Teardown of a Hantek 2D72 3-in-1 handheld oscilloscope #ReverseEngineering
Kerry D. Wong documents a teardown of the Hantek 2D72 3-in-1 Handheld Oscilloscope/Digital Multimeter/Arbitrary Waveform Generator.
On the reverse side of the display board, you can see a USB connector that is recessed from the edge of the board. I am not entirely sure why the USB connector was deigned not to be flush with the edge of the board as the port is quite recessed making it more difficult to plug in the USB cable.
There is also an empty footprint reserved for an ESP8266 module by the look of it. Again, could it be that Hantek has a future version planned that incorporates both an SD card and a wireless module?
