    I haven’t had time to mess with it yet but it should work as long as you’re supplying separate power to the pi and hat. I’m not sure how the higher power requirements of the rpi5 itself would fare with the pi2aes supplying power to the pi, the pi4 wanted 5.1v at 3A and the pi5 wants something like 5A and iirc uses the pd ability of the new stock psu in some capacity (unrelated to actual voltage though).

    The 5A includes usb, the real need is likely much less. The PI2AES P3.x actually delivers up to 5A. The PI2AES itself uses less than 100ma of that. Also because it delivers this to the PI via the GPIO pins it does not need to be 5.1V. The extra 0.1 V is due the the voltage drop on the USB-C power input.

    Note that the PI2AES 2.0 does not have the internal supply. It accepts 5V in, but this is not designed to supply the PI as well. Only the PI2AES.

    is the new version of pi2aes lite coming soon? any foreseeable issues with pi5 use?

    With mercury we decided to limit the hats to the PI2AES 2.0 only. We are looking at a new hat in the fall that will include analog (as suggested by a previous poster). Possibly Modular that will have a low cost base version with only coax along with the analog. Then an add on that provides AES, optical and I2S.

    All still TBD.

    Hi Michael. Your website still says "The PI2AES-LITE is Sold Out, new version coming in May!". I take that to mean a new Lite version so you might want to clarify if that version is no more.

    thanks for the heads up. I went ahead and changed that to tell people to take a look at the 2.0. At this stage because of chip availability issues we are just going to focus on the 2.0 and the mercury V3. At least until the Fall.

    So, I guess I have to eat my words! We had a batch of PI2AES-LITE boards that need one of those key parts. Turns out I was able find enough extra to release 100 of the boards. So the PI2AES-LITE is now back in stock. Delivery is 1-2 weeks from now, but 1-2 days after that.

    Thanks @Michael Kelly for the quick fulfillment! Just following up on my own post here;

    https://www.superbestaudiofriends.o...y-your-pc-or-laptop.8878/page-134#post-427245

    The Pi2AES works fine with the latest Rpi OS (Bookworm). All I needed to do was add "dtoverlay=hifiberry-digi-pro" to the /boot/firmware/config.txt and it shows up in the audio device list. Did not have to disable the HDMI audio or mess with Alsa as mentioned in the link in my above post. Was much simpler than I thought it might be. I now have VLC outputting audio and video via HDMI to the home theatre, and Strawberry sending music to the Pi2AES and via coax the the Bifrost2/Jot2.

    It may or may not sound as good as using a dedicated music player OS like Moode or Volumio, but being able to do both music and movies on the one device allowed me to retire the rather ancient laptop that was doing media player duties in the living room. All in all super happy with how it worked out.
