AM243x LaunchPad™ Development Kit User's Guide
The AM243x LaunchPad
the Texas Intruments Sitara
start developing on the AM243x MCUs with on-board emulation for programming and debugging as well as
buttons and LEDs for a simple user interface. The LaunchPad also features two independent BoosterPack XL
expansion connectors, on-board Controller Area Network (CAN) transciever, two RJ45 Ethernet ports, and an
on-board XDS110 debug probe.
