PIC40 Pin 4-bit LCD RS232 Project Board
The PIC 40-Pin 4-Bit LCD RS232 Project Board is a PIC microcontroller development board with LCD interface and RS232 communication for embedded projects and learning.
The PIC 40-Pin 4-Bit LCD RS232 Project Board is a versatile development board designed for learning and prototyping with 40-pin PIC microcontrollers, such as PIC16F877A. It provides an easy-to-use platform for building embedded projects with LCD display and serial communication capabilities.
This project board features:
-
4-bit mode LCD interface for displaying text and data.
-
RS232 serial communication for connecting to PCs or other devices.
-
All I/O pins broken out for easy interfacing with LEDs, switches, sensors, relays, and motors.
-
Onboard power regulation, crystal oscillator, and reset circuitry for stable operation.
-
ICSP support for in-circuit programming of the PIC microcontroller.
Ideal for students, educators, hobbyists, and engineers, the board is widely used in academic labs, embedded system courses, industrial control experiments, and robotics projects. It allows users to build interactive display systems, communication projects, and automation demos efficiently.
