Arduino Compatibility
The I/O headers on the FRDM-K20D50M are arranged to allow compatibility with peripheral boards (known
as shields) that connect to Arduino™ and Arduino-compatible microcontroller boards. The outer rows of
pins (the even numbered pins) on the headers share the same mechanical spacing and placement as the I/O
headers on the Arduino Revision 3 (R3) standard.
