SUMMARY

The discussion centers on the activation issues faced by users of the AZDelivery AZ-MEGA2560-Board Bundle, specifically the Arduino Mega 2560. Users report encountering serial communication errors with AVRDUDE, indicating that the software cannot establish a connection with the board over COM3. The primary solution suggested is to install the Windows CH340 driver, which is necessary for proper communication between the AZDelivery boards and Windows operating systems. Users are encouraged to seek further assistance on Arduino forums if issues persist.

PREREQUISITES
  • Understanding of Arduino IDE and its functionalities
  • Familiarity with AVRDUDE command-line tool
  • Knowledge of Windows driver installation, specifically CH340 driver
  • Basic troubleshooting skills for serial communication issues
NEXT STEPS
  • Install the CH340 driver for Windows to enable communication with AZDelivery boards
  • Research common AVRDUDE commands and their usage for troubleshooting
  • Explore Arduino forums for additional support and troubleshooting tips
  • Learn about differences between original and clone Arduino boards
USEFUL FOR

This discussion is beneficial for hobbyists, electronics enthusiasts, and developers working with Arduino Mega 2560 boards, particularly those using AZDelivery products and facing serial communication issues on Windows.

Failure to be able to activate Arduino Mega 2650
hi; i purchased 3 of these,

AZDelivery 3 x AZ-MEGA2560-Board Bundle with Prototype Shield​

and each is reporting the error message below.

I have triple checked every aspect of the set up and all seems in order, cable devices port, board reburn bootloader et al . I have substituted an arduino uno and it works fine; could you help please
Thanks
Martyn

Technology news on Phys.org
It’s likely an upload/serial-port error on Windows, not a code problem. In plain English, AVRDUDE can’t talk to the board over COM3.

You might need a windows CH340 driver to talk to the card. Apparently AZ cards need that to interact with Windows.

There are other possible issues too. You should be able to find help on Arduino forums. I don’t think many members here work with these devices.
 
Can you get the boards working through the Arduino IDE?
What command are you using for AVRDUDE?
 
thanks, it is viewing the CH340; I've pretty much tried everything; giving up now; have acquired original - v - clone
Thanks
Martyn
