KOOBOOK 1Set 1Hz-50MHz Frequency Counter Meter Crystal Oscillator Digital Tester Meter DIY Kit 5-Digital LED Display

KOOBOOK #ad - The power supply can use a usb to 3. 5mm power cable, or you can directly input a 5-9V DC power supply at the - and + pads. You need to solder and assemble by yourself, the signal is input with the standard signal source, all the components are directly inserted, and the wire is printed correctly according to the PCB.

This is a pic microcontroller based on the frequency meter, with a crystal measurement function and programmable addition and subtraction frequency settings. Five digital display, all use of in-line components, easy and intuitive, the circuit is simple and easy to produce.

It can measure the frequency range from 1 hz to 50 megahertz 1Hz-50MHz, can measure the oscillation frequency of most common crystal oscillators, and measure equipment such as radio transceivers. After welding, and the yellow adjustable capacitor is adjusted to make the display value equal to the signal frequency.
