Can't upload sketch to NyBoard

@Rongzhong Li Thanks for your help. I'm in France so if I can avoid a return it would be great. Should I try to go through the section 4.2.4 Burn the bootloader myself?

@Théo Cachet Yes, that's one option. If you have another Arduino, you can use it as an ISP. Or you may buy an inexpensive USBtiny ISP. If that all fails, I will send you a replacement. Sorry for the inconvenience and I will wait for any results from you.

@Rongzhong Li Oh, I didn't realized that thisn operations requires another Arduino. I don't have that. I actually know very little about hardware, I'm a ML researcher..

@Rongzhong Li

Thanks, I'll do that.

@Rongzhong Li @R L was there a solution that doesn't involve a personal setup? hate to waste ur time but i'm having the same issue.

@b c

Usually, it can be fixed by the following checks:

1. Install the CH340 driver;

• Mac

• Windows

2. Use the USB cable with the data function(the one included in the kit is good).

3. Select correct board (Arduino Uno) and serial port;

4. Connect the board and the programmer in the right pin order;

The above steps are covered in the user manual.

If the problem persists, send pictures/screenshots/videos to support@petoi.com or this forum. The more information provided, the easier to locate the problem.

Thanks, I tried the Arduino Uno board setting but it didn't change anything. Still same error. Here's copy of error msgs from Arduino IDE and attached screenshot from IDE with that option: ------------------------------------- Arduino: 1.8.18 (Mac OS X), Board: "Arduino Uno"

avrdude done. Thank you.

Yes, I think I did select the serial port when I was using the USB Adapter, and I selected the bluetooth port when using the Bluetooth adapter. See attached screenshot for serial case.
