Intended application:
The C-Control Pro SD-Card Interface acts as a gate to the micro controller, for example the C-Control Mega 128 unit (Conrad item no. 198219),
to a 3.3V SD-Card. This SD-Card extension includes a level converter, which converts the signals bi-directionally and, thus, enables a direct
connection between a SD-Card and a 5V micro controller. All currently on the market available memory cards, e.g. SD, SDHC, MMC as well as
other cards can be used via an adequate SD-Card adaptor.
