The CompactFlash module is powered by 12 Vdc received from the datalogger
through the peripheral port.
The CF cards do not require power to retain data.
Typically, a CF card can be erased and rewritten a minimum of 100,000 times.
Industrial CF cards, graded for 2,000,000 write cycles, are recommended for
most applications.
