Can't see Binghe Nano V3 in Arduino IDE

Other Hardware 3rd Party Boards
1

I bought these Nano V3 USB Board Binghe 3 Pcs Nano Module V3 with 328PB Chip Module CH340G Controller 5V/16MHz Type-C Interface 328PB-AU Microcontroller Compatible with Arduino: Amazon.co.uk: Business, Industry & Science

but when I plug them in, nothing is shown in my Arduino IDE (v2.3.6 on Windows 11)

I’ve installed the driver: Nanjing Qinheng Microelectronics Co., Ltd. but still no joy.

I’ve used the official hardware Uno 4 before and had no issues. Should I have used ‘official’ Nano?

What about bootloaders. Do I need to do something about that? I’m still a bit new to this :slight_smile:

Hi @circuit07. Please perform this experiment to check if Arduino IDE is able to detect the port of your boards:

  1. Disconnect the USB cable of the Arduino board from your computer.
  2. Select Tools > Port from the Arduino IDE menus.
  3. Take note of the ports (if any) listed in the menu.
  4. Close the Tools menu.
    :red_exclamation_mark: The ports list is only updated when the Tools menu is re-opened, so this step is essential.
  5. Connect the Arduino board to your computer with a USB cable.
  6. Select Tools > Port from the Arduino IDE menus. - If a new port is listed in the menu, that is the port of your Arduino board.

If you saw a new port appear at the last step, select that port from the Tools > Port menu, then also select Tools > Board > Arduino AVR Boards > Arduino Nano from the Arduino IDE menus, then try uploading a sketch to the board.

If this doesn't solve the problem, please reply here on this forum topic with the answers to the following questions:

  • While following those instructions, did you see a port in the Tools > Port menu at step (6) that was not present at step (3)?
  • If you did see a new port, was the upload successful after you selected that port?

Does it show in Windows device manager? It should show like below.

@circuit07

Have you soldered on the header pins?

Thanks @ptillisch for your detailed reply.

With nothing connected, Tools> Port showed COM4, but it was greyed-out

I restarted the IDE, connected my Nano and Tools> Port showed the same - greyed-out COM4

@sterretje, I had to select View> Drivers by type, to see the Ports:

The last 2 are the ones I added most recently. I’m not sure I need the 343cdc one, so I might try deleting that.

Where do you get your USB-SERIAL CH340 driver from? I couldn’t find it one

Hi @jim-p, I got a pack of 3 Nanos. I have soldered the pins on one of the Nano’s, but the one I am using now for testing I haven’t soldered at all. There’s another one still in the packet.

Just to be clear, the PWR LED comes on, and the LED marked L is flashing at 1Hz

Because you don't see the port (as shown in the above) my conclusion is that your board is not detected; the output only shows the driver and USB ports that use that driver. With a disconnected board I see the below.

The CH341 driver is universal for a number of CH34x ICs. This is the preferred driver in case you have problems: Nanjing Qinheng Microelectronics Co., Ltd.; see Port monitor error: command 'open' failed: Invalid serial port. Could not connect to COM serial port - #49 by ptillisch.
Note that I don't have problems with my boards that use the CH340 and I'm using the latest driver. There have been issues with fake CH340 chips; does the CH340 on your board have a print on it? It's the chip on the bottom of the board. Can you take a clear photo and post it here.

That is the driver I have, although it’s version 3.9

It works! I tried a different USB cable and now it is all working. Thanks for all your help
