1 Overview
The MC9S08GW64 Tower MCU Module
(TWR-S08GW64) is a low-cost evaluation,
demonstration and development board. The
TWR-S08GW64 can operate stand-alone or as the main
control board in a Tower System with peripheral
modules.
The following list summarizes the features of the
TWR-S08GW64:
• Tower compatible microcontroller module
• MC9S08GW64 in an 80 LQFP package
• MC9S08JM60 based Open Source Debug
(OSBDM) circuit
• 3 user controlled LEDs
• 3 push buttons and two unpopulated headers for
user input
• 3 pin header for PCNT based sensors
• Potentiometer
