At first glance it looks quite versatile. However, is 70mA enough to power the DW module? How large a capacitor will be needed?

I was looking through the docs on the plane. I noticed on the DW1000 datasheet, p10 table 4 it talks about 3.3V power being 30mA, but it has an asterisk that I don't understand.
