40MHz Frequency Counter Module

  
The standard circuit will display directly in Hz (1MHz max), and there is a seperate on board divider that will allow you to display directly in KHz (approx 40MHz max). Becuase the display reads directly in Hz or KHz there is no need for decimal point switching and the associated complexity. There are no switches or controls, simply feed the signal into one of two inputs and you have a direct readout in Hz or KHz.
