Manual
All Mikroelektronika's development systems feature a large number of peripheral
modules expanding microcontroller's 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.
