LPC2138 ADVANCED TRAINER KIT
LPC2138 ARM7 based advanced trainer kit with LCD, ADC/DAC, serial communication, and onboard peripherals for embedded system learning and development.
The LPC2138 Advanced Trainer Kit is a feature-rich embedded development and learning platform based on the NXP LPC2138 ARM7TDMI-S microcontroller. Designed for advanced embedded system education and professional prototyping, this trainer kit provides hands-on experience with ARM architecture and real-time applications.
The kit includes essential onboard peripherals such as 16×2 LCD display, keypad, LEDs, relays, ADC, DAC, UART (RS232), SPI, I²C, PWM, RTC, and expansion headers. With a stable onboard power supply, crystal oscillator, and clearly labeled I/O connections, the LPC2138 trainer kit allows users to easily develop, test, and debug ARM-based applications for industrial control, automation, and embedded product development.
