+- [nim-littlefs] - A Nim wrapper and API for littlefs. Includes a fuse

+- [chamelon] - A pure-OCaml implementation of (most of) littlefs, designed for

+- [mklittlefs] - A command line tool for creating littlefs images. Used in the

+- [pico-littlefs-usb] - An interface for littlefs that emulates a FAT12
+  filesystem over USB. Allows mounting littlefs on a host PC without additional
+  drivers.
 
 - [Mbed OS] - The easiest way to get started with littlefs is to jump into Mbed
   which already has block device drivers for most forms of embedded storage.
