The versatile OSHW Mini MCU-Link debug probe #Embedded #Development #Debug
Who needs a debug probe, if you have printf()? If doing serious development, you most likely want a hardware debug probe. Erich Styger dives into the subject:
We at the HSLU IET use different hardware, boards and kits, and for many of the classroom equipment it is very useful to have the debug probe embedded on the target board: less cables, easier to use. For this we have developed a new Open Source Hardware (OSHW) debug probe in KiCad which can used in different ways: as external debug probe, integrated and soldered on top of the target board, or fully integrated and embedded into a custom design.
The goal was to make it open, smaller and versatile:
Open Source Hardware design with KiCad
Binary firmware compatibility with MCU-Link (NXP 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
3D printable enclosure
BOM with assembly costs: ~$12/piece for 100 units (e.g. PCBWay), and more

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
