Couple of questions about Mecha Comet

Mecha Comet
1

I learned about the Comet recently and it is really exciting, I have a couple of questions though:

  1. Hardware specs indicate both 2242 and 2230 for expansion, which one is it? I am assuming the latter as it is shown in the storage category.
  2. i.MX 95 version still indicates 2K display output, despite the ability to support 4k. Is this an error in specs or limitation?
  3. Specs indicate 4G modem, but on order page it is still “coming soon” - any ETA on that?

Thank you!

Hey thanks for putting this post up. Here are the answers

  1. The M.2 area can support 2242 and maximum 3042 form factors. 2230 can fit inside but there is no separate screw to hold on 2230 modules, but extenders are available
  2. Our hardware design allows the DisplayPort over Type-C to scale to 4K, because we are using two 4-lane LVDS as an input to our LVDS to DP controller. As per processor reference, via odd-even pixels this can give us combined bandwidth that can drive 4k30. On practical side, we havent been able to get 4k30 working on the evaluation kits due to multitude of reasons, but we got 1080p60 working. So we are waiting to test this properly on the Comet’s IMX95 board that are yet to arrive in two weeks from now.
  3. The LTE modem is installed via M.2 that you can bring on your own, or you can get the modem+antenna pre-assembled from us or buy the modem+antenna kit from us latter. We just got everything cleared off in this week from antenna design, regulatory and carrier support point-of-view. The modem will be available as an addon latest by next week on the Mecha Hub (hub.mecha.so)

Hey! thanks for working on this, the product looks great.

Any update on the LTE extension timeline? Is it possible to upgrade existing preorder so that the module is installed before shipment?

Hello @shoaibmecha,

May I ask you :

  1. does LTE include Wifi calling, please ?
  2. it is planned that you will offer a LoRa kit too ?

Thank you !

Hey

  1. LTE does not include WiFi calling, more details here- Wifi Calling : LTE - #2 by shoaibmecha
  2. It is not officially announced, but we do have it in our roadmap. We will probably get to it in towards end of this year or early next year.

Great, thank you for your answer
I think it is the same on any Linux smartphone for wifi calling unfortunately
Thanks again,

Hello,
I am waiting for the release of an AZERTY keyboard to order a Mecha Comet
While waiting for it to come out, I’m doing some research, and I’d like to ask a few more questions here:

  1. is there a GPS in Mecha Comet ?
  2. is dual boot possible on Mecha Comet ?

Thanks again and good luck for the next steps

Hey

We have published an update on our blog for AZERTY and also for LTE - Mecha: For the love of computing

  1. The LTE modem will support GNSS.
  2. Dual boot is possible, our standard flow uses UEFI images, you can have multiple entries in the boot partition. Also you can have separate boot from emmc and SD card, and select during boot time.

Thank you very much @shoaibmecha
I guess GNSS stands for GPS ? I didn’t know it is linked to LTE modem
Thanks again !!

May I ask a question : in the update of your blog, there are a lot of mentions of the LTE modem
You refer to carriers’ compatibility for EU without distinction, I hope the european carriers have uniformized standard

Besides, have you evaluated the Specific Absorption Rate (SAR) for the LTE upgrade kit pre-assembled with modem (Quectel EM060K-GL, voice enabled) ?

Thanks again and congratulations on your progress !!
