Over breakfast this morning had a quick look into if the AZDelivery device stands a chance of working, two things stood out:
. Relatively few passives
. A jumper for 3.3 or 5V
Now i know from my TFDI RPi device, that it must be possible with few passives. Whist my C232HM-DDHSL-0 cable has alot more passives in - but is a beast of a cable.
So anyway downloaded the FT232R datasheet, it does indeed have most of the required components inside, all it needs outside is a few decoupling capacitors, and a ferrite to stablise current, and maybe a few pull up resistors. 3.3 and 5V can be done by a jumper, the USB gives 5V, and the chip has internal 3.3V source, either can be used to drive the output stage, so yes can be done by jumper - there is even a reference design.
So whats the conclusion, the AZDelivery device has about the right complexity needed to be a working FT232R device. Can't speak for the quality of the soldering, anyway may be worth a punt. Can't say I've ever heard of AZDelivery though as a company - if I was to guess, I'd suspect a chinese company.
Anyway up to you, but if you use embedded things, you'll find the cable useful. Great for talking to arm boards, or arduninos and so on. Just wish I could get the C232HM-DDHSL-0 cable to work as JTAG ...
Oh yes googled AZDelivery:
https://www.az-delivery.de/products/ftdi-adapter-ft232rl?variant=36542809426, looks like a small company from Bavaria. This has to make it more likely that the device is good.
The device though is generic, probably from china:
