What capacity SD cards can be used and what's the file partition format used?

The SD card needs to be formatted to the primary FAT32 MBR partition type.

Polyend Tracker is offered with a 16 GB microSD card, larger SD cards can also be used as long as they are correctly formatted (The built-in disk-utility under Mac OS will allow you to select FAT32 for formatting).
We recommend UHS-I cards / U3 cards.

If you are on Windows 10/11, formatting bigger cards (32+ GB) to FAT32 can be a bit of a pain.

Here’s a quick guide that will help you achieve this:

  • Format the SD Card with the default Windows Formatter as exFAT (leave all default settings)
  • Download the GUI version of fat32format here: Ridgecrop Consultants Ltd
    • Click on the Picture to download it
  • Convert / Format the card once more in that utility to FAT32 (leave all default settings)
