Hi Dirk and others,
yes, the hardware is capable of full MITM. We haven't yet written the software (both firmware and host software) for it, but we are confident that it will work.
The 100 unit hardware manufacturing is scheduled for mid next week, which should give us ample time for testing, flashing and possibly debugging any issues that may arise during that production run before the camp.
And yes, I was referring to the camp as availability time.
The price is not fixed yet, but I would expect somewhere in the order of 75 EUR, including a set of four SIM card adapters. This may seem a lot given the BOM cost, but it's actually "just" the production cost plus the hardware cost we had for doing the two prototype runs, plus some amount that we need as a safeguard for dealing with warranty related issues (mandatory legal warranty for products is 2 years in the EU). Also, the SIM card dummy adapters are surprisingly expensive to get hold of :/
All time spent in doing the hardware design (schematics, layout, firmware, host software) is volunteer work by Kevin and me.
Regards, Harald
