Multiple Channel Monitoring: Should be able to measure multiple electrical circuits.
Accurate Measurements: Should be able to accurately display voltage, current, and power to a very high degree.
Real-time Data: Should display data instantaneously. Data latency must be reduced such that the displayed data is relevant and specific to the time period.
Optimized Energy Efficiency: Given that the board will not require external power supplies, the power consumption of the board itself must be regulated and accounted for.
