5.8 Arduino Compatibility
The I/O headers on the FRDM-KL05Z are arranged to allow compatibility with peripheral boards
(known as shields) that connect to Arduino™ and Arduino-compatible microcontroller boards. The
headers share the same mechanical spacing and placement as the I/O headers on the Arduino Revision
3 (R3) standard.
Refer to the FRDM-KL05Z Pinouts spreadsheet for a compatibility chart showing how all the functions
of the KL05Z signals on the I/O connectors map to the pin functions available on the Arduino Uno R3.
