The LPCXpresso1769 board with CMSIS-DAP containing NXP's ARM Cortex-M3 microcontroller has been designed to make it as easy as possible to get started with Cortex-M3. The board is the successor of the original LPC1769 LPCXpresso board. The LPC1769 has 64 kB SRAM, 512 kB Flash, 4xUART, 3xI2C, SPI, 2xSSP, 2xCAN, PWM, USB 2.0 Device/Host/OTG, RTC, Ethernet, I2S. This updated version has several enhancements:


  • The debug interface is CMSIS-DAP compatible, meaning that it is supported by many development environments, including (but not limited to) LPCXpresso IDE, uVision from Keil/ARM, Embedded Workbench from IAR
  • The CMSIS-DAP debugger can be disabled with a jumper, allowing an external debugger to be connected (via a standard 10 pos Cortex debug connector)
  • The debug side can be removed in a simpler way than before (snap/break off), but note that it is not possible to connect the two parts again. After breaking off the debug side, we recommend using LPC-Link2 as the debug solution
  • RGB-LED has been added
  • ISP-enable push-button has been added
  • Reset push-button has been added
  • The pcb is a 4-layer design with better grounding and power supply layout, making the board better suited for integration
  • The overall board size is smaller, but the expansion pins (2x27 positions) are mechanically compatible with the original design - making the transition to this new version very smooth


  • Processor: NXP's Cortex-M3 LPC1769 microcontroller in LQFP100 package
  • Flash: 512 kB
  • Data Memory: 64 kB
  • Clock Crystals: 12.000 MHz crystal for CPU
  • Dimensions: 35 x 105 mm
  • Power: 3.3V external powering, or 4.5-5.5V external powering, or from USB via CMSIS-DAP debug interface
  • Connectors: All relevant LPC1769 pins available on expansion connector (2x27 pin rows, 100 mil pitch, 900 mil between rows)
  • Other:
    • Embedded debug interface that is CMSIS-DAP compatible
    • Embedded debugger can be disabled to allow external debuggers to connect to the 10 pos Cortex debug connector
    • RGB-LED
    • ISP-enable push-button
    • Reset push-button
