Voltage Amplifier Board: $29.00

This circuit board will take a minimum of 5 mV input and amplify it to a maximum output of 4 VDC (that is 800X!).  The gain (amplification) is adjusted with a Trim Pot located on the board (not shown on this version.  The maximum input to the board is 2VDC.  The minimum output that it can produce is around 25 mV.  The board requires 7.5 to 24V DC for operation.

Minimum Input:   5 mV      Maximum Input:   2 V
