E.

The CC35xxE LaunchPad also features temperature and accelerometer sensors, programmable user buttons, RGB LED for custom applications, and easy connection to emulation boards for debugging. The stackable headers of the CC35xxE LaunchPad interface demonstrate the ease 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.

This evaluation module is specifically designed for development with the Eclipse-based Code Composer Studio™ (CCS) from Texas Instruments. More information about the LaunchPad, the supported BoosterPack modules, and the available resources can be found at the LaunchPad portal from TI.
