MicroSD card specifications
The MicroSD Flash Storage Card (microSD card for short) is used to log flight telemetry and
image telemetry data on-board the GeoSnap system control unit. The card used must meet the
following requirements:
MicroSD ( SDHC)
Sandisk Ultra MicroSD recommended
System successfully tested with 4GB, 8GB, and 16GB SDHC cards
Formatted as FAT32 (exFAT is not supported)
To use a new microSD card in the GeoSnap system, make sure it meets the requirements above
and is blank. Insert the card into the system, power on and wait for a couple seconds, then
power down and remove the card. The card will have been populated with a default CONFIG file
that you can then edit to your requirements.
