60MHz Frequency Meter / Counter 10Hz to 60MHz

Posted on Feb 7, 2014

This project is nice and small frequency counter that reads frequency from 1 Hz to 50 MHz that I have modified from original designed by Weeder Technologies . I have designed new PCB to fit with 16X1 LCD and change source code for compatible with new small PCB Specifications - Auto-ranging with floating decimal point. - Up to 7 digits displayed on 1X16 LCD. - Auto-adjusting gate speed (0.1 sec to 1 sec). - Microcontroller-based circuitry provides for simplicity, ease of assembly, and highly stable readout. - Sensitivity approximately 100 mV RMS (100 Hz to 2 MHz), 800 mV RMS @ 50 MHz. - Input overload protected.

LCD display is connected to PCB by 16-PIN male & female header and is easily detachable from the main board. 16-PIN Male Header must be soldered to LCD display. 16-PIN Female Header must be soldered to PCB.
