A part of the review has been auto-translated.
Bien, conforme à la description
this all in one USB interface will be very useful for many situations
Everything is good except a week late delivery.
Works quite nicely. I don't use the +5V or +3.3V outputs, I'm just using it as a 3.3V RS232 to USB adapter. There is absolutely no documentation except what is printed on the PCB's soldermask. Fortunately, very little effort was required to make it work. The CP210x drivers for the chip are easily downloaded after a Google search and install fine into Windows 7.
super handy for arduino and sonoff hacking..
It works as described. Im happy with it.
This is a handy TTL and RS programmer (5V or 3.3V settable). This one works for programming devices with the Arduino IDE.
There is no delivery on Sunday. How come it is well receipted.
As described. Functions immediately on Windows 10. Excellent for testing.
Very good quality.
