MCU Cards Manual for BIGAVR6 development system All Mikroelektronikas development systems feature a large number of peripheral modules expanding microcontrollers range of application and making the process of program testing easier. In addition to these modules, it is also possible to use numerous additional modules linked to the development system through the I/O port connectors. Some of these additional modules can operate as stand-alone devices without being connected to the microcontroller. Additional Board2 MCU Cards for BIGAVR6 Development System The BIGAVR6 development system is supported by empty 64- and 100-pin MCU cards. Schematics provided herein show these MCU cards with soldered microcontrollers. Instead of microcontrollers used in these examples, you can choose and solder another ones. Prior to soldering, check which microcontrollers can be placed on the respective MCU card just to be sure that they are compatible. MCU cards are also provided with pads that enables you to access microcontroller pins when the MCU card is not connected to the development system. Supported microcontrollers:: 64-pin MCU cards support the following microcontrollers: ATmega32U6, AT90USB64 and AT90USB128 64- and 100-pin MCU cards (MCU Card 1) support the following microcontrollers: AT90CAN32, AT90CAN64, AT90CAN128, ATmega64, ATmega103, ATmega128, ATmega165, ATmega169, ATmega325, ATmega645, ATmega3250 and ATmega6450. 64- and 100-pin MCU cards (MCU Card 2) support the following microcontrollers: ATmega1281, ATmega2561, ATmega640, ATmega1280 and ATmega2560.
