Hi, The hardware version of the board can be found written on the silk screen (either 1.0 or 1.1), The firmware version of the pysense can be found by using the read_fw_version() function in pycoproc.py which can be found here. Finally in regards to what library version you are using, you can see that at the top of the .py file e.g: __version__ = '0.0.2'

@fsergeys You should measure power draw from battery, not USB. There's a lot more going on when powered via USB, it's not representative of what happens when you're running on battery. You can definitely use the Pytrack's deep sleep (use the PyTrack library) to power down completely the WiPy, but you shouldn't see much of a difference when running from battery in the case of a WiPy 3.
