Designed to measure the frequency of oscillation of most crystal oscillators. Based on PIC microcontroller can measure the frequency of 1 Hz to 50 MHz.

 Five digits of precision, for example, kHz x.xxxx, MHz, or xx. xxx x.xxxx MHz. 

Require a 9v battery and 5.5mm barrel connector which I have on this site under Pixie Accessories

Designed to measure the frequency of oscillation of most crystal oscillators. price/$12.50




Optional mode of power-saving: can automatically convert the display if the frequency does not change significantly in 15 seconds 

A very small number of components: a PIC16F628, 5, 7-segment LED screens, a 20 MHz crystal, and some resistors 

Material: PCB;. Frequency range: 1 Hz-50 MHz 

Glass Test Range: 4 KHz-48 KHz 

Built Item Size: 8 * 5.5 * 0.7 cm / 3.2 * 2.2 * 0.3 inches 

List package: 1 * Frequency Counter

This is a kit and needs to be soldered
