critical during the USB enumeration which occurs when plugging in a new device. During this phase the SPOT may only draw 20% (100mA) of its full power requirements. It is known that a SPOT with the demo sensor board requires more power than this during startup and therefore does not work on USB power alone. For the hardware configurations in the kit this is not an issue, but for custom configurations this constraint should be taken into account.
