What is the physical memory(ROM) in VOXL2? Also are there any technical feasibility to add more physical memory through any SSD extenders?

Hi @Jetson-Nano 
This page compares on-board support for all of our products.
https://docs.modalai.com/voxl2-feature-matrix/#specifications
You'll see Voxl2 has 128GB of on-board UFS Flash

Yes, you can expand Flash size by using our J5 expansion port SDCC (or UFS1) interface.

We have some plug-in boards that expose these for development, but otherwise you need to make a custom plug-in board for your needs.
Let us know if you need any extra help here.
Thanks!
