Figure 2-1. FRDM-LS1012A power supplies

2.2.1 Primary power supply

The FRDM-LS1012A is powered through the CMSIS USB port (USB 2.0 Type Micro-
AB).

The total power required from USB port depends on devices used by an application.
Refer to the following table for an estimated power required by each of the board
interfaces.
