ARM LPC2148 PROJECT BOARD
ARM LPC2148 based project board with LCD, ADC/DAC, serial communication, USB support, and expansion interfaces for embedded system development.
Description
The ARM LPC2148 Project Board is a powerful embedded development platform based on the NXP LPC2148 ARM7TDMI-S microcontroller, designed for learning, prototyping, and industrial project development. Featuring high performance with low power consumption, this board is ideal for students, engineers, and training institutes working on real-time embedded systems.
The project board integrates essential peripherals such as 16×2 LCD interface, keypad, LEDs, relays, ADC/DAC, UART (RS232), SPI, I²C, PWM, RTC, and USB 2.0 full-speed interface, allowing hands-on experience with a wide range of ARM-based applications. Onboard power regulation, crystal oscillator, and expansion headers make it easy to develop and test complex embedded projects efficiently.
