OS4000-T Nano Compass

Product Announcement from OceanServer Technology, Inc.

OS4000-T Nano Compass-Image

The OS4000-T is a nano size (0.6" x 0.6") three-axis, tilt compensated digital compass. The compass is connected via TTL only. The OS4000-T provides precise heading, roll and pitch data ideal for rapid attitude measurement. The OS4000-T offers an easy to use ASCII interface which includes hard and soft iron compensation and simple data configuration for your application.

Important note: the OS4000-T is a through hole package intended for volume applications where it will be mounted directly on a user's system board. First time users should purchase the evaluation kit which includes the OS4000-M Translator/Carrier Board (includes connectors for USB or RS-232). The -M board is offered in the OS4000-T evaluation kits so users have a quick reference on how to hook up the module and create the holes in the user design to mount the OS4000-T. The OS4000-M is only for initial development and debug. The evaluation kit includes a user CD with the schematics and layout in the Eagle format.
