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)
