Programming Nextion LCD Without SD Card

Hello everyone, I bought a Nextion Touch LCD. It's nice but uploading code with an SD card? Come on...we are in 2017. Just buy a USB TTL adapter (it is cheaper than an SD card by the way) and connect 5V and Ground to your LCD, then change the RX-TX connections opposite like this:

USB ---- TTL NEXTION

• 5V ---- 5V

• GND ---- GND

• RX ---- TX

• TX ---- RX

Connect it to your PC, then open Nextion Editor and choose one of the examples:

Press the "upload" button.

Then press "GO".

And it starts to upload.

Second step: Communicate it with Arduino UNO. Check out my next project.
