5.2 Power Requirements
EK-RA4M1 is designed for 3.3 V operation. This also means that 5 V PMOD devices cannot be used
together with the EK-RA4M1 unless they are powered separately.
The total current available from the LDO regulator for all connected circuits is 600 mA or less, depending on
the 5 V power source used.
5.2.1 Power Supply Options
EK-RA4M1 can be powered in several different ways as described in this section.
