This ist the top of the assembled stick - without the mobile, this is taking the foto.
That’s the (not really) secret content of the box.
Just quick and dirty protection for the module and fixing the cables.
No RF shielding, so not realy intended for top edge in harsh environment.
All the parts fit into an ammunition box I got from a local hardware discounter some times ago.
And that box (about 7 x 30 x 45 cm) fits into the top case of my motorbike.
There were even some place for the mobile and a power bank.
