Arduino Nano V3 and LCD 128x64 how to connect them

[kbm]

I bought Arduino Nano V3 with Atmega processor and LCX 128x64. I need to connect LCX to Nano like on this schematic:

On Arduino Nano Microcontroller there are outputs allowing to connect cables without soldering but LCD has no such output. To connect the cables to LCX they have to be soldering.
First question is there perhaps a way to connect the cables to LCX without soldering? LCX has only holes where you can insert the cable but the cable will fall out without soldering.
Second question, if there is no way to connect the cables to LCX without soldering, what solder do I need to buy?

You have to solder a 20-pin male header with the LCD display. An ordinary 40W soldering iron and solder lead will work. Then you can connect the LCD with the Arduino Nano using a breadboard and male to male breadboard jumper wires. If you want to give your project a smarter look, you can choose 128x128 RGB TFT display:

A bodge ive used is  long pin male headers through the holes  plugged into a  female header  on the other side of the board ,the plastic strip on the pins can be slid up and down to get things clamped tightly.then use male-female wires to connect the arduino to the display

Soldering isn't hard. Any solder for general electronics work with rosin core (NOT electricians soldering huge busbars etc) around 0.5mm to 1.0mm diameter will be fine. You'll only use a few cm of it for this, but of course it's handy to have some left over for later. One of the little plastic tubes with 15g or so of solder in a spiral inside will last a good while.

You can get a cheap simple electronics soldering iron for not much money almost anywhere, but the Pinecil is REALLY good, for not much money ($26 here):

Or on Amazon for a little bit more (but likely free shipping):

It's got a RISC-V processor inside and you can reprogram it if you want. But you don't have to :-)

Soldering isn't hard.

indeed its not,however adding headers to a nano aint really an ideal starting point,might want to  get a bit of 0.1" stripboard and some extra headers and get your technique dialed in first.

Yes, I will buy soldering.
