FTDI USB UART IC FT232RL' USB to Serial Converter for Development Projects

Looked alittle questionable upon arrival but flipped the physical switch to 3.3v, plugged and played on Windows 11 using kali vm on VMWare against a known good IoT camera with uart pins. Worth it!

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!----

This worked perfectly for flashing Tasmota onto the Sonoff Zigbee bridge using Tasmotizer -- for integrating with HomeAssistant (HassIO)!My flashing process was a slightly finicky but overall smooth -- after trying to take a backup of existing firmware via Tasmotizer the device became unresponsive. But it's hard to say if it was the device or the software. Had me worried for a moment, but after a hard reset (unplugging & plugged back into the PC) it it started working again. And the normal flashing process was smooth after that.Tip 1: (as noted in other reviews) the connection labeled VCC is the voltage connection that will output the voltage as set by the onboard switch (3.3v for my use case).Tip 2: I found some different cable sets on Amazon that included male-to-femaile as well as male-to-male wires in one set. This let me use a breadboard for joingin the grounds together instead of mucking with the way that is presented on the video.Tip 3: BUT, these wires did not fit in the holes of the Sonoff Zigbee pcb nearly as easily as shown in the video. IN fact they didn't fit at all initially. But upon close inspection I could see that the male ends of the wire are folded over (not solit) so by squeezing them with pliers, to deform them, I was able to get them small enough to wedge into the PCB with a pretty solid connection and flashing went smoothly after that!I bought this wire kit:https://www.amazon.com/gp/product/B07GD2BWPY/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&th=1

Good versatile usb-to-uart interface. Works on 3.3v fine, didnt test 5v. Durable and well-built.PS: for beginners: RX on the programmer goes to TX on the device, and TX on programmer goes to RX on device. I got this wrong in the beginning and was trying to figure out why it wasnt working. This isnt a mistake, this is how serial is designed (RX is recieve, and TX is transmit, so transmit of one has to go to recieve of the other).

I've got a Seeeduino Ethernet MCU that requires a USB to TTL adapter in order to upload sketces to it.Having purchased a multi-pak of cheapies to use in collecting data from some Arduinos, I assumed they would work for this application, and I was wrong. I spent quite a bit of time trying to get to get the cheap converter(s) working (tried a couple of them), but no luck.Since at this point I really had no way of knowiing for sure if it was the converters or the board that was faulty, I searched for the cheapest converter with the best reviews, and found this one. It helped that it was available with one day delivery.As another reviewer pointed put, the soldering quality is pretty sub-standard, and I figured I just threw $10 away. I needed to use the DTR function, so soldered a header in place, and connected it to the MCU and my PC. The power light came on on the adapter and the MCU, so that was a good sign.Upon opening the IDE and clicking the upload button, I was very happy to see the red and green winky-blinks light up as the sketch uploaded without issue.So bottom line is that the unit works fine, but is slightly to the shabby side of quality.

got what i ordered works intended

Item works as intended. SPI flashing no issue with correct voltage. Hope it lasts for a while.

I had a problem with another adapter that did not have enough current at 3 volts to flash a Sonoff S31 Smart plug with Tasmota. I had to rig a supplemental power supply to do it with the other unit. BUT this adapter works great. No supplemental power required and flashing was a breeze.
