CPU list

Chips currently supported by the project:

This list is not exhaustive, i.e. a similar chip (but different package) might work just fine, but there's no board definition for it yet. If you have an unsupported chip, feel free to reach out using Issues or on the Discord server.

Families

A list of chip families currently supported by this project.

Note

The term family was chosen over platform, in order to reduce possible confusion between LibreTiny supported "platforms" and PlatformIO's "platform", as an entire package. Family is also more compatible with the UF2 term.

The following list corresponds to UF2 OTA format family names, and is also available as JSON. The IDs are also present in lt_types.h.
