1st generation Cables
If you have 1st generation cables, where labels has text like:

1st generation cables do not have 3,3V output at all, many cases (high current 5V or 3,3v) targets need use external power supply which is problematic and confuse the users. Here you can find advised for external power supply using.
Please note: 1st generation cables and V2 cables are COMPATIBLE in pins, except the extra wires and features, applied in V2 generation. If you can find all color points of the wiring image, please connect all of them, and you can work.
If 3,3V point or EXT POWER notification can see on wiring image, you have to use external power supply, here we explain how. That is the main difference.
Also please note, some 1st generation cables GND point is PINK color, which is equal BROWN GND wire. PINK = BROWN
