Helium Atom
Development Board


The Helium Atom Development Board lives at the heart of your development workflow, allowing you to bring the physical world online. The Atom Development Board contains a Helium Atom Module, two on-board sensors, battery pack, and serial connection for script programming.

When powered, the Development Board will automatically connect to the nearest Helium Element Access Point and report temperature and pressure data, all viewable on the Helium Dashboard.

*Requires a Helium Element for full functionality.
