### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works well for me.
  

*by M***Y on Reviewed in the United States on March 25, 2024*

All three units functioned well. At first, I had a problem with my old Windows 7 computer recognizing the device. I was able to upload a sketch to it, and once I had done that, then the computer located the proper device driver for it. Not sure how that worked, but it did. They all worked fine with a Windows 10 computer. I was able to run a few simple programs, including one emulating a USB keyboard.One thing to note, when writing a sketch to output to the UART, you must use serial1.begin() (and associated serial1.xxx functions) not serial.begin(); The USB port does NOT share the UART pins as is the case on a UNO. If you have code that writes to the USB port, the program will not run until you open the serial monitor. If you write to the UART, it will run regardless of whether you have anything connected to the USB port or UART pins, but the output will only go to the UART pins.

    Great value, but a few things to note about these modules: LEDs and USB troubles
  

*by R***. on Reviewed in the United States on March 4, 2024*

For the value these are great little Arduino compatible Leonardo Atmel32u4 boards.  I wish there were a schematic for them. Then I'd know that the LED typically on pin 13 is actually on pin 17, and a bonus LED on pin 30. (Thanks to other commenters for the heads up on that)  Another problem I ran into:  When programming these modules I got my LED blink test code to work then suddenly, without any warning, ~10 seconds later, I got an error message on my PC telling me that the device's USB had failed. Sure enough I couldn't download code to the module; however, I knew that the module didn't fail, it was still running running my LED blink code. The PC didn't recognize the device no matter what I did like unplug and plug it back in... it would make the USB connect and disconnect sounds, then display the error message again.  To solve this problem, at least this worked for me so it's worth trying,  connect to a different USB port on your PC, like I said, I have a USB hub; however that's not good enough to switch to a different one on the hub. You need to go to a completely different USB port on the computer... directly to the PC if possible. It should register this time without a problem, then, using the Arduino IDE, change the port number and it connected right up and I was able to program my modules again.  I speculate, but there could be an issue with the USB and hubs, other devices plugged into the hub, I don't know.  Anyway it's a great board at a great value, I plan to pick some more of these soon.

    Seamless integration with arduino IDE, no issues with header install. Good product, would buy again.
  

*by W***Y on Reviewed in the United States on July 30, 2022*

Does what it says on the tin. Make sure you use a good micro-usb cable! The first one I tried lying around the house didn't provide enough voltage, so it didn't boot correctly. However, in spite of the user error, the device booted well when I had a proper cable attached. I'm using it to drive an Adafruit trellis at the moment.
