I am interested if they make an open source lock-in amplifier with the two channel analog inputs. I made some progress in that direction using NI hardware and labview, then I graduated. I wish someone makes a lock-in amplifier app. An off-the-shelf amplifier device costs over $2K. I hope their ADC has enough gain (should be why not) to amplify millivolts.
This is very interesting to my research side. Equipment has always been expensive.
I don't like microusb for power though, flimsy!
The two symmetrical 2-row connectors are good to look at but they may want to put some keys in them so people don't accidentally plug cables into the wrong port.
