Divine D Rev. 1.1: MainPCB Layout Complete.
The layout phase has wrapped and the boards are now in production.

Besides the changes previously mentioned here (https://docs.dawndrums.tn/blog/dd-rev1.1-arch), what's more making it into this revision:

- RK3172 LoRa module
- LG77L as a standalone GNSS receiver
- Three chip antenna for WiFi, Bluetooth and GNSS, with high efficiency
- Mechanical optimizations for a more compact 5.5" design.

More updates once the fab house delivers.

@dawndrums 5.5" is a neat size, thank you.
Show threadfür immer und ewig2d ago
@dawndrums is there a estimated release date and a price?
Show threaddawndrums2d ago
@insl The estimated price is still around the range of 599-799 USD. We will communicate release dates after hardware validation, which is expected to be before July this year.

@dawndrums

Is there are reason for

  • M.2 B-key GSM and 4G module

    • This reads like there'd be a problem with using a 5G module?

    @me @dawndrums
    from what I saw 5G modules with call support are hard to source for non-OEM costumers

    @gpereira @dawndrums there's a 5g module available by simcom which works inside a librem5...
    Show threaddawndrums2d ago
    @me The requirements of 5G connectivity are technically demanding at the moment. This includes power consumption, number of antennas, module size, etc. Supporting it for the current hardware would add a layer of complexity to the current development rodmap, which is already packed. Nonetheless, as we move forward, we always revisit features for their value to our community.

    @dawndrums Thanks for the answer and for the great project!

    I hope we'll get a Linux mobile phone that'll support all features 🙃 .

    Just in case - the modem I put for testing inside a Librem5 is SIM8202G.

    If you're interested in testing - let me know 😉 …

    @dawndrums very exciting! Will the device support alt-dp on usb-c or is hdmi the only video out?
    Show threaddawndrums2d ago
    @dubstar_04 Our development rodmap includes full support of USB-C. Displayport over alt-mode, USB3, OTG and so forth will make it to dawnOS.
