Amazing debugger / uploader

This debugger is fully supported by PlatformIO, which is more than what I was expecting.
I was able to connect, flash and debug, without much pain, replacing the J-Link mini EDU which nowadays seems incredibly hard to find.
I haven't tried with Arduino IDE, but not expecting bad surprises there.
So happy that everything works so flawlessly, I am going to buy an extra one.

P.S. a previous review was complaining about the adapter being Mini-USB and not Micro-USB. Mine is Micro-USB and I am more than happy as it's the same format used by J-Link mini EDU.
I don't know if the previous reviewer meant "I wanted USB-C".

Nice, revive arduino nano 33 BLE with this debugger

My arduino nano 33ble dead for some reason.
Can burn bootlodaer and revive with this debugger.
Just choose from native arduino IDE
Tools > Programmer > ARM CMSIS-DAP Compatible

Thanks for the great open source hardware and software!

I've been using this debugger for programming and debugging my Arduino Nano 33 BLE and SAMD boards. It's now one of my essential tools for working with microcontrollers. I'll definitely be buying another as soon as life returns to some semblance of normality.

To respond to the previous reviewers, my debugger came with the USB micro connector you wished for. I would have been perfectly happy with a mini, but micro is fine by me too.

An amazing litte SWD debug adapter for Cortex-M cores

The CMSIS-DAP adapter can, on lower demands, replace the partly quite expensive JTAG/SWD debug-adapters from Keil, Segger, ... very good. It run's a bit slower, supports only SWD, but is much cheaper.
I have tested this CMSIS-DAP adapter with multiple Cortex-M boards and am thrilled - extremely small, only 10 US-$ and sufficient functionality & performance. And in comparison of size unbeatable.
The only small drawback: the mini-USB connection - unfortunately no micro-USB ...

Great CMSIS-DAP SWD Debugger

I was successfully able to use this debugger in conjunction with EDBG (https://github.com/ataradov/edbg) to program an ATSAMD21 part. Everything worked like a charm! My only gripe is with the USB mini connector. USB mini cables are hard to come by nowadays. A USB micro connector would've been much better.
