Once the board type is changed, from UNO to NANO, select the ' BOOT-LOADER' option from the tools menu. Once the example is uploaded, Change the Board type from Aruino UNO to Arduino NANO, keeping the rest settings intact. Once the above mentioned settings are copied on your IDE, upload the code on your master UNO. Step 4: Upload the ArduinoISP code on Master UNO under tools menu, port option, select ( your com port number) option from the list.ģ.under tools menu, Programmer option, select ' Arduino as ISP' option from the list.

under tools menu, board option, select the ARDUINO UNO option from the list.Ģ. Make the connections on arduino uno to nano in the following manner.Ĭonnection diagram and ICP Pin out attached.įrom the file menu, under examples, select ArduinoISP example.ġ. We will use Master Slave Serial Peripheral Interfacing (S.P.I.) method to bootload the arduino board. So you would require a few things before we bootload this nano Sometimes the clone arduinos are just copy of hardware and they miss to load the arduino bootloader into the ATmega328p,

If all the above steps are not working for you, that means your Clone Nano is missing the Boot-Loader.īootloader is what makes this ATmega328p chip what we are familiar with as ' Arduino', Once the port option is available, try to upload the blink example from the IDE>File>Example>Basic>Blink, if the code is uploaded successfully, it means that you are good to go, your arduin nano clone is set successfully.

Now once you have installed the CH340 drivers, check if the IDE discovers your device, means the port option will now be available to select. This is official website, but it is in chinese, you can google CH340 drivers for alternative english website for downloading the CH340 drivers.ĭepending on your Operating System on computer, select the version x32 or 圆4 drivers, then click install. The arduino nano ( genuine) version, has a FTDI's FT232Rl serial communication chip, which is replaced with similar chinese version of serial communication chip called as CH340, which isnt recognized by our drivers, beacuse windows doesnt has this CH340 drivers preinstalled.
