3.1. Power supply
There are multiple power supply options on the FRDM-K64F board. It can be powered from either of the
USB connectors, the VIN pin on the I/O header, DC Jack (not populated), or an offboard 1.71–3.6 V supply
from the 3.3 V pin on the I/O header. The USB, DC jack, and VIN supplies are regulated onboard using a 3.3
V linear regulator to produce the main power supply. DC to DC linear regulator is not available in 3.3 V on
J20 Header, however a direct supply to K64 MCU is available. Table 1 provides the operational details and
requirements for the power supplies.
