Power supply

There are multiple power supply options on the FRDM-KL43Z. It can be powered from either of the USB
connectors, the V

pin on the I/O header, an on-board coin cell battery, or an off-board 1.71–3.6 V supply from

the 3.3 V pin on the I/O header. The USB and V

supplies are regulated on-board using a 3.3 V linear regulator
