This is a good product, works as intended, no complaints: 5 stars. Just be careful and know that they have no output voltage to power your device. The mistake I made. Order -5.0 or -3.3 if you want to connect the red wire.
Pros
has no power (0 volts). The USB connector contains a small circuit board with a FTDI FT232RQ UART serial interface IC to handle all USB signals and protocols.
