The ARM7 Development Board comes with NXP’s LPC2148 microcontroller. The microcontroller can be programmed through the serial port using the on-chip serial bootloader. The board features various interfaces available on-board like LEDs, Push Buttons, Analog Input, Dual-RS232 port, EEPROM, Power Amplifier, USB connector, Buzzer, Character LCD and dedicated connectors to plug-in a Temperature Sensor, Distance measurement sensor, Accelerometer, micro SD Card and an XBEE wireless device. A JTAG connector is also provided to enable programming and debugging of the microcontroller. The board can be powered using an external power source like an adapter or can be powered using the USB port on the computer. The ARM7 Development board has been designed for optimal use of the peripherals on-chip and interfaces on-board to create a variety of applications.


  • An on-board NXP’s LPC2148 microcontroller with ARM7 architecture.
  • A power jack for an external power supply from 8 to 16V AC/DC.
  • Alternatively the board can be powered through the on-board USB connector.
  • A 16x2 Character LCD interface operating in 4-bit mode. A potentiometer to vary the contrast of Character LCD.
  • A 3.5mm audio jack to connect the D/A output of microcontroller to a speaker or headphones.
  • Standard JTAG connector to support programming/debugging of LPC2148 microcontroller.
  • An on-board crystal of 12MHz to clock the microcontroller to upto 60MHz with internal PLL.
  • A push button to hardware reset the MCU.
  • A push button used in combination with RESET button to enter ISP mode.
  • On-board buzzer with selectable input to generate various audio frequencies.
  • Two DB9 connectors to implement RS232 communication using the on-chip UART0 and UART1.
  • An on-board crystal of 32.768kHz and a battery backup circuit with battery holder for on-chip Real time Clock.
  • A socket to plug-in Digi’s 2.4GHz XBEE RF transceiver.
  • Four Push Buttons to provide digital input to selected GPIO pins of the microcontroller.
  • Eight on-board user programmable LEDs on selected GPIO pins with an option to disable them using a jumper.
  • A connector for 4x4 Keypad interface.
  • A connector to plug-in distance measurement sensors such as HCSR04 Ultrasonic Sensors*
  • An I2C based EEPROM.
  • Micro SD Card connector on-board
  • The microcontroller can be programmed using the on-chip serial bootloader using the RS232-0 port.
  • A socket to plug-in SPI based 3-axis accelerometer.
  • Variable Analog Input using potentiometer using one of the three user selectable channels.
  • Socket for interfacing temperature sensor such as LM35.
  • On-board USB connector interfaced to on-chip USB peripheral of LPC2148 for USB based communication.
  • A Breakout for all the pins present on the microcontroller.
  • A Well-documented top and bottom side for easy hardware troubleshooting.


  • The development board can be powered using the mini-USB connector on-board, hence removing the need for additional external power adapter.
  • You need a serial port on your workstation to flash the microcontroller. Most of the Laptops today do not come with a serial port. You can use a USB-Serial Converter in this case.
