Dccduino Uploading Problems

Development Tools IDE 1.x
1

I've recently bought an "UNO R3" from here: Geekcreit UNO R3.

I believe it is a Dccduino clone from the reviews and the look of the board. When I try to upload any code it stays stuck on "Uploading" for a while; then results in the below error message. The board shows up as a COM port and doing some research, these are the drivers I needed to install: CH341SER Drivers. Still not working.

I've tried changing the COM port number and baud rate. Neither have done anything to fix my problem. I've also tried the loopback test. When I type something into the "Serial Monitor" and hit send, the "RX" and "TX" leds flash, but I don't see any response in the monitor itself.

I've tried everything I could find online to fix the problem, with no luck. I'm thinking the board may have come defective. If anyone has any other ideas of what I can try, help would be very much appreciated.

Is your board recognized in Windows?

3

If you mean as a device with a COM port, yes.

4

Looks like it is a good product based on the reviews.

I guess try another cable.

Or another PC.

5

My laptop is able to connect and upload code to my other Arduinos (UNO and Nano); forgot to mention that.

I will try another pc and cable.

Also avoid USB 3.0 ports and cables.

And USB hubs should have thier OWN POWER.

You neglected to mention which OS you were using but if its win 8 or above then turn off driver enforcement for the CH340/341 drivers as they may on occasion look like they installed but in fact might have partially failed.
