Evaluation board Propox EVBAVR03
EVBavr03 is a development board designer for the hobbyist and engineers who want to quickly prototype their system based on AVR microcontrollers from Atmel.
Detailed Description
Developer has access to all pins of the micro, which are brought to the header (pin connectors) and labeled accordingly. Depending upon the board`s configuration (listed versions) some or all of the following components are found on the board: potentiometer, two relays, buzzer, RS232 interface, JTAG connector, RTC (real time clock), 7-segment LEDs and LCD display (2x16). The pin headers provided allow easy access to all these components. In addition, there are eight micro-switches and eight diodes which could be connected to any of the pin connectors or additional components, which may be placed on the large, adjacent prototype area. The power circuitry on board (bridge, voltage regulator) eliminates the need for an external regulated power supply.
This board comes with the several examples of the C code routines (source from), to facilitate testing and quick development in using the board`s resources.
