Appears to be a rock-solid FTDI chip.
Automatically detected by both my Windoze 10 and MacOS 10.12 systems.
The supplied little jumper shown in the pictures installed between TXD&RXD is there to check loopback.
If your terminal program echoes what you type through its assigned virtual serial port, it’s working properly.
Obviously, remove before actual use.
Perfect for use for its advertised purpose: a general-purpose firmware loader.
However,
If your primary use is with Arduino platforms that do not feature their own USB
(eg. Arduino Pro Mini and clones, and others):
it works fine, with the Arduino IDE & avrdude, *if* you keep in mind:
1. You’ll have to rearrange the order of the pins into the Arduino, as this unit does not follow the “standard” Arduino FTDI pinout ordering.
2. You’ll have to run a extra (preferably green) wire between the unit’s pad labeled “DTR#” and the Arduino’s DTR pin.
I soldered a long right-angle pin to the unit’s DTR# pad and created a rearranged female-female 6-conductor cable,
observing the “standard” FTDI “green/black” wire color & ordering to minimize the probability of connecting it backwards.
Again, if your primary application is Arduino FTDI, there are other, smaller, cheaper, standard-wired, genuine FTDI adapters out there.
Nevertheless, I kinda like this one.
It’s one of the few FTDI-based adapters to feature a USB Type A” connector, useful if you want to to plug it into your laptop without a USB cable.
One nitpick: I would have liked to see a schematic somewhere online, but have not found one, yet.
Still, does what it claims, so 5 stars!
