1 DC Supply
The AXIOM Beta developer kits ship with 5V DC power supply.
AXIOM Beta takes two 5V inputs (1x Microzed, 1x rest of electronics) and together draws 4A max, power consumption depends on operation and is in the 10-20 W range typically.
2 DC/DC Converter
Two 5V 2.5A output converters should be suitable.
3 Batteries
With batteries it is a convenient feature being able to:
- measure power consumption (AXIOM Beta does that already)
- estimate time left for operation (AXIOM Beta measures voltages - it still requires an algorithmn that turns the discharge curve into a time estimate)
- set low voltage warning level
