Arduino Mega 265 and Overo WaterSTORM//Summit

Hi everyone, I am thinking of using Overo WaterSTORM//Summit as high-level controller and Arduino Mega 265 as low-level controller but am having doubts about whether the 5V pin on Mega is sufficient to power the Overo.

From Gumstixhttps://store.gumstix.com/index.php/products/215/, Summit can take in 3.5V to 5V which the 5V pin can supply without problem.

Originally Summit is powered up from a wall plug adapter that outputs 5V, 1200mA.

Based on this information, would it be ok to power Overo WaterSTORM//Summit from the 5V pin on Arduino Mega 265?

The 5V output is not for powering external equipment.

A few sensors drawing less than 100 mA in total, perhaps.

Thanks for the info Paul
