### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    works fine with my arduinos
  

*by O***E on Reviewed in the United States on June 11, 2021*

I have a computer with an RS232 I/O.  I needed to monitor my Arduino's activity, but not using USB because if the computer disconnects the USB, the arduino resets.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Worked with Arduino Mega
  

*by B***N on Reviewed in the United States on February 13, 2023*

I've only tried one of the two (I only need one), but it worked as expected. As with all serial COM stuff, it took a minute for all of the USB-to-Serial and Arduino settings to be correct, but I was able to send data from my laptop to the Arduino through this. It worked exactly as expected and as needed.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Works, but not as pictured
  

*by S***L on Reviewed in the United States on August 1, 2020*

These work fine in circuit, but unlike the units pictured, the ones I received did not have mounting holes, which complicates my project. They did, however, helpfully come with some small jumper wires.
