Add support for ZBT-Z8103AX-D

Opening this thread as a sibling to thread

It appears that there are a lot of similarities between model D and model C while working to get support for ZBT-Z8103AX-C. Got positive feedback from an owner of a model D for using firmware of model C.

Intention is to prepare a PR to get support for ZBT-Z8103AX-D.

Things I got about ZBT-Z8103AX-D so far:

  • Owners do use self compiled images currently.
  • Self compiled images state device as a ZBT-Z8103AX (without any model designation)
  • Motherboard in a model D is the same as in a model C
  • Device characteristics are equal between model C and model D (confirms motherboards are identical). The obvious difference is the enclosure and external antennas (model D) versus internal antennas (model C)
Efforts to support ZBT-Z8103AX-C (model variant C sold in 2025)

Thanks for doing this. Happy to help if you need any more details about the ZBT-Z8103AX-D.

Good job, best is to continue in existing threads.

Hi @brada4

do you have an existing thread to suggest that I should continue? My first guess was to start this new one, but I’m willing to learn.

You posted in 2 of them, hope somebody tests and helps with a review

Here my first questions:

  • Are there two buttons? One named “Reset” and another one named “Mesh”?
  • Please have a look at MAC address of WAN interface. Does it show MAC address printed on the Router label?
  • What about MAC addresses of wifi interfaces? They should show
    • address printed on Router Label -2 for the 2GHz radio and
    • address printed Router Label -1 for the 5GHz radio
8
  • Yes, there are 2 buttons labelled "Reset" and "Mesh"
  • Yes, there is MAC address printed on the label, please see photo. It corresponds to the MAC of eth1
  • The 2.4GHz MAC ends C6
  • The 5Ghz MAC ends C7

partition@580000 {
label = "ubi";
reg = <0x580000 0x7a80000>; // 980 * 128KB blocks
};

Hi @emba
Did you try your partition layout?
Do you have any source for proposed change of ubi partition?

The factory layout wastes nearly 8MB of usable blocks, this 0x7a80000 is my calculation that perfectly aliens the 0x20000 Erasesize and fills the physical gap
