I've been searching for RPi's in this formfactor and with protected I/O for a while. Besides your product I found some others but all suffer from the same drawback (for me at least), which is the price. I can understand there is some extra cost involved in the certification of these devices, eMMC and such. Most industry customers will probably find the price resonable even. But for me as hobbyist I can't justify it to myself if I could buy a handful of 'normal' pi's instead (solving the DIN mounting problem using zip ties).
Do you think your company might develop a non-industrial line for hobbyists which could bring the price more into the range of sub $100?
