Low cost, 5-inch portable touchscreen with HDMI resolution of 485x840, button control, and lighting effects.

Low cost, 5-inch portable screen with touch HDMI, 485x840 resolution, button control, and lighting effects.

1. Demo video: https://www.bilibili.com/video/BV1eH4y1Q7CA/?spm_id_from=333.999.0.0
2. Actual effect:
 
3. I'm not very good at drawing the shell, so it just covers the screen. I've open-sourced the project, so everyone can modify it themselves.
4. Open source materials
5. Also open source a minimal F6P6 system with OLED and a 1.4-inch LCD screen.
I. Hardware Overview
1. Power supply: 5V->3V3->1V8
2. LCD backlight driver circuit
3. LTC8619C peripheral driver circuit
4. HPD insertion detection circuit
5. CW32 peripheral circuit
6. Button control circuit
7. W2812 lighting control circuit
8. Ch554G touch to USB circuit
II. Software Overview
1. Consult the LCD driver, GT911, and LTC8619C datasheets to understand key communication timings, register configuration details, and register configuration methods. 2.
 
RGB working modes: RGB666, RGB888, etc. The LTC8619C and LCD configurations must be identical; different modes have different pins. Carefully check the datasheets before hardware design.
 
3. LTC8619C EDID parameter configuration involves using EDID configuration tools and EDID reading software to configure various parameters suitable for driving the LCD, such as clock frequency, RGB timing, I2S audio configuration,
 
etc.

ESP32-C3 displays weather, time, and class schedule; 0.96-inch OLED screen.

This project, based on the ESP32-C3 core board, displays the local weather, current time, and today's class schedule. It uses a 0.96-inch OLED IIC driver. The PCB is very small, easily fitting in a pocket, effectively solving the problem of having to take out a phone to check which class is being held before class.

The battery uses a 3.7V lithium battery. The connecting studs are 2.5mm in diameter, and three screws are used with lengths of 4mm and 10mm (depending on the battery size). The keycaps need to be of this type.
 
Front and rear panel CAD drawings and program source code links will be sent after someone comments.
