Save yourself the headache and trouble and pay 5 more dollars for the FTDI chips, you will thank yourself in the future. The variable voltage selection jumper on this converter is very useful for handling hardware that runs on 3.3V instead of 5V, saving yourself the hassle of buying, owning, and subsequently finding the right voltage TTL reader. The jumpers included on this were also nice. Great value, would buy again, would recommend to anyone looking for a TTL reader. Use case: Reading serial terminal data off an SBC due to bugged OS compilation software (a lot of bootleg, or alternative rpi clones do not have reliable wifi config options when compiling and writing the software to the boot media. Often, these have no video output, so doing any computing becomes impossible. You need one of these to change the settings on the OS after initial boot to connect to your network to SSH into them). Review: Works great and includes everything I needed - I needed to revive my router. This USB to TTL adapter with included cable worked perfectly. Windows 11 automatically installed it as a COM port without needing drivers or any compatibility issues and with the use of putty I was back in business in no time... I like that the 3.3v vs 5v jumper is clearly visible - no danger of getting it wrong... Included cable is a little stiff but ok to use - just make sure everything is connected correctly before powering on the adapater and the device you are connecting to... ## Features - With this USB to TTL adapter, you can establish communication with your board/MCU via your computer. Maximum transmission speed up to 900K. - The main chip is FT232RL from FTDI, high stability. LED indicator for TX, RX, Power supply. It is very useful when you debug or download. - PIN definition: CTS, RTS, RXD, TXD, GND, VCC, support 3.3V and 5V VCC outputs, switch by jumper. - Works with Windows 10, 7 (32/64bit) Vista 2008, XP, 2003, Mac, etc. - WARRANTY: We support this FDTD USB to TTL converter with 12 months warranty.
