The LPC2148 development board is a mighty board with an ATM7TDMI series microcontroller considered an old guy compared to Cortex ones. But still, these are widely used and are powerful. The Development board has some handy features installed. 12MHz crustal allowing to run the processor at full 60Mhz speed. Couple RS232 ports, VGA connector, PS/2 connector for keyboard or mouse, 20-pin JTAG, SD/MMC slot, USB B-type, 8 LEDs driven with a serial-in parallel-out shift register, 2×16 LCD, buzzer, audio jack with an amplifier, two programmable buttons, and 256Kb of I2C interfaced EEPROM. The microcontroller itself has 512KB of internal flash and 32+8KB of RAM. All ports are accessible, and any external hardware can be disconnected with jumpers. This is a great board for prototyping and end application.
