IBDAP is a fully CMSIS-DAP compatible debug adapter. It provides vendor independent debug interface between your PC over USB and target ARM device over JTAG/SWD pins. You can do debugging functions like stepping, breakpoints, watch points and firmware download etc. It's fully supported by Keil, OpenOCD, GNU GDB, IAR and other commonly used debugging tools.


  • NXP LPC11U35FHI33/501 ARM Cortex M0 48Mhz processor
  • 64kB Flash, 12kB RAM, 2kB EEPROM
  • 1xUSART, 1xI2C, 2xSPI, 1xUSB2.0, 8xADC(10-bit), 26xGPIO
  • Armstart GNU gcc-arm and make implementation of CMSIS-DAP with source codes provided.
  • Supports mbed programming.


  • NordicSemi nRF51, nRF52
  • STM32 ARM Cortex-M series
  • Atmel ARM Cortex-M series
  • NXP ARM Cortex-M series
  • Freescale ARM Cortex-M series
  • Any microcontroller that supports CMSIS-DAP protocol

Besides being functioning as a JTAG/SWD debug probe, IBDAP could also be used as an mbed development board. It has an ARM Cortex M0 processor running at 48Mhz and has peripherals like UART, I2C, SPI, USB. It can be used in applications like USB audio devices, USB mouse/keyboards, USB mass storage devices, USB-TTL adapter device and many many more. It also has 10-bit high precision ADC peripherals which make IBDAP an ideal device for any sensor projects.
