Blackout Comms Compatible SD Cards

We highly recommend selecting a known-compatible SD card for use in your device, if you're using SD cards.

These are what we include in devices we ship. They're available from Amazon and work quite well.

Keep ONN (Class 10) 32 GB

Generally available in Wal-Mart stores.

SanDisk Ultra A1 microSDHC UHS-I 16 GB

SanDisk Ultra microSDHC UHS-I 16 GB

Available from Amazon

Much of the hardware used by Blackout Comms is very picky about SD cards, and won't work with most > 32 GB cards. If you attempt to initialize your device and it becomes stuck (for more than 20-30 seconds) on the mounting SD step, it's likely your SD card is not compatible.
