Evaluation Kit Atmel ATMEGA1284P-XPLD
Evaluation board for Atmel megaAVR.
Detailed Description
It features an ATmega1284P and additional components demonstrating the features of the device.
The AVR Xplained kits are great platforms for early evaluation of the capabilities offered by the AVR microcontrollers. The MEGA-1284P Xplained contain one QTouch button sensor, three mechanical buttons, four LEDs, 3 analog sensors, a UART to USB bridge. The AVR Xplained expansion headers provide easy access to analog and digital I/O pins. The board is powered by the USB cable and equipped with the standard 10-pin JTAG header that connects to the full range of AVR debuggers.

The preprogrammed firmware in the ATmega1284P is set up with example code that allows the user to choose different sleep modes, and provides an example of how to use the light sensor to dim the four onboard LEDs. It also includes a boot loader (AVROSP) which allows the user to reprogram the ATmega1284P without using an external programmer.
The kit is powered via the USB connector, which presents two options for powering it: Either connect the kit to a PC through a USB cable or to a 5V USB power supply (AC/DC adapter).
The 5V is regulated to 3.3V with an LDO regulator, which provides power to the entire board. The Atmel ATmega1284P is powered by 3.3V, but if 1.8V operation is desired, some modifications to the board are needed.
