 50 MHz frequency counter 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.
