Last week two of these arrived at my doorstep. It’s the newly launched Texas Instruments Stellaris LaunchPad.
I pre-ordered directly from Ti a few months ago. https://estore.ti.com/Stellaris-LaunchPad.aspx
The Stellaris LM4F120 LaunchPad Evaluation Kit includes the following items:
- Stellaris LaunchPad Evaluation board (EK-LM4F120XL)
- USB Micro-B plug to USB-A plug cable
- ReadMe First quick-start guide
The Stellaris LM4F120 LaunchPad evaluation board offers these features:
- Stellaris LM4F120H5QR microcontroller
- USB Micro-B connector for device
- RGB user LED
- Two user switches (application/wake)
- Onboard Stellaris® In-Circuit Debug Interface (ICDI)
- Available I/O brought out to headers on a 0.1″ grid
- Switch-selectable power sources:
- ICDI
- USB device
- Reset switch
- Preloaded RGB quickstart application
- Supported by StellarisWare® software, including the USB library and the peripheral driver library
- Stellaris® LM4F120 LaunchPad BoosterPack XL interface, with stackable headers to expand the capabilities of the Stellaris® LaunchPad development platform
The EK-LM4F120XL works with StellarisWare, as well as several different software tool chains, including:
- Keil
- Sourcery CodeBench
- IAR Tools
- CodeComposer Studio
The LM4F120H5QR that the launchpad uses is an 80Mhz 32bit Arm Cortex M4 with floating point and 256KB Flash / 32KB SRAM / 2KB EEPROM. It also includes dual 12-bit ADC, 6×64-bit and 6-32-bit timers and many serial comms. (From the back of the box.)
