As a potential potential customer for this Drotek positioning product (and not experienced yet in this field), I have a few questions:
How do you charge the batteries? Seems there is no charger provided.
What are the connection means with external devices? Only the micro USB port visible on the photos? No bluetooth?
Which external device could be plugged with the 2 JST-GH 6 pins cables?
Is there a (microSD or other type) memory slot?
What would you recommend to protect it from rain, direct sun, etc?
