The manufacturing of 200 tinyK20 board is progress, and I’m sharing pictures of it :-).

Learning from Failure: QFN Package Corner Problem
Every day, there is something new to learn. And having problems is always a good learning opportunity :-). Yesterday we were able to find a strange problem with our tinyK20 prototypes, just before we were about to send the design for manufacturing.

Thanks for all the feedback and suggestions so far on the tinyK20 project! I’m proud to present the next iteration of the universal microcontroller & debugger board based on the Freescale Kinetis K20 USB microcontroller:

In “tinyK20 Open Source ARM Debug/Universal Board – First Prototypes” I talked about using a USB thumb drive enclosure for the board, so here is the idea:

After the proof of concept phase (see “Proof of Concept: Open Source ARM SWD Debug and General Purpose Board“), the first prototypes are ready:

Proof of Concept: Open Source ARM SWD Debug and General Purpose Board
The Teensy is a great and tiny board (see “USB CDC with the Teensy 3.1 Board“), but it lacks real SWD/JTAG debugging capabilities (see “Hacking the Teensy V3.1 for SWD Debugging“). The Freescale Freedom boards are great, but for many applications too big, and have potentially too many components on it. So what about building a breadboard friendly tiny board which *has* SWD debugging ability *and* can be used to debug another boards?
So here is a working prototype based on the FRDM-K20D50M:
