Fermion and Gravity data logger technical questions

1)      Fermion data logger: due to the possible SD card incompatibility please indicate the ordering number of the compatible ones (size is irrelevant, some MB are enough for my application)

Links provided in the product page of the  Fermion Serial Data Logger V2.0 for Arduino to the recommended SD cards point to a non available products.

If you don’t have this products please point me to a compatible products, in Digikey or Amazon …, thanks

2)      Please send me the user manual of both 

Fermion: Serial Data Logger V2.0 for Arduino as well as of the

Gravity : Serial Data Logger V2.0 for Arduino

data loggers

3)      Is UART cable provided for both boards?. Please provide a photo (I assume the connector to the board is also provided)

4)      Please indicate the diameter of the holes of both boards. They appears different  about 3mm for gravity and about 1,5mm for Fermion
