SteadXP devices are recording motion data at 24kB/s, so using this 2 GB microSD card, you have a 24H autonomy.
We recommend formatting your microSD card (1GB to 32 GB) with the SD Memory Card Formatter, using FAT16 or FAT32.
Warning: exFAT formatting is not supported by SteadXP devices.
Warning: you should save any data stored on your microSD card before use with SteadXP devices, as the first time you insert a new microSD card, SteadXP will format it.
Warning: avoid formatting your cards with “Disk Utility” if you are working on macOS
