hello Saoloog,

Many thanks for your response. Is there a maillist for someone interesed in buing the new product?

Thanks in advance.

sorry not yet.

I have a similar question... I want to add a Daisy AIS hat to a PICAN-M RPi setup. Could I use a hat stacker for this? I can't seem to find information as to which GPIO pins the PICAN uses. The Daisy uses ports 8 and 10, but perhaps others. Does anyone know?

I am afraid that is not possible, the PICAN-M also uses pins 8 and 10 (UART0).

The good news is that the MacArthur HAT project is still alive and we will be sending the first units to beta testers soon. It uses SPI0-1, UART3, and UART5, leaving SPI0-0 and UART0 free to be used by the dAISy HAT, Moitessier HAT (hacked and non-hacked versions), or any HAT that uses those pins. We are working on the documents at the moment and hope to publish all the details in February-March 2023.

That's helpful, thanks. I'm wondering if it's possible to directly connect the GPIO pins from the Daisy hat to the NMEA0183 port on the PICAN-M to provide the input that way. I use NMEA2000 input for all other data and so the NMEA0183 ports are currently empty.
