8 DMMEGAA.Net User Guide CHAPTER. DMMEGAA.Net HARDWARE DEVELOPMENT BOARD INTRODUCTION This content provides a more detailed description of the hardware features of the DMMEGAA.Net Development Board. HARDWARE FEATURES The key features of the DMMEGAA.Net are listed below. They are presented in the order given in DMMEGAA.Net Board Functionality and Features, (see Figure ). PROCESSOR SUPPORT The DMMEGAA.Net board has been designed to accommodate both TQFP pin for ATMega device at U. The microcontroller is an ATMega, running at either MHz OSCILLATOR OPTION: The installed microcontroller has two separate oscillator circuits connected. The main oscillator uses a MHz crystal. Using a. khz (watch type) crystal functions as the DS0 oscillator and serves as the source for the RTC oscillator. A 0 MHz crystal functions as the RTL09AS Ethernet Controller on Board. POWER SUPPLY There are two ways to supply power to the DMMEGAA.Net An unregulated AC/DC supply of 9V to V (preferably 9 V) supplied to J. For default functionality, a power supply with a current capability of 0 ma is sufficient. Since the board can serve as a modular development platform that can connect to multiple expansion boards, voltage regulators with a maximum current capability of A are used. Because the regulators do not have heat sinks, long term operation at such loads is not recommended. FIGTURE : ADAPTOR POWER JACK One green LED is provided to show when the DMMEGAA.Net board is powered up. The power on LED indicates the presence of.
