Can't upload sketch to arduino nano

I am having issues uploading any sketches to the arduino nano i received today. I have looked through a lot of different troubleshooting posts that recommend a few different solutions but none of them work. To my knowledge, this is not a clone or knock-off chip either.

When uploading (even a nothing sketch), i receive the error:
avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x58
I have noticed in my device manager that it is showing up as "USB Serial" under "Other devices". Not sure if this is a problem.

Things I have tried:

  • Changing the processor from ATmega 328p to ATmega 328p(old bootloader)
  • re-burning the bootloader. This threw up errors too despite rewiring and following the diagram to a T:avrdude: Device signature = 0x000000 avrdude: Yikes! Invalid device signature.

Bare Nano, or you have circuits attached? Is the on board LED blinking?

Bare arduino

and the power led is stable green and there is a slow blinking red LED

Do you have the correct serial port and board type selected in the IDE upload tab?

I have board type as "arduino nano" and there is only 1 available com port being "COM1"

Is COM1 still visible when you unplug the Nano?


Then COM1 isn't the Nano, it's a native port on your PC.

Ah ok... Makes sense XD

But in that case, there is no other com port being displayed

You said it appears in the device manager. What information is shown there? Which com port? In the device manager, is the port shown as "working"? What OS do you have?


You have no PC driver installed for the serial chip on the Nano. Which serial chip does it have? Now we need a lot more information about the board...

Windows has a database of USB-serial chips that it will automatically install when they are attached. Not all chips are in the database, you have to manually install the drivers.

This is the product page on amazon.

It says the chip is this "CH340 chip".

Bingo. You have to download and install a driver.

Cool will do that :slight_smile: thanks for your help
