Review: Worked great to unbrick a Belkin RT3200 / Linksys E8450 affected by OKD (OpenWRT kiss of death) The included cables have female and male ends and so did not directly connect into the JST PH connector (also male). I inserted the male ends from two cables together and then used the combined cable to connect the CH340 to the router. The ends connected to the JST PH connector were a loose fit.
Review: I used one of these to adapt my cellphone with the rxtxlite android app to my uSDX+ V2 qrp transceiver. Everything went together easily, and worked perfectly. Now I can change bands, modes, and adjust frequency with the phone instead of the buttons on the radio. Cheap and easy to do! I would recommend.

### ⭐⭐⭐⭐⭐ Review
*by T***) on 24 March 2019*

These are by far my favorite USB/TTL devices. For one - there's a jumper that allows selection between +3.3 or +5V. The other cool feature is that they are using the CH340 chip. I've found this to be significantly more reliable on Windows as compared to the other commonly used chip - the SiLabs CP201x. The problem with the CP201x chips is with Windows - so many times after Windows updates are applied, the drivers are replaced with a default that causes them to no longer function until the proper drivers are manually re-installed from the manufacturer's web site. That's not the case with these using the CH340. They always seem to just work. (not an issue for linux, of course) I also like the fact that these devices have clear heat shrink tubing, protecting these devices (and your computer!) from stray wires or other things that inevitably fall on them during development and prototyping. As an extra bonus, M-F jumper wires are included; great for connecting to breadboard (but note that you'll need F-F jumpers if connecting directly to something like a Raspberry Pi) Note the default jumper setting connects the Tx/Rx pins as shipped; this allows for immediate operational verification using something like putty to confirm operation using serial loopback.
