This is a brand new product with documentation still work-in-progress. Don't hesitate to contact us for more information.
The dAISy Mini is a dual-channel AIS receiver with integrated low-noise amplifier (LNA). Thanks to its small size and low power consumption the dAISy Mini is ideally suited for embedded applications.
AIS (automatic identification system) is an automatic tracking system for ships. Ships broadcast their position and other information over VHF. The dAISy Mini allows you to receive these transmissions, enabling real-time tracking of nearby vessels.
The dAISy Mini outputs the AIS data as a stream of ASCII messages, which are encoded in a marine standard format known as NMEA AIVDM sentences. This format is understood by applications and devices like chart plotters, marine traffic aggregators, and can be processed by many opensource libraries.
The dAISy Mini is designed to be integrated with microcontrollers, single board computers and flight controllers.
All functions of the dAISy Mini are available on 0.1” headers. 5 V power supply, 3.3 V serial, and optionally I2C are also available on the 6-pin JST-GH connector with a pinout compatible with the Pixhawk telemetry port.
We also carry a matching USB adapter to connect the dAISy Mini to a PC for configuration and debugging.
