This frequency counter DIY kit is easy to install and debug. Its frequency range is 1Hz-50MHz.
Features:
Designed to measure the oscillation frequency of most crystal oscillators.
Based on PIC microcontroller?￠ can measure frequency from 1Hz to 50MHz.
Five digits accuracy?￠ for example: x.xxxx kHz?￠ x.xxxx MHz?￠ or xx.xxx MHz.
Optional power-saving mode: can automatically turns the display off if the frequency didn't change significantly within 15 seconds.
General USB interface can be used for power supply?￠ external power supply or 9V battery also can be used.
Very low component count: a PIC 16F628?￠ 5 7-segment LED displays?￠ a 20-MHz crystal and a few resistors.
Simple construction?￠ compact design?￠ easy to install and debug.
