3 Hardware Features
This section provides more details about the features and functionality of the TWR‐LCD.
3.1 Power Supply
The TWR‐LCD can be powered as a standalone device from the Mini‐B USB connector. The TWR‐LCD
can also be powered from a source in an assembled Tower System via the 5.0V supply on the TWR‐
ELEV Side Expansion Port. When attached to a Tower Elevator board, it is required that the board be
externally powered from the Elevator board; additionally the USB connector on the TWR‐LCD can still
be used to communicate over USB to the on‐board MCF51JM MCU. On‐board power regulation will
provide the necessary core voltage (3.3V) and backlight driver voltage (15.5V).
