After about a month of planning and 2 weeks of work I've finally finished my 3rd NES portable. Its based off the old Hyperkin Retron 1. Featuring a 4.3 inch tft LCD, push button volume control, USB C charging port and it's powered off of 2 18650 2800mah batteries. The case was 3D printed with Prusament pristine white PLA. The audio amp is a PAM8403 and I used the DS1803 digipot with a push button input to increase and decrease the volume. I built the NES controller circuit using a 4021 shift register and some push buttons. A boost converter was used to send power to the screen and NES. The digpot and audio amplifier receive voltage through a 7805 linear regulator.
