EEPROM
The EEPROM is at address 162 on I²C Bus 1. It contains 256 bytes of non-volatile rewritable memory
typically used by applications for storing configuration information.

Power Supply
The 5811 may be powered from a supply voltage range of 7 to 30 volts unregulated DC. The current
consumption depends on the modules fitted and other devices attached, and whether the VM-1 processor is
idle. There is also a regulated 5V output for powering external circuits.
Drawing a high current or using a high input supply voltage will cause high dissipation in the regulator
heatsink. The heatsink and regulator are positioned so that they can be attached to an external heatsink or
casing if neecessary. Note that the regulator tab and heatsink are connected to ground.
The application board will draw typically 100 – 150mA by itself.
The ethernet card draws approximately 80mA extra when fitted.
The QVGA display draws approximately 40mA extra when fitted.
