Smooth sailing, I read don't use the newest drivers ymmv

Smooth sailing, I read don't use the newest drivers ymmv
This is the same module that the soft-spoken guy with glasses on YouTube uses, Dronebot Workshop. There are warnings about Windows bricking this unit using a newer driver. Download the FTDI drivers from 2010 or 2013? And after Windows automatically installs a driver upon connection, go ahead and roll back the driver manually picking the one you downloaded. Before plugging it in I downloaded the driver. If you right click on the INF file and click install it will be merged into windows available drivers and you should be able to just pick it from a list manually when changing it.If that's too complicated for you, you probably shouldn't be using this anyway or by the genuine FTDI! There's nothing you're doing with this, programming arduinos and esps, that can't be done with the old driver. It will simply show up as a com port to your computer. you can change the comm number assigned to it in device manager. Be sure to set the 3.3 or 5 volt jumper. If you're doing Dronebot's esp32 cam project, you will need more power (current) if running it through the module to test it without a separate supply. The esp32 cam sucks down some juice! For that use the 5 volt jumper to the 5 volt pin is the esp instead of the 3.3v as he suggests and put the jumper back on 5v. Smooth sailing.

5.0 out of 5 stars It does work!
Reviewed in the United States on November 18, 2017

It could be faked FTDI chip as others claimed. But, to be fair, it does work for its purpose. I used it to flash several ESP8266 based SonOff devices many times. There are two things I learned in the process though I would like to share:

1) This chip could output 3.3v or 5v. It is on 5v when I got it. You can switch to 3.3v using the jumper close to the output pins. If you are flashing ESP8266 devices like me, make sure you switch to 3.3v first!
2) Make sure the USB cable you use to connect this to your computer is a data cable, not a charging only cable. This was the reason it did not work for me at first.

5.0 out of 5 stars Used it to mod my car's infotainment center.
Reviewed in the United States on August 22, 2022
Verified Purchase
I used this to hack my '17 Yaris iA's infotainment center (which is identical to what is in a Scion iA and Mazda3, I believe.) It worked as well as any debugger. A couple dupont jumpers into the appropriate harness, a gator clip to the fins of a heatsink for ground, fired up PuTTY, stuck a stock firmware update image on a USB drive alongside the mod patches/program and ran the update in the car. I watched in the console window as it did it's thing, leaving me with a root shell afterward to run the patches and mods. And now I can mirror my phone, enable touch while driving, turn my car into a WiFi hotspot, play video files on the screen, use custom interface themes/backgrounds/animations, and a whole plethora of neat features. Not bad for <$10 and an afternoon of effort. Lately, I've been getting more into STM32 microcontrollers to make DIY music instruments (Teensy, Daisy Seed, Arduino), so I think this debugger might be relevant there as well and get a second life. I keep it with the cheap STLink V2 clone in my tools, and a coil of 6" dupont jumpers in case the kit is ever needed.

4.0 out of 5 stars Not all FT232RL Functions Supported
Reviewed in the United States on January 13, 2022
Verified Purchase
For the price, this is a very nice FT232RL-like USB-to-Serial converter board. I like that it breaks out all of the pins to solder pads to make it easy to integrate into projects and connect things as needed. For basic communications, it does a decent job.

I remove a star, however, because it doesn't support all FT232RL functions. I know it's not a genuine FT232RL chip, and I really appreciate the seller disclosing that in the product description and on their website. So I wasn't expecting a "perfect" FT232RL clone. However, what is missing is a detailed description about the differences between this clone and the real FT232RL chip.

I needed an adapter that could support Tx/Rx signal inversion to communicate with a single-wire half-duplex FrSky S.port -- something that the real FT232RL chips can do. I was able to use the ft232r_prog tool on Linux to read the EEPROM settings from this board, and the settings read out just fine and reported reasonable values for how it was configured. However, it refused to accept the setting changes to invert the Tx/Rx signals and it would simply switch those settings back to defaults.

Those were the only two options I needed to change, so I didn't spend a lot of time trying all of the other option combinations to see what it would accept and what it wouldn't. I assume some of the options, perhaps LED settings or something, might be supported. But, I had no choice for my project except to switch to a board with a real FT232RL chip (a SparkFun board to be exact) and it worked just fine with Tx/Rx inversion, albeit at nearly three times the price.

I do like this board and will keep it for other projects that don't require special configuration. For basic communication, I recommend it as a cheap alternative. But, be aware if you need to reconfigure this chip, it doesn't support all FT232RL options that the real FT232RL supports. And they don't tell you exactly what features it supports and what it doesn't. Also, if you are on Windows, the FTDI device drivers might render this board inoperative by changing its USB VID/PID values so Windows won't load the device driver for it. I use Linux, though, and had no problems using this board, except for the special configuration options that it doesn't support.

5.0 out of 5 stars Inglamorous, just does what it needs to.
Reviewed in the United States on June 1, 2020
Verified Purchase
I have purchased this three separate times over the past couple years, and only problems I've ever had were due to my own ignorance.

I've successfully used these to program ESP32's, arduinos, as well as providing UART between my computers and various embedded chips (i.e. PIC32MZ, some motorola chip in a handheld gaming unit).

Most problems come from not understanding how to connect it to the intended device. Some very basic rules:
1. RX connects to TX, and TX connects to RX. RX to RX and TX to TX doesn't work, hopefully understandably.
2. Even if you don't connect 3.3 or 5v power from your FTDI board to the device, you need to connect the GND to your device's GND. Without doing this, you'll have unstable communications.
3. Make sure you choose the right logic level (3.3 or 5v) using the jump next to the connector pins. I successfully killed an Arduino by failing to do this. Don't repeat my success in this area.

Other than that, these inglorious little boards have done all that I wanted them to do and more. They're inexpensive, and for me at least, have just worked (once I overcame my own lack of knowledge on their use). I recommend it to others who are looking for a flexible device for either their programming or communication needs with embedded processors.
