PIC28 PIN LCD RS232 PROJECT BOARD
The PIC 28-Pin LCD RS232 Project Board is a PIC microcontroller development board with LCD display and RS232 interface for learning and embedded projects.
The PIC 28-Pin LCD RS232 Project Board is a compact and versatile development board designed for 28-pin PIC microcontrollers such as PIC16F877, PIC16F84A, and similar MCUs. It provides an easy-to-use platform for learning, prototyping, and experimenting with LCD displays and serial communication.
Key features include:
-
4-bit LCD interface for displaying text and numeric data.
-
RS232 serial communication port for connecting to PCs or other devices.
-
All I/O pins broken out for LEDs, switches, sensors, relays, and other modules.
-
Onboard crystal oscillator, reset circuitry, and power regulation for stable operation.
-
ICSP support for in-circuit programming of the PIC microcontroller.
The board is ideal for students, educators, and hobbyists for building interactive embedded projects, serial communication experiments, automation systems, and robotics applications. Its compact design and easy interface make it suitable for both learning and advanced experimentation.
