Erich of MCU on Eclipse has posted an update on his open source tinyK20 project. We wrote about it previously:

Changes from the earlier version (see “tinyK20 Open Source ARM Debug/Universal Board – First Prototypes“):
1.Replaced the K20 crystal with one having a smaller footprint.
2.Added Micro SD card socket on the back (same socket as on the FRDM-K64F or FRDM-K22F).
3.Because SD cards can draw more than the 120 mA the K20 internal 3.3V provided, there is a footprint on the backside of the board to add an extra DC-DC converter.
4.Moved reset button and headers.
5.First version with transparent enclosure.
