Megadonkey with Mega128 and 128x64 LCD

(click images to enlarge -- user supplied mouse not included)

	16 MHz ATMega128 microcontroller (128K Program Flash, 4K RAM, 4K EEPROM)
	3.1" Transflective Bitmapped graphics LCD (128x64) with LED backlight
	Supports standard serial mouse OR our DonkeyBall Trackball interface with full software support making it easy to add buttons, slide controls, check boxes and more to your applications

	Extensive software library including graphics, communications, menu functions and more -- all backed by demo programs making it easy to see how they are used
	Two RS-232 (Male = Data Terminal Equipment Interface) ports supported by hardware UARTs onboard the microcontroller and a Texas Instruments MAX213 RS-232 receiver/driver.
	Serial Communication jumpers allowing allocation of any combination of signals to RS-232 Driver & Receiver for each port, allowing up to 8 processor I/O pins to be freed for other uses if not needed for serial IO
	ISP Connector for connection to serial programmer, e.g. Atmel STK-500
	I2C Connector (two 5x1 pin headers available) for connection to I2C devices
	JTAG Connector for connection to JTAG debugger/programmer
	39 Pin (20 x 2 0.100" spaced male pins) header for interfacing to a wide variety of devices, this connector is physically compatible with cables used for old IDE harddrives (not pinout compatible) which is handy for connecting your donkey to project boards where you want more space than is offered by the prototyping area
	4 Low Power High Efficiency LEDs (software PWM intensity control available)
	Mini 8-Ohm speaker supports variable pitch, and duration tone generation
	Prototyping Area with lands for 8 pin SOIC and space available for up to a 40 pin DIP or several smaller devices
	Power Input (via 2.1 mm center + jack) 7 to 24 VDC with reverse polarity protection provided to prevent frying your donkey if you accidentally reverse the polarity
