USB to 3.3v TTL PIN Header Cable

I got this cable because of it's RTS and CTS pins as well as being equipped with an FTDI chip and I definitely got what was in the description. Tested out on my JP1.x remote that needs the RTS line in addition to the usual TTL line - hence why I chose this cable over a cheaper 4-pin - and it works flawlessly. Build quality on first impression is good and looks to be on par with other well made cables but ultimately time will tell.As far as all the comments about no pin out information included with the cable, I can only assume the issue has been rectified as the PDF on the included driver/manual disk has a slew of information including the very valuable pin outs that happen to be exactly the same (color and pin location) as the genuine FTDI brand cable.

I was a little put off by the price when I ordered this, but it is a very universal serial connector and I've used it on Intel Galileo Gen 2, as well as BeagleBone Black. I don't believe this would work for a raspberry pi, for that you need the TTL cable with the separated headers. There is some added quality that is noticeable once you start to use it, there is an led in the usb plug that flashes with every keystroke - very cool.

After a slight modification, I was able to bring a bricked router back to life and install DD-WRT firmware to it. I give it 4 stars because there weren't very good instructions on where to find the drivers to use it properly, and it would have actually been a more useful item if it came with a pin header block and single wire jumper dongle. I've worked with TTL chips before and I've never used this cables TTL Header pin-out configuration before, so it seems to make more sense to just put single wire plastic jumper pin headers on each wire than putting it on this old school CD-ROM audio cable molding. But... there is probably some reason associated with mass production that I might not be aware of as to why that is.I ended up making my own out of an old CD-ROM audio connector in about 10 minutes though. It's pretty cheaply made too, but works ok. I wouldn't flex the joint where the cable meets the USB connector if you can avoid it.

It worked well to update the firmware of a wireless temperature sensor by PrivateEyePi. I plugged it into the USB port of my Windows 7 box. I tried to plug it into my USB hub, it was not detected properly. When I plugged it into a port on the computer, it was detected properly. I loaded the drivers from the CD, and it allowed me to transfer data on a COM port. It would be nice if drivers were downloadable somewhere, because I won't have a CD ROM drive forever. But for now, it works great.

[tl;dr: this cable ships without pinout info. it might be available online. buyer beware.]What a joke! The other fellow who reviewed this product went through the time and effort to FIND the MISSING PINOUT DATA for this product (without which it is WORTHLESS) and post it in his review.Luckily, before I or any other buyers could benefit from his research, Amazon's crack crew of simpleton dimwits helpfully DELETED the information. Otherwise, it might be helpful, you see!So to recap. Amazon has been made aware that this product ships without crucial documentation. Instead of rectifying the product with their vendor, so as to stop shafting their customers one order at a time, they actively remove the links to documentation that really is their responsibility to deliver with the product in the first place.It would be funny if it weren't so pathetic. I hate to use the cliche; but they really have gone downhill. When the shopping site you use can't sort a list of products by price, it is definitely time to move on.So bravo, Amazon! You have managed to actively repel a faithful decade-long customer (and Prime member). Based on my prior experiences with your phone CSRs, I won't attempt the impossible and try to explain this to one of them. All they seem to be able to do is repetitively drone out randomly picked scripted explanations and excuses for the particular way they've bungled an order.Edited to add: If you google the part number (SS-TTL3VT) you will find the pinout and other useful product data on a site called <...> under "USB to 3.3v TTL Header". Hopefully you can still find it even if Amazon deletes the URL again ( <...> ). Consider this a second chance at redemption, Amazon. Or, a second chance at screwing your customers. Your choice!If all else fails, here is the interesting info off the linked page:* UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity* Fully assisted hardware (RTS#/CTS#) or X-On / X-Off software handshaking.* Data transfer rates from 300 baud to 3 Mbaud at TTL levels.* +3.3V output allows external logic to be powered from the USB port* Transmit and receive LEDs* UHCI / OHCI / EHCI host controller compatible* Pin 1 GND* Pin 2 CTS* Pin 3 VCC (+3.3v!)* Pin 4 TXD* Pin 5 RXD* Pin 6 RTSI'm assuming that the black wire is pin 1.It's using the FTDI chipset:* Product ID: 0x6001* Vendor ID: 0x0403 (Future Technology Devices International Limited)* Version: 6.00* Speed: Up to 12 Mb/sec* Manufacturer: FTDI* Current Required (mA): 500

I would imagine that the cable would come with the wiring chart of the pin-outs but noting came and I was forced to do research on the Internet to get the information.After viewing the pin-outs, it all worked fine.This could be the problem with the supplier or manufacturer for lack of documentation.

Used this to make a custom cable for a device that needed a TTL level serial connection, worked perfectly and love the molded connector that lets you see the TX/RX LEDs on the board... do wish it came with some documentation as to what colors are what signal but was able to make an educated guess from the pin numbers listed in the description

The review that stated it put out 5V on VCC made me a little bit nervous. I decided to take the chance, and am happy to report that VCC on my cable puts out 3.32V. The standard FTDI driver works just fine, and it follows the standard FTDI 3v3 cable pinout/wire colorings.If you're buying this cable, you're probably a bit of a hacker. The fact that it doesn't come with a paper manual shouldn't bother you much.
