SD Cards

We recommend using Sandisk Extreme UHS Speed Class 3 (U3) microSDHC and microSDXC cards with AudioMoth.

Other cards may also be used but be sure to test them first. Slower cards, such as Class 10 or UHS Speed Class 1 (U1) cards, may not work consistently at high sampling rates.

 

SD cards typically come formatted in one of two systems. Cards that are 32GB or less in size are normally supplied formatted using the MS-DOS (FAT32) system. Cards greater than 32GB are typically supplied formatted using the exFAT system.

 

From AudioMoth firmware version 1.2.2 onwards both FAT32 and exFAT file formats are fully supported. However, if you are using an earlier version of the AudioMoth firmware ensure that your SD card is reformatted as a MS-DOS (FAT32) card prior to use, or reflash you AudioMoth to use the newer firmware (see instructions here).
