Founded in 2014, Shenzhen Koroli Electronic Technology Co., Ltd. is a semiconductor agent and display solution provider; Koroli has been focusing on industrial control, LCD module, serial screen, 3.5-inch serial port smart screen   It is a diversified enterprise integrating semiconductor distribution, application and development.

The serial display is composed of three parts: display driver board, outer casing and LCD liquid crystal display; a set of display schemes by single-chip microcomputer or PLC with controller, the communication part of the display scheme is serial communication, USART serial port or SPI serial port, etc.

Microcontrollers (Microcontrollers) is an integrated circuit chip that uses a very large-scale integrated circuit technology to have a central processing unit CPU with data processing capability, random access memory RAM, read-only memory ROM, various I/O ports and interrupt systems, and timers. Functions such as a counter/counter (which may also include display driver circuits, pulse width modulation circuits, analog multiplexers, A/D converters, etc.) integrated into a small piece of silicon to form a small and complete microcomputer system in the industry The control field is widely used. From the 1980s, from the then 4-bit, 8-bit microcontroller, to the current 300M high-speed microcontroller
