CP2102 Module USB to TTL 5PIN Serial Converter Adapter Module Downloader for UART STC 3.3V and 5V with Jumper Wires

Got a pack of these for some microcontroller projects and they worked immediately after installing the drivers without any weird issues. The fact that it supports both 3.3V and 5V is super convenient since different boards need different logic levels and it's annoying when you have to figure out workarounds. Comes with jumper wires too which is a nice bonus so you don't have to dig through your entire parts bin right away. One of mine had a slightly loose USB connector but a quick touch with a soldering iron fixed it in two minutes. Good value for the price.

The IZOKEE CP2102 Module works exactly as expected. Setup was quick and straightforward—drivers installed without any issues, and the module was immediately recognized by my computer. It supports both 3.3V and 5V, which makes it versatile for different projects. The included jumper wires are a nice bonus and make prototyping much easier. I’ve tested it with multiple microcontrollers, and the data transfer has been stable and reliable every time. Build quality feels solid for the price, and the compact size is perfect for my toolkit. Overall, this is a dependable USB to TTL adapter that’s affordable, easy to use, and great for hobbyists and developers alike. Highly recommended!

Worked great to flash a Luckyminer LV06 to Axeos. Good price and had it next day!

Hit or miss QC it seems.... Received 2X boards, one worked perfectly right out of the bag, the other had a very loose USB connector and was continuously connecting/disconnecting from the PC when plugged in. Upon further investigation it seems the metal USB connector was not soldered to the circuit board, not even a poor solder job... but zero solder. It was only hanging on the pc board by the two metal tabs on the side of the connector. Anyway, a quick two min fix with the soldering iron and the connector was now making contact with the four pads on the board and it worked perfectly when plugged in to the computer. All-in-all a decent deal if you're willing to possibly put in a little effort to overcome factory QC over-sites.

The product is excellent; I only needed one, even though two were included, so I'll have a spare. I needed it to control an old NAS I had at home, and it worked perfectly. I just needed to install the Windows drivers and use PuTTY to access the serial port console. So far, it's worked wonderfully, and I recommend it if you can only access the device's interface via the serial port.

This unit still had issues running at 115200 clearly. Dropping the rate to 57600 cleaned everything up, and the connection was rock solid. I was hoping for the best case; but seriously the visual difference between the two speeds was visually undetectable, and I'm not transferring large data chucks.

Works as expected, however the CP2102 is locked and therefore unable to change the VID/PID if required

This guy works great. This converter interfaces directly to the TTL Rx and Tx serial pins of common microcontrollers. The logic level of these microcontroller pins is inverted RS232 and the device operates like a MAX232 except the output is USB and not RS232. Connection to a computer requires a MALE/FEMALE USB cable and not the standard dual male type. I view the output with the TERA TERM emulator. The applicable com port can be discovered in the device management menu (WIN X) under COM PORTS.

Nice little units and works on Mac and Linux

Used this to reprogram my nightshade. Works great, no issues.

This bi-directional converter 5V/3.3V does what it is supposed to do fine, it connects via single header connector wires to the device you want to connect to; this cable harness comes with the converter. Since it has a male header connector, it is a little bit difficult to connect the single header wires to it and maybe in the future, due to continued use, there may be some damage to the male header connector on this converter. If you don't plan to be taking it on and off, I think this device is perfect for the application; I recommend it. The text written on the circuit board is clear, so that you know what each pin of the male header connector is identified.

Only used 1 of the 2 so far to connect to a Cisco spa122 and unlock it. Everything worked as expected without any issues. Did not do any further testing so can't comment on the 3.3volt or 5volt connections. I was able to accomplish what I wanted so I am happy with the purchase.

cool product ! i use it on linux with some software on there, it does what it does !
