Introducing the new MacArthur HAT - Sailoog - 2021-02-18 We are delighted to present you the new project we have been working on these months: The MacArthur HAT We have been analyzing the most requested features from OpenPlotter users and we have been able to gather all of them in the small space of a HAT for Raspberry Pi. Specifications
No idea yet but as cheap as possible as usual. When? The design stage is done and we are waiting for the first prototypes to be tortured. We will inform here when we have a release date. Feel free to post here any comment and suggestion RE: Introducing the new MacArthur HAT - MigGat - 2021-02-18 Cool! Can't wait RE: Introducing the new MacArthur HAT - CapnKernel - 2021-02-19 (2021-02-18, 08:28 PM)Sailoog Wrote: Looks so nice. The analog inputs numbered AIN7, AIN6, AIN5, AIN3, AIN4 (ie, out of order) may make it easy to make wiring mistakes. RE: Introducing the new MacArthur HAT - BTsail - 2021-02-19 Very cool, looking forward to trying it out.. Any thoughts on adding a small DC-DC 10V-16V -> 5V on-board? Then you could power directly from the NEMA2000 power wire directly!

Any thoughts on adding a small DC-DC 10V-16V -> 5V on-board? Then you could power directly from the NEMA2000 power wire directly! We considered that but finally we choose the external converter because: - There is no enough space in the board - We will have less electrical interference. We will have IMUs around so it is better to have the DC-DC conversion far away. - Drone power modules have a very clean output. - This way we will have consumption measurement of the whole electrical circuit. This is not possible taking power from the NMEA 2000 network - Lot of people use UPS HATs, so we need the powering feature to be optional. - Using this way you still can take the power from the NMEA 2000 wire.

RE: Introducing the new MacArthur HAT - SkipperEarly - 2021-02-19 quote NMEA 2000 in/out. It is not isolated so be sure you power your NMEA 2000 network and your Raspberry from the same source. unquote any chance to reconsider and enable isolation or make available optional? RE: Introducing the new MacArthur HAT - Sailoog - 2021-02-19 Again the available space and the price makes difficult isolation. Obviously isolation is always better but we do not think it is a critical point if all devices share the same power source. If I were worried about isolation I would buy an isolated USB converter like the Canable and I could use it in my Raspberry and in my laptop safely (different power source). RE: Introducing the new MacArthur HAT - Lazzz - 2021-02-19 Is the GPIO app still going to be finished & supported so we can run sensors without the hat?? Is the Iot app still a work in progress? |
