How to upload to arduino nano via chinese ch340g usb to ttl converter?

Development Tools IDE 1.x

Hello ,

As the title states I would like to know how to upload to my nano using a usb to ttl converter because the micro usb port broke off.I have wired the nano as follows:
Nano Converter
RX > TX
TX > RX
5V > 5V
GND > GND
but nothing happens except that the nano turns on.

Thanks in advance,
Hristo

Nano Converter
RX > TX
TX > RX
5V > 5V
GND > GND

RST > DTR

If no DTR, you will have to use the reset button. Hold and release after the sketch is compiled.

You appear to be a pin missing.

A picture of the actual converter would be nice as there are a few variations.
I trust you already installed the CH340 driver on its own.

This is the converter I have tried holding down the reset button but still it doesn't work

Press Reset on the Nano when the IDE shows "compiled xxx of 32xxx bytes".

It can be easier to see the timing of it if you select File:Preferences and turn on Verbose Output.

Or, press & Hold reset down, release when you see the message.

Or get an USB/TTL adapter that has the DTR broken out for you.
These two both work well

Doesn't look like one I have seen before.
All the ones I have also have DTR and CTS.

With that you would have to do the reset trick but sometimes timing can be a little awkward.
