Specification:<\/h3>\n\n- True two channel receiver, continuously receiving on AIS channels A (161.975 MHz) and B (162.025 MHz)<\/li>\n
- Superior sensitivity compared to other low-cost AIS receivers<\/li>\n
- Low power, less than 200mW in receive mode (<40mA at 5V)<\/li>\n
- 38400 baud serial output in industry standard NMEA format (AIVDM)<\/li>\n
- Communicates with Raspberry Pi via UART0 (serial0)<\/li>\n
- Works with Raspberry Pi 1 (A+\/B+ only), Pi 2, Pi 3 and 4 (see note below), and Pi Zero<\/li>\n
- Shape and size compliant with Raspberry Pi HAT standard<\/li>\n
- Breakout pads for 2 independent TTL serial outputs, 3.3 and 5 volt rails, and Raspberry Pi I2C port<\/li>\n
- SMA antenna connector<\/li>\n
- SMA-to-BNC adapter and hex standoffs included<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
Note: On the Raspberry Pi 3 and 4, UART0 is occupied by the built-in Bluetooth radio. Bluetooth may not be available when using the dAISy HAT.<\/p>\n
dAISy can easily be combined with OpenCPN and OpenPlotter<\/h3>\n
OpenCPN<\/a>, an open source chart plotter and navigation software, can be used with receivers like dAISy to track ships on a map. Any software running on the Raspberry Pi that accepts AIS data from a serial input will work with dAISy.<\/p>\nSeveral of our customers built chart plotters based on Raspberry Pi, OpenCPN and dAISy. A detailed step-by-step recipe can be found\u00a0here<\/a>.<\/p>\nWith\u00a0Kplex<\/a>\u00a0the Raspberry Pi can be setup as a NMEA server that distributes AIS to other devices on your network, like for example via WiFi to a navigation app running on an iPad or Android tablet.<\/p>\nDisclaimer: WE DO NOT RECOMMEND to rely solely on dAISy for navigation and collision avoidance!<\/strong><\/p>\n![\"Screenshot](\"https:\/\/github.com\/astuder\/dAISy\/raw\/master\/Pictures\/opencpn%20screen%20small.png\" "\\"Screenshot")

Sending date to lifeguardtracking\/AISHub of MarineTraffic<\/h3>\n
The dAISy HAT works perfectly to send messages in the standard NMEA format to services like lifeguardtracking.nl<\/a>, AISHub<\/a>, or MarineTraffic<\/p>\n![\"Ships](\"https:\/\/github.com\/astuder\/dAISy\/raw\/master\/Pictures\/MarineTraffic%201492-2.png\" "\\"Ships")

dAISy in comparison:<\/h3>\n
With\u00a0our open source work<\/a>, we pioneered a new category of AIS receivers designed around the\u00a0SiLabs EZRadioPro<\/a>\u00a0single chip radio IC. This architecture is instrumental for the very low price, small form factor and low power consumption. The trade-offs are longer acquisition time, lower sensitivity and less range than some traditional AIS receivers.<\/p>\nField tests with conventional dual-channel AIS receivers showed, that under good conditions the dAISy HAT can be on par with some models (e.g. SmartRadio SR162) while still being outperformed by others (e.g. advanSEA RX-100). However dAISy clearly outperforms all sub-$100 receivers that we have tested so far (Quark-elec, MarineGadget).<\/p>\n
Our observation is, that with a good antenna dAISy is well suited to monitor local ship traffic. If you need maximum performance and are willing to pay for it, go with a receiver from the established brands.<\/p>\n
Warranty<\/h3>\n
Our AIS receivers are professionally assembled in the USA. We offer a 6 month warranty on the product (excluding physical or water damage). Please contact us<\/a>\u00a0if your AIS receiver prematurely fails or if you encounter any other technical issues.<\/p>\nShipping.<\/h3>\n
dAISy HAT will be shipped after receipt of payment.<\/p>\n
