MKW40Z160 peripheral

functions

The USB-KW40Z development board includes two push buttons: one for a general purpose peripheral

function to assist in implementing targeted applications and the other dedicated to MKW40Z160 hardware

reset.

The board also include three LEDs, two for general purposes and the other as a Power-On indicator.

The application LEDs (D2 and D3) are connected not only with MKW40Z, they also share this connection

with the MK22FN512 MCU. You can isolate LEDs to remove or cut the trace over SH5 and SH6.
