ShillehTek FT232RL Mini USB to TTL Serial Converter Adapter Module (2pcs) | 3.3V/5.5V Dual Voltage | Compatible with Arduino, Raspberry Pi, and Microcontrollers

I really needed one of these a long time ago. This makes connecting serial port devices to your modern PC easy by letting you adapt the pins to a USB port. It even has a switch for 5v or 3.3v serial power expanding the number of serial devices you could use with it. It's a bummer that the USB port on this device has to be a USB-mini, one of the worst USB formats there are, but I was able to use this with my PC, Mac, and Linux computers without any problems and got usable data right off the bat. Plus, the design of the chip makes it easy to use with breadboards for experimentation.

Got these for a project I am working on, and was able to get a basic test out one of these (which is all i really needed), and it worked great! For the price, these are a great deal - they came quickly and in great shape!

FTDI, the company that makes the chip used in this product, got ticked off at Chinese manufacturers piggybacking their drivers. They were so ticked off they released Windows drivers that brick Chinese clones. Google "FTDI gate" for the full story.With these boards I'll be able to use up-to-date Windows drivers.

So far so good. Nothing really exotic about these but they're handy to have around the shop when you need them

These USB to Serial Adapters work as they should. They are good for programming a chip or a board, such as a replacement chip for an Arduino, or an ESP32 board. They can also be used as a method of powering a board such as an ESP32-cam, which does not have a USB port. Plug the USB power into the "Mini USB to TTL Serial Converter Adapter Module," then attach the power and ground from the module to the ESP32. These also have a jumper to switch between 5v and 3.3v. Be sure to set it up as needed. Note that this has a Mini USB and not a Micro USB or USB-C port. You will need a USB to Mini USB in order to use this module.

I’ve had a great experience with this USB to TTL adapter. The dual voltage option is convenient, and the mini USB connection feels solid, though it’s worth noting you’ll need the correct USB cable. It’s a handy tool for any electronics project, offering reliable connections, but make sure to grab non-official drivers for the best performance.

Make sure you get the drivers for this. I would not recommend the official FTDI drives as the company is horrifically unethical and has a history of bricking devices intentionally.With that said, this works just fine. I've bricked a handful of these on accident so it's nice to have a few on hand. These are fantastic, affordable little devices and a must have for any tinkerer. You would be surprised the amount of off the shelf gadgets that use a common programmable chip that you can hack into and tweak. It's also necessary to program a ton of dev boards that don't have the converter baked in, such as Arduino Pro Mini.

I work with cameras and other devices that use serial port for initial configuration. There are several common types of USB-TTL adapters and this one is one of my favorites, because:- It does not plug directly into USB port, you need an extension cable, which allows placing this adapter next to the target device and using shorter TTL jumper wires.- it conveniently switches between 5V and 3.3V TTL levels- The adapter is based on the very common FTDI chip supported by most operating systems without additional drivers.- It uses larger Mini-USB socket, which is more reliable than smaller Micro-USBManufacturing quality is above average, and the price is right.
