Olimex AVR-CAN

The Olimex AVR-CAN is an inexpensive way to learn how to use an AT90CAN128 microcontroller from Atmel.

It's in a very compact form 60x55mm and the presence of both CAN and RS232 allows the customer to make a bridge between the UART and the CAN networks. All AVR pins are available on extension connectors and the board can be easily connected to a snap-on prototype or to other mother boards where additional circuits are built.

The board includes useful features such as an onboard 5V regulator (input voltage 7-12V DC), user button, reset button, status LED, power supply LED and more.
