CP2104 Serial Converter USB 2.0 To TTL UART 6PIN Module compatible with and better than CP2102

I recently got my hands on the WINGONEER CP2104 Serial Converter USB 2.0 To TTL UART 6PIN Module, and I must say, I'm pretty impressed. If you're in need of a reliable serial interface, this little guy is definitely worth checking out. First off, let me tell you that this module does exactly what it promises. I had no issues whatsoever using it as a serial interface. The inclusion of jumper leads is a nice touch, saving you the hassle and extra expense of buying them separately. Now, if I had to nitpick, I'd say that a protective case would have been a nice addition. You know, just to give the module a bit more durability. But honestly, considering the affordable price point, I can't really complain. It's a small trade-off for a product that performs so well. Overall, if you're looking for a cost-effective and efficient solution for your serial communication needs, the WINGONEER CP2104 Serial Converter is a solid choice. It's straightforward, reliable, and comes with everything you need to get started. Whether you're working on a personal project or a professional one, this module is definitely worth adding to your toolkit.

Plugged into my Windows 10 machine and was recognised straight away. Ran Putty with tx/rx loopback - echo worked straight away. Far better than the cheaper FTDI232 I got from another supplier where the header pins didn't want to work - probably why it was cheaper - but then this isn't expensive (wish I'd bought it first) It has 5v and 3.3v pins - I use it for programming some STM32 devices - they happen to be 5v tolerant on the RX/TX pins but some devices need only 3.3v so this will work with either. It was delivered with a cable as per picture. However, if, like me, you spread your electronics about on your desk then you need to get a USB A male to female extender OR a longer 6 way extension (harder to find). I did find some 50cm jumper wires from sourcingmap on Amazon - they would help.

Very basically engineered unit, no casing, bare PCB, header cables very short, best to use with a USB male/female extension cable. Requires care in use to avoid shorting out exposed terminals or PCB to equipment being monitored. No additional drivers were required with Win. 8.1 or 10 operating systems. Accepting these limitations, the unit does work very well and offers the choice of 5v or 3.3v VCC provision, overall, deemed good value for money.

I bought this for project work with Arduinos, and others, where I only had a TTL Uart signals which I wanted to connect to my laptop and access the projects with applications written in Delphi. As I and using a Windows 7 64 laptop I had to download and install the driver, (google CP2104 to Uart bridge controller download, and get to the Silicon laboratories website) I installed it as per instructions, plugged the device in and it worked. I used TeraTerm as the port driver on COM10, and I looped TXD back to RXD, and Viola! it worked! Even the serial port configuration options in TeraTerm controlled the device. For the price, a brilliant piece of useful kit is you are involved with Uart connections to electronic projects

Used this to programme various devices with custom firmware including BTHH5, Openreach modems, Sonoff switches etc. Works well.

Cheap simple and worked like a charm.

Worked exactly as described for the purpose for which it's intended.

Does what it is supposed to do.
