Further comments

Starting with a 9V 700mAh battery, I created a potential divider to supply 5V to the screen because the NEXTION display uses a 5V voltage level. Similarly, the ESP8266 uses a 3.3V level so I cascaded another potential divider to give 3.3V from the 5V to the ESP8266. For the USART communication between the ESP8266 and the display, the voltage levels have to match so I used a PCA9306 level shifter to do that. I also added a RED LED as an indicator that the whole system is ON.

use esp32 or if you can find a way to create a board use the sesboard

Alright. Working on that.
