What is LaunchPad? LaunchPad is an easy-to-use development tool intended for beginners and experienced users alike for creating microcontroller-based applications. At $4.30, the LaunchPad offers everything you need to get started with your projects.
The LaunchPad development kit is a part of the MSP430 Value Line series. LaunchPad has an integrated DIP target socket that supports up to 20 pins, allowing MSP430 Value Line devices to be dropped into the LaunchPad board. Also, an on-board flash emulation tool allows direct interface to a PC for easy programming, debugging, and evaluation. Included are free and downloadable software development environments for writing and debugging software. LaunchPad can be used to create interactive solutions thanks to its on-board push buttons, LEDs, and extra input/output pins for easy integration of external devices.
Why LaunchPad? The LaunchPad is an easy-to-use, affordable, and scalable introduction to the world of microcontrollers and the MSP430 family.
Easy-to-use – LaunchPad includes all of the hardware and software needed to get started. Open source projects and code examples help users get up and running quickly.
Affordable – For $4.30, the LaunchPad includes a development board, 2 programmable MSP430 microcontrollers, mini-USB cable, PCB connectors for expandability, external crystal for increased clock accuracy, and free & downloadable software integrated development environments (IDEs) – everything you need to get started today.
Scalable – The LaunchPad is a simple introduction to the MSP430 microcontroller family. As application requirements change, programs developed on the LaunchPad can be migrated to higher end MSP430 devices.
