Hardware Description

The IDM-L35 design uses a Stellaris® LM3S1958 microcontroller to handle display functions, 
touch-screen control, UART, and peripheral functions. Only a few additional ICs are necessary to 
complete the design. The entire circuit is built on a compact four-layer printed circuit board. All 
design files are provided on the RDK-IDM-L35 CD.
