Design requirements

• Precise, easy calibration, reduced size, Current and Voltage measuring system
• Modular communication module: XBEE (jNode?, Etherner?, CAN?)
• Load ON/OFF or dimmer (10-12A Triac)
• Integrated 220V to 9V-5V power supply (ex. 220 to USB chargers)
• Optional: RGB LED / LCD for feedback
