SuamdoenUSB to TTL Serial 5V 3.3V Adapter Cable TX RX VCC GND Pinout with 4 Pin 0.1 inch Pitch Female Socket FTDI Chip for Windows 10 8 7 XP Vista Android Mac OS (3.3V TTL logic Level)

I bought two of these for an OpenWRT development project, both would consistently error out after around 30 seconds to 60 seconds use at 115200-8-N.At this point, erroneous characters would be received from every device connected to via their TTL pins. Recovery was only possible by unplugging and plugging the USB cable in and out, power cycling the adapter. 30 to 60 seconds later the same issue would occur and erroneous characters would again be received.When using a different manufacturer's product using a FTDI chip connecting to the same TTL pins at 115200-8-N, no errors would ever occur.The wires on the items received were also different to those in the pictures.
