There is a difference in the engraving of the logo on these chips. Please note A FTProg utility that's part of the official FTDO FW cannot recognize the device. Latest update The serial number A50285BI is part of a common fake serial number list- It does not work with libftdi the way it does with a genuine EEPROM chip using the same program, so it must be performed manually. - However, the device name on the chip has the L*br- suffix, while it is missing from the USB name There is a release number in the EEPROM of 0000*- My other laptop does not even turn on after I unpack it. Because I am inverted, I cannot use my chip. Then maybe this will work if the only thing you need is a simple non-proprietary format This is an inverted serial adapter supporting standard baud rates without bitbang, but none of the fancy FTDI features appear to work.
As a result of seeing the other review, I knew the FT232RL chips were probably fake. Based on my verification - It is possible to check the serial number of each chip, which is unique to real chips, and see that they all display "usbserial-$" The A50285BI code. It is possible to swap the chip for real one, if careful soldering is done on the SMDs. You can find a comprehensive description on the web by searching for "Fixing Fake FTDI FT232RL Adapters". The fakery here is not appreciated by me.
The way they work is fine. It's a bit annoying that the ft232rl chip is a fake, but if that is the only way you intend to use them, these will be fine. That's pretty impressive. I'd love to know how they are able to do it. The FTDI part has an eeprom that can be programmed, the Chinese part does not, or at least it cannot be programmed with the software provided by FTDI. Other Chinese vendors make that clear, and they warn you that the part is not genuine. It is important to exercise caution if you intend to construct a system that combines more than one of these elements. If you want to assign a specific port number to a specific device, Windows requires a unique serial number. Since the VID and the PID are both the same, and they should be, the lack of a serial number means Windows cannot distinguish one device Bringing them online in a certain order does not appear to be a way to correct this problem. If this is what you wish to do, you may well buy the counterfeits and then replace the chip with the genuine Although you will not save as much as when purchasing a unit with a genuine FTDI part, it might still be worth it.
These are cheap and mostly work, but they have (as predicted) counterfeit FT232RL chips that all have the same serial number - this is not uncommon. You can't use different browsers on the same computer for many reasons, because there is no way to tell which one is which.
A50285BI is a common serial number found on fake FTDI FT232 chips and is found on all of these FT232 boards. I have not been able to do serial communication successfully with these boards, despite the fact that they are partially functional, using the genuine FTDI driver. Genuine chips have unique serial numbers, which allow them to be interfaced to more than one PC at once. They bear the trademark of FTDI, and are presented to the customer as the real thing, and not as a copycat.
The quality of these is superb. The FTDI drivers for Windows 10 are made and are immediately recognized. The four components are all assembled on the same In order to separate them into four separate boards, you will have to snap the boards apart by yourself. There are no micro USB cables - instead they use the "old" USB mini (not micro) cables. They aren't included in the software, so you'll need to find one. I really like the price! Loops are useful for - Based on a back test, all four are in good working order.
Four units were delivered to me, each with a unique serial number. When I tried to reprogram them with the FTDI software, it appears that they are programmed Using these devices with Windows will work, but the COM port number will bounce depending on which USB slot you place them in. VirtualBox is running Linux in my lab, and only the first one gets passed through and assigned a port name of /dev/ttyUSB0. Those other than you will not be able to.
To install, you will need to download the setup executable from the FTDI site. Although the process is somewhat challenging and involves a bit of work, you can do it With the RX and TX pins connected directly to my application's respective TX and RX pins and the GND connected, I was ready to run the application. Ensure you select the correct voltage level for your application as well. The number I used was A three-volt battery.
