README

MCU-Link with KiCAD

This repository hosts different versions of the original NXP MCU-Link CMSIS-DAP debug probe as open source KiCAD versions. Both as standalone probe or integrated into your design.

Many thanks to Dario Scheuber and his work to make this project possible!

Background

This is the work of Dario Scheuber who created this debug probe as student at the Lucerne University of Applied Sciences and Arts at IET. The project was done under the guidance of Prof. Erich Styger.

See blog article on https://mcuoneclipse.com/2024/02/06/versatile-oshw-mini-mcu-link-debug-probe-external-on-board-or-embedded/ for additional details.

Features

This is an open hardware version of the NXP MCU-Link CMSIS-DAP debug probe, with following features and differences to the original MCU-Link:

  • Open hardware design with KiCad
  • Firmware compatibility with MCU-Link (LinkServer, CMSIS-DAP, ARM DAPLink)
  • Dual-Layer design for lower costs
  • USB-C connector instead of Micro-USB
  • USB-C connector usable to debug the LPC55S69
  • 30% smaller than the original MCU-Link
  • Firmware/boot push button instead of jumper
  • Micro connector for UART connection instead of pin header
  • Supports only 3.3V targets (no level shifters)
  • Standalone version as external debug probe
  • On-Board version: Solder external debug probe on your custom board (castellated pins)
  • Embedded version: copy-paste into your custom board KiCad design
  • BOM with assembly costs: ~$12/piece for 100 units
