GAGALOR 1 Meter USB to TTL Serial Port Cable RS232 0.1 Inch 4 Pin Female 3.3V Converter

Having a "bricked" device I wanted to get the serial output to try repairing it. I made my own USB cable, but it wasn't stable enough.I found this listing, seeing the reviews about it not being authentic I decided to give it a shot, since the price was low. Upon plugging it in on my Windows 10 machine the commonly seen "THIS IS NOT PROLIFIC PL2303." text shows up. However I could still edit the driver settings, so I tried it on my older Windows 10 laptop. This time that name didn't show up in Device Manager. Instead it showed "Unknown USB Device (Device Descriptor Request Failed);" which is what would show up with my homemade cable.This led me to believe it was a driver issue, not hardware. I started looking for older versions of the driver and found a few. Even Prolific had an older driver listed on their website. Sure enough after I "updated" the driver to an older version it showed up properly in Device Manager and allowed me to use PuTTY, removing the "road block" the new driver was causing.You'll see in the pictures I added that it's working with the correct driver name. I even tested it with the "Check PL-2303 chip version" utility that comes with the new driver, showing that it's an XA/HXA chip....the product Prolific states is EoL and not supported anymore.I wish the leads were a little better labeled, and a slightly larger gauge. I had to figure out which color for data went to which pin.For me it was: white = Tx green = RxRed and black are easy, being voltage and ground.Hopefully this review helps others looking as I wanted to share my experience in getting this cable to work.

Non sono riuscito a farglielo vedere da windows 11 ed alla fine ho dovuto comperare un'altro cavo di altra marca. Peccato, sembrava fatto bene. Non ho avuto voglia di sbattermi a fare N tentativi e reinstallare driver o quant'altro.

Buy a different product if possible, like other reviews say- the product does not have genuine parts and will be a pain to deal with. I wish I tested it earlier and was still able to return the product. Bought it way in advance for a class but now can’t use it.

I use this all the time. Never fails to be recognized or connect and use at a bridge device. It does what it says and iv already gotten a couple more. Great for roboticss

I needed this to program ESP8266 micro-controllers. It works for that (thankfully stepping the power down to 3.3V, which is what the ESP8266 needs). The little female wires are reasonable durable, but I still wouldn't be rough on them. Note that the USB A plug is rather large, probably because it needs to step down the voltage from 5V to 3.3V with a a couple of resistors. I recommend this cord for easy access to the four pins of a standard USB A connection.
