The hardware design welding work has been basically completed after many modifications, and we will introduce it from the smallest display unit.

At first, we needed to install multiple 1.9-inch displays on the machine to display simple counting information. I thought of T113-S3/RK3506G2 + XC6SLX for Linux framebuffer video cutting, and then sending it from lvds to multiple small displays, which only needs to maintain the Linux application.
We chose a cheap QFN48 small chip-->GW1NSR-LV4CQN48, which is QFN48 packaged and easy to design and weld. It has 4K LUTs that can fully meet micro applications, and it also has built-in 100MHz Cortex-M0 and 64Mbits HyperRAM. Input data from lvds and output from MCU I8080/MIPI LCD interface. LCD interface We have equipped with 30P MCU I8080 interface and 1.9" 170x320 8bits I8080 LCD screen. We also selected a 1.6" 400x400 12Pins 1Lane MIPI round LCD screen as a reserve. I have set up aWS2812B ambient light for it. A 24Pin OV5640 2Lanes MIPI camera interface is also reserved for future verification.
Another new version has been modified, and we have added a terminal 100R resistor to the input of the MIPI CSI camera according to the original FAE prompt.
We will prepare Kicad's design files later and they will be placed under https://github.com/eleclab-rpi/FPGA_GW1NSR_LV4_1.9-_LCD.
