## Description

CP2102

Review: Reliable and Easy-to-Use USB to TTL Converter! - 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!
Review: Managing an old NAS - 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.

## Questions & Answers

**Q: What voltage are the Tx/Rx pins? It looks like you might be able to change to 3.3 or 5.0**
A: There are 3.3 volt and 5 volt pins. But these are for supply output from USB to your board, not a select-able Rx/Tx voltage. The chip is a 3.3 volt chip with a build in regulator. So one must assume that the TX/Rx outputs are 3.3 v. But the datasheet does not explicitly state this. I would consider a voltage divider for incoming 5 volt TTL.

**Q: Does this work okay with Windows 10?**
A: Yes, never had an issue.

**Q: Where is the driver for win 10?**
A: You can download the corresponding driver from this link: https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

**Q: Got these to connect to a 4800 baud gps. driver loaded fine, connec gnd-gnd, gps + to rxd. rx led flashes, win10 visualgps just displays trash, ideas?**
A: Try a lower baud baud rate. Usually “trash” output means the baud rate is incorrect.

### ⭐⭐⭐⭐⭐ Interfaces directly to a microcontroller
*by J***N on March 21, 2023*

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.
