Running windows 7 and Sigma Studio 4.2 and best I can tell all worked identically to the ADI USBi that I have. My rating for the documentation is fake because I plugged it in and it just worked, so no need to RTFM...
And I like the case to stop me from having it accidentally land on other things that would release the magic smoke found inside of the ICs.
I bought a couple of these adapters in an effort to find something simple, inexpensive, and FDTI-free that would work with my Mac. (Shipping took a while, but that's to be expected from China to the US.) The adapters seem to be well constructed, much better quality than the typical Chinese stuff you find on eBay. Documentation is quite good.
When I first plugged it into my Mac, no new serial ports showed up in any of my serial terminal apps. I went to the documentation link on the Tindie product page, and under the installation section for OS X I found a link to download the required driver:
Installation Summary for macOS 10.13 "High Sierra": Download and install driver. Allow kernel extension under System Preferences -> Security & Privacy when prompted. Reboot. Re-install driver. Reboot. Done.
Helpful Installation Notes: I really don't like disabling system integrity protection (SIP) to get drivers working, but I was pleasantly surprised to discover that on macOS 10.13 "High Sierra", you actually get prompted to allow the kernel extension under System Preferences -> Security & Privacy, rather than being forced to disable SIP, which can be a real pain to do, and also a security risk. After reboot nothing showed up, so I decided to give the installer another go. After the final reboot, everything worked! I did not need to disable SIP. :)
Finally, a macOS USB-to-serial converter that works!
The hardware quality is amazing. But I could not find any information for the software. Where is it? Because I could not found the software for this board, I made Arduino STM32 variant, https://www.youtube.com/watch?v=b_IgPVzI7hU . The board works very well with the variant.
This USB-UART adapter just does the job, the way it has to be done. Documentation is excellent, even when installing it on Windows 10 doesn't require any user intervention, and the pins are perfectly documented on the PCB as well.
I have ordered the module with straight pins, facing down, which unfortunately wasn't shipping safe, and the pins were bent in the envelope. I could straighten them, and even if they were broken, they could be replaced easily. However, it would be nice to have the option to order with the pins unsoldered, and leave soldering to the customer.
An other small issue is when connecting the module to a breadboard with the down facing pins, the module is not fixed tight enough to the breadboard, and the torque caused by the USB cable can loosen the module. It would be nice to have an other set of pins at the other end of the PCB (even if they are not connected to any function) to keep the board in place.
But even taking these minor annoyances into account, I am completely satisfied with the product. Thank you!
Thanks for the review. It is glad to know that my product worked for you.
Regarding the issues you have pointed out here, the "straight pin facing down" option in M180-Series really is a kludge for breadboard users (since I am using it, both on breadboards and as part of the developer's kit of M177v2,) before I could release a proper, breadboard-friendly USB to Serial interface using a DIP-style design, breaking out all pins from CH340G, not just the ones defined in the SparkFun 6-pin interface. The DIP-like package can be protected using foam or tube during shipping, and will sit tightly on a breadboard.
