### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    A nice cheap serial-to-USB option
  

*by G***O on Reviewed in the United States on October 7, 2024*

If you need the option to convert TTL logic via pins to USB, a feature usually included as part of most development boards, then this fits the bill pretty well. It also has options to work with 5v or 3.3v and can provide power via USB to the connected device.

    The FT232RL of my dreams
  

*by B***T on Reviewed in the United States on September 9, 2023*

I have been dreaming about this chip ever since I was a kid. Finally, it comes in a three pack!!! OMG!!! I was looking to flash opensource software on my IoT devices, and this allows me all the connections that I need. I finally feel whole now that this chip is in my life. I remember when this chip came to my house. The sun was shining, birds singing, and a new patch had just been released. This day will go down in history as the day I got my FT232RL.

    2 out of 3 don't work, avoid!!!

Only one of the three units works because it seems the manufacturer programmed the product/vendor ID so it is not recognized as a UART.Here is the working one:[947593.026440] usb 3-1.2.3: new full-speed USB device number 18 using xhci_hcd[947593.238487] usb 3-1.2.3: New USB device found, idVendor=10c4, idProduct=ea60, bcdDevice= 1.00[947593.238515] usb 3-1.2.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3[947593.238532] usb 3-1.2.3: Product: CP2102 USB to UART Bridge Controller[947593.238547] usb 3-1.2.3: Manufacturer: Silicon Labs[947593.238560] usb 3-1.2.3: SerialNumber: 0002[947593.280277] cp210x 3-1.2.3:1.0: cp210x converter detected[947593.283114] usb 3-1.2.3: cp210x converter now attached to ttyUSB3Here is what the rest of the adapters report:[947635.271389] usb 3-1.2.4.1.4: new full-speed USB device number 20 using xhci_hcd[947635.491544] usb 3-1.2.4.1.4: New USB device found, idVendor=11ca, idProduct=0204, bcdDevice= 1.00[947635.491568] usb 3-1.2.4.1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3[947635.491582] usb 3-1.2.4.1.4: Product: VeriFone USB to UART Bridge[947635.491594] usb 3-1.2.4.1.4: Manufacturer: Silicon Labs[947635.491605] usb 3-1.2.4.1.4: SerialNumber: 0001Why are they reporting that they're a VeriFone USB to UART bridge?!?!? The CP2102 chips should not be programmed (I use these chips a lot in my board designs).
