Power supply
There are multiple power supply options on the FRDM-KV31F. It can be powered from either of the
USB connectors, the V
IN
pin on the I/O header, DC Jack (not populated), or an off-board 1.71 V –3.6 V
supply from the 3.3 V pin on the I/O header. The USB, DC jack, and V
IN
supplies are regulated onboard
using a 3.3 V linear regulator to produce the main power supply. A DC-to-DC linear regulator is not
available in 3.3 V on the J20 Header. However, a direct supply to KV31 microcontroller is available.
The table below provides the operational details and requirements for the power supplies.
