Development Kits

The development boards for the Librem 5 are built around the EmCraft i.MX 8M SoM, a development platform based on the i.MX8 CPU. There is a list of Known Issues with the development boards.

It is possible to develop software for the Librem 5 without a development kit. If you are developing applications that do not rely on specific features of the phone, or that only need to be tested for use on a small screen, it can be practical to use an emulator to help with development.

Also take a look at the How To Guides page for some common commands and routine tasks.
