Shared project from Teensy creator Paul Stoffregen on OSH Park:
Teensy 3.6 DIY Reference Board
A known good reference board for testing the MKL04 chip when building a DIY Teensy 3.6. Refer to this table for the differences between Teensy 3.6 and other models. The soldering friendly LQFP package (at least more friendly than BGA) is used on this board.
