Hi 
I bought voxl2 I/O expander board with MDK-M0065-02.
Does it flash any image in voxl2 I/O expander board ?
If yes, how to read version from voxl2 I/O expander  board ?

Another, where to download modalai_voxl2_io_bl.bin and modalai_voxl2_io.bin? I would like to connect it with voxl2 board for our development.

Thank you
