 +
 +For end user, there is no difference.
 +
 +COMFAST CF-EW72 V2 is known to be produced in two variants (**not versions**):
 +  * COMFAST CF-EW72 V2 with MT7621AT and separate DDR RAM chip onboard.
 +  * COMFAST CF-EW72 V2 with MT7621DAT with integrated RAM and no DDR RAM soldered chip onboard.
 +PCBs for both variants seem to be same. Firmware works for both.
 +
 +COMFAST CF-EW72 V2 known to be sold both in unpainted cardboard box and colorful glossy cardboard box.
 +I guess, but not guarantee that colorful box is for new variant equipped with MT7621DAT SoC and no RAM chip.
 +Seems that devices also have different factory labels.

 +  * :!: It is recommended to connect serial adapter through active (with separate power) USB hub. Avoid connecting to usb port connected to computer motherboard. CF-EW72 V2 has 48V on PCB, and if 48V will somehow hit your USB, it may damage your PC, including CPU. 
 +  * In some situations device may not start when RX pin is connected - so, connect it right after you see output from device. 
 +  * Connected RX also may cause random 5GHz Wi-Fi chip problems.
