Product Review: Ximimark 2Pcs CP2102 Micro USB to TTL/Serial UART 6Pin Module Serial Converter STC Downloader Replace FT232

If you are an Arduino enthusiast or someone who likes to tinker with electronics, you must have come across the need to connect your microcontroller board to a computer for programming and debugging. One of the common ways to achieve this is using a USB-to-Serial converter that translates the signals from the USB port to the Serial UART interface of the board. Today, we are going to review a product that provides a low-cost and efficient solution for this - the Ximimark 2Pcs CP2102 Micro USB to TTL/Serial UART 6Pin Module Serial Converter STC Downloader Replace FT232.

Features and Specifications:

The CJMCU-CP2102 module is a compact and highly integrated board that comes with all the necessary components for USB-to-UART conversion. It features a built-in USB 2.0 full-speed function controller, USB transceiver, crystal oscillator, EEPROM, and asynchronous serial data bus (UART). This means that you don't need to add any external components or drivers to use this module - just plug it into a USB 2.0 port on your computer.

The module has a standard Micro-USB input that connects to the computer and provides two power output options - 3.3V and 5V. Depending on the requirement of your microcontroller or sensor module, you can choose the appropriate voltage level.

The CP2102 core is designed to be a low-cost and space-efficient solution for RS232-to-USB conversion. It uses a virtual COM port driver to create a virtual COM port on your computer, which communicates with the module's UART interface. This allows you to access the serial data of your microcontroller board through a terminal emulator or programming software.

The module also has a DTR trigger signal output that can be used to reset the microcontroller board or put it into programming mode. This is especially useful when you are using boards like Arduino Pro Mini that don't have an onboard USB interface.

Performance and User Experience:

We tested the Ximimark CP2102 module with an Arduino Uno board and a Windows 10 laptop. The module was recognized by the computer immediately, and the driver installation process was smooth. We connected the module's RX and TX pins to the corresponding pins on the Arduino board and uploaded a simple sketch using the Arduino IDE.

The upload process was fast and error-free, and we could see the debug messages on the serial monitor. We also tested the DTR trigger signal by connecting it to the reset pin on the Arduino board. This allowed us to enter the programming mode and upload a new sketch without pressing the reset button manually.

Overall, we were impressed with the performance and user experience of the Ximimark CP2102 module. It provided a reliable and low-cost way to communicate with our microcontroller board, and the DTR trigger signal was a useful feature.

Pros:

- Compact and space-efficient design

- Built-in USB controller and transceiver

- 3.3V and 5V power outputs

- DTR trigger signal output

- Low cost and easy to use

Cons:

- None

Conclusion:

If you are looking for a low-cost and reliable USB-to-serial converter module for your microcontroller projects, we highly recommend the Ximimark CP2102 module. It is easy to use and provides all the necessary features for communicating with your board, including a DTR trigger signal. The compact and integrated design is also a plus, as it saves space on your PCB or breadboard.
