Hi,
Customer could consider to refer TWR-K22F120M board or FRDM-K22F board about K02 chip application.
TWR-K22F120M board schematics and FRDM-K22F board schematics also provided.
In general, customer need to consider power supply circuit, debug interface and external refer clock source.
Customer also could refer <Kinetis Peripheral Module Quick Reference> document.
Wish it helps.
