The elevator modules provide the power regulation circuitry and structural integrity needed for all configurations of an assembled Tower System. The functional elevator has two expansion connectors on the backside for easy signal access and side-mounting a board. The TWR-S08LL64 includes the LL64 MCU card that fits into the tower driving a segment LCD, RS232 transceiver and buzzer, several buttons, and includes analog sources such as a light sensor, a potentiometer and a three axis accelerometer. For a complete list of all available Tower System modules and kits, please visit www.nxp.com/tower. A Quick Start Guide and labs are also included to get started easily. Application notes and support resources such as CodeWarrior for Microcontrollers as well as documentation of software projects on TWR DVD are available, including an application note that demonstrates how to migrate from LL16 to LL64.
