[Lichuang Development Board] Chen E2’s game console

I don’t know why, but I have to open it with an editor to see the schematic diagram and PCB
. 1. Introduction
The main control used in this game console is GD32F450ZGT6, with a maximum frequency of 200MHz. The game console mainly has four function buttons, a reset button and a joystick button. Supports motor vibration, external 3.5mm headphone jack and 3W speakers. It can be powered by lithium batteries and is easy to carry.

三, Hardware design
The hardware part is similar to the official part and I won’t go into too much detail.
1. Main control: GD32F450ZGT6. This chip equipped with Lichuang development board has rich peripheral interfaces and many learning resources. Official website: https://lckfb.com/
2. Power module:
The external power supply is powered by a 3.7V lithium battery. The pressure chip uses MT3608L, which boosts 3.7V to 5V to power the Liangshan School development board. There is no long-press shutdown function and no charging function.
3. Reset button:
4. RGB ambient light:
The original intention of setting up this ambient light is that when I operate the joystick button, the joystick button twists in different directions, and the six RGB lamp beads display different colors, but I did not consider the light. The brightness of the beads is very strong, and it is placed next to the screen. After the code is implemented, it is a bit hard on the eyes to operate. I will just add a 3D shell to the game console later.

4. Follow-up plan
What you want to do in the future This game console draws a 3D shell and adds video playback functions to the software.
