Third-party Modules

DUELink is designed with one important goal in mind, to work with all other ecosystems and allow users to make their own modules! We are giving you everything you need to make your own DUELink modules. We only ask you not to use GHI Electronics and DUELink logos without written permission from us, see Legal Licensing for details.

Beside that, we have got you covered, from hardware to software!

Hardware​

The micro we use on DUELink is STM32C071. You can integrate this micro on your modules and you are halfway to having your own DUELink modules!

If you are not comfortable using a very tiny QFN32 chip, we have made Stick, which brings all the connections to 0.1” headers and castellated holes. It also includes both U and D connectors.

Pencil Stick

The Sticker, is the development board for the Stick, which brings all its available connections to pin headers for easy prototyping and testing.

We also offer Stamp, an ultra-small board with USB C connector on-board.
