Hi everyone,

We’ve successfully tested **Wi-Fi HaLow (MM8108-EKH19)** with **NVIDIA Jetson Orin NX** and are now designing a **custom board**.

We plan to integrate **MM8108-EKH19 (RD09V4 USB-to-board)** directly on our hardware.  
Could someone please share:

- Reference schematic for the MM8108-EKH19 USB adapter

- USB, power, reset, or layout guidelines for custom board integration

Happy to proceed under **NDA** if required.

@nasihabdulnazer nice work getting the board working on the Jetson!

If you have time, do you mind writing it up as a “build thread” in the [projects](https://community.morsemicro.com/c/project/11) category?

Thanks @ajudge Glad to hear it’s useful 🙂  
Yes, I can write this up as a build thread. I’ll document the Jetson Orin Nano + RD09 V4 bring-up steps and post it in the **Projects** category shortly.
