Tolerance of External Input Power Supply Voltage for the SparkFun OpenScale Board (SEN-13261)

Hello,

I am currently working with the SparkFun Open Scale (SEN-13261) board and I need some clarification regarding the input power voltage. Could anyone please provide information on the tolerance levels for the input power voltage that the Open Scale board can safely handle?

Operating Voltage: well regulated 5V DC

Operating Ampage: 80-100mA

Instability in power supply voltage will cause variations in weight.
