Frequently Asked Questions

A Notecarrier is a carrier board for a Notecard.

Notecarriers expose a Notecard’s interfaces through convenient breakout connections, and integrate essential supporting circuitry, including power regulation, protection, and signal conditioning. This allows developers to focus on firmware, connectivity, and system behavior without first designing a complete custom carrier board.

Every Notecard-based project requires a carrier board to power and interface with Notecard. You don’t have to use a Blues Notecarrier specifically. For production designs, many customers build their own custom carrier board instead of using an off-theshelf Notecarrier.

However, for development and prototyping, we strongly recommend using a Blues Notecarrier to get up and running quickly. Some customers also choose to use Blues Notecarriers in production deployments.

No. Connectivity is determined by Notecard, not Notecarrier. Notecarriers provide the physical connections needed for Notecards to operate, but they don’t change how connectivity works.

Some Notecarriers, like Notecarrier XS and Notecarrier XI, include slots for Starnote modules. These slots make it easy to add satellite connectivity, but the connectivity itself is still provided by Starnote, not Notecarrier.

Notecarrier A provides onboard cellular/WiFi and GPS antennas. For other Notecarrier models, you’ll connect external antennas directly to the Notecard. All Notecards ship with flexible antennas that you can use for development.
