In this week, I have soldered the circuit board and carefully tested the each part of the circuit for disconnection and other mistakes and corrected them. The booster voltage regulator circuit finally works properly and other part of the circuit works also as expected and I will start to program the firmware of the OLED to make it work properly as currently, it only can show the the whole screen light up.
As the screen can light up, I can do the next level of development for the real development.
