SH-U09C USB to TTL Serial Adapter with FTDI FT232RL Chip Compatible with Windows 11, 10, 7 and Mac OS

The FTDI drivers are flawless unlike the CP2102 drivers which are old and outdated. 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).

It's a good overall. It's work great 👍 I try to use in my old router.

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...

Worked perfectly with no driver issues

Update: The boards work perfectly in every way, except with the Reyax RLYR998 LoRa boards. On Windows, Linux, Raspberry Pi, or Android, they just will not work with the LoRa board. I have returned the boards and changed my rating from 5 to 4. I had no installation problems at all. The boards are seen as "com12" on Windows and "/dev/ttyUSB0" on Linux and Raspberry Pi. I found that the "cutecom" program is available on all three platforms, which gives me a good way to use them for initial testing or to interface to Reyax LoRa radios. Using various online examples, I was able to make a little Raspberry Pi Python program use the boards. Other terminal programs that worked for me are: "Serial USB Terminal" on an Android phone, PuTTY,HTerm, gtkterm, screen, cu and Picocom on Linux, PuTTY and Terminal.exe on Windows. However, I came to learn that that the Raspberry Pi has its own "UART" built into the GPIO pins. If you want to control a Reyax LoRa Radio from the Pi, you don't need these DSD Tech boards at all. Just hook up to the proper GPIO pins, enable serial I/O in raspi-config, and specify /dev/ttyAMA0 instead of /dev/ttyAMA0. From a Python program, the GPIO pins and the DSD Tech board are used in exactly the same way.

I needed this to program a Nextron LCD display via a USB port. At first, my Nextron screen showed only lines and static. Then I realized the power jumper was set to 3 volts, and the Nextron required 5 volts. After that, no problems. It just works.

I bought this adapter to interface a uBlox Neo-8M GPS module to use as a time reference with PPS to create a stratum 1 NTP server on Windows 10. It powers the GPS with no problem. I soldered a lead to the CD (carrier detect) hole on the PCB and connected it to the PPS output of the GPS module. It works, but be careful. It appears that the RS-232 control signals (CD, CTS, RTS, DTR, DSR, etc) are inverted. So my PPS driver was triggering on the falling edge of the CD signal instead of the leading edge. I was able to compensate for this by using an offset.

I bought two of these for ESP32 Cam Boards that do not have a USB Port. It connects with the included 8 Pin Female To Female ribbon cable. There are two jumpers included. One selects either 3.3 Volts or 5 Volts for power, and the other is a jumper cable that connects RX and TX to test the adapter. I am very happy with my purchase and use them quite often.

Propre parce que le boitier protège bien la clé et permet de la manipuler sans problème. Fiable parce qu'elle a fonctionné tout de suite sans avoir besoin de drivers (sous MacOS/Unix en mode terminal). Enfin, au niveau des plus : - Elle est livrée avec un câble de raccordement des pins (femelle-femelle), Que je n'ai pas utilisé car j'avais besoin de mâle-femelle, mais j'étais déjà équipé. - La puissance de sortie est suffisante pour alimenter/flasher un module ESP8266 (Shelly à rendre compatible Homekit). Pour le moment, j'en suis très content.

Good Solution for Serial port converter, used to reset the Electronic devices. Thank you.

Honestly I havent used for some reason not related with product.

usb to rs232 works well easy to get up and running . no software (drivers) required for windows or linux
