Power Usage
Practical measurement of a Gold specification modules worst case power usage, its CPU running at 400MHz and 128MB of memory clocked at 133MHz, gives a current consumption of 210mA at 3.3V (0.7W) . Slowing the CPU and using the Digital Voltage Scaling(DVS) system can substantialy reduce this. In addition Linux allows for complete suspend to RAM which can reduce standby power usage to very low levels.
This does not account for any use of the output power supply (up to 400mA@3.3V)
All figures are subject to a 1% measurement accuracy and are for guidance purposes only.
