TI EK-TM4C1294XL LaunchPad



This guide will walk through how to connect the Texas Instruments EK-TM4C1294XL Micro-controller and port the Out-Of-Box experience to Murano. The EK-TM4C can be purchased via the Texas Instruments website. While this process does require extra development work to update the code, this easy-to-follow guide does not require the user to have any coding/development experience.

Legacy Development Kit Support Information

TI partnered with Exosite on a number of development kits from 2013 to 2018 where Exosite would provide free community accounts for use with the development kits, such as the EK-TM4C1294XL and EK-TM4C129EXL Crypto Launchpads, CC3200-LAUNCHXL Wi-Fi Connected Launchpad, and MSP430 FRAM + CC3000 Wi-Fi Kit with SmartConfig™. In 2020, Exosite ended the community devlopment kit support. Free accounts are no longer available. Many of Exosite's customers have used Texas Instrument silicon in their connected products. Exosite's platform is well suited for TI's silicon when used in IoT and condition monitoring applications, please contact sales for more information about your project.
