ABSTRACT
The AM243x LaunchPad
™
development kit is a simple and inexpensive hardware evaluation module (EVM) for
the Texas Intruments Sitara
™
AM243x series of microcontrollers (MCUs). This EVM provides an easy way to
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.
