send35510dan NT35510 4.0-inch LCD screen back panel

Overview

The screen
was obtained from Xianyu (a second-hand marketplace). It's a 4.0-inch, 480x800 resolution screen with an NT35510 main controller, using an 8080 parallel port 16-bit. I couldn't find detailed information...

the backlight boost
converter is a PT4110. The TFT_BL_PWM here isn't actually connected, meaning the backlight control isn't brought out from the socket. Therefore, R20 is a 10k resistor.

For the modules,

there's an ESP8266 and a WB3S (a custom module). I included them because the backplate is there, and leaving it empty felt wasteful.

I also made an adapter board to connect to the Zhengdian Atom socket.
This PCB is 60x100mm, using a 40P FPC. If you want to use it with the Zhengdian Atom F1 core board, you can modify the FPC yourself.
The drawing might not be very good, please excuse the poor quality.
That's all.

Design of a single bus single chip multi-machine communication system
Traditional multi-machine communication systems generally require four wires: 1. Power line; 2. Ground line; 3. Send signal line; 4. Receive signal line. However, for systems with a long distance betw

For the charging part of the emergency light design, I used the MAX745 charging chip from Maxim, which uses dual-loop control and a PWM operating frequency of 300kHz. The charger using this control ch
The analog signal is divided into two paths for signal processing!
I was bored and suddenly remembered a problem I encountered last year that was never solved: I have an analog signal that I want to split into two paths and use analog circuits with different function
