Power Supply
The CPU_42A-V1 board can be powered via either of the USB plugs (5 V); however, there is a current limit that
can be drawn from the host PC through USB. If the CPU_42A-V1 board is used to drive other satellite cards e.g.
MOT_GPDLV-V2 and the total system current required exceeds 500 mA, then the CPU_42A-V1 board needs to
be powered by the satellite cards. These satellite cards support external power supply.
The typical current drawn by the CPU board without any satellite cards connected is about 170 mA (@5 V).
For powering the board through an USB interface, connect the USB cable provided with the kit to either of the
Micro-USB connector on board as shown in Figure 3.
