Get great AIS reception from this little box connected to lap top. Easy to hook up and quickly ID's boats. Helps spot the shrimp boats in the Gulf before we head out to go fishing.

We used the unit onboard a pleasure craft, powered through USB connection, displayed by open CP 4.0.0, connected to different VHF antennas:
the unit cannot receive signal beyond 2 nmiles
in this condition it is useless to us

Hi Adrian,

I would just like to share my thoughts on your dAISy AIS receiver. I have now had some time to play with it and have found it to be very good. It was easy to set up, just follow the instructions and you can't go wrong. I also bought a WiFi transmitter from Ali Express for a few dollars which also works well. As I have no experience with other AIS receivers I can't compare its functionality but I have been using it with Open CPN and it works well on my laptop, android tablet and Samsung phone. It seems to acquire targets fastest on my phone. Thanks for a very nice product at an affordable price.

I found the HAT to be well documented my only wish was that the i2c and 2nd serial had their pins pre soldered (I hate soldering small things)

But everything went smoothly for my project and I will probably be building another OpenPlotter for a mate.

ps. along with i2c and 2nd Serial, why not also add the 2x10 male pins on top of the HAT so that users can stack HATs on top of the current HAT.

I am really happy with this tiny little AIS receiver. There is only one point which could be improved: I have written a software which automatically detects connected receivers like GPS, AIS etc. independent of port and baudrate. This is easy with GPS because GPS sends every second a message even if no satellites are in view. Unfortunately dAISy does not send any message when no AIS message is received. It would be much easier to detect the dAISy port, if at least a state message would be send every 5 seconds. Currently I detect dAISy by sending an ESC character to the available ports to get an answer. But this is not a very safe method because I have to ensure to reset dAISy to receive mode.
Nevertheless an excellent product!
