1Hz-50MHz Crystal Oscillator Frequency Counter Tester DIY Kit 5 Digits High precision LED Digital Frequency Meter Module

Color: Red SIze: 8 x 5.4cm Suitable For: Crystal measure (4M, 16M crystal) Crystal measure (20M, 11.0592M crystal) Features: This is a PIC microcontroller-based frequency meter, subtraction frequency is set with crystal measurement functions and programmable, five digital display, easy and intuitive, all using in-line components, the circuit is simple and easy to make 1. measurable frequency range of 1 Hz -50 MHz (1Hz-50MHz); 2. The most commonly used measure of the oscillation frequency of the crystal; 3. Five-digit precision resolution (eg 0.0050 kHz, 4.5765 MHz, 11.059 MHz); 4. Automatic range conversion, without human handover; 5. Programmable subtraction frequency setting, such as a transceiver for measuring equipment; 6. selectable power saving mode within 15 seconds if there is no significant change in the frequency automatically turn off the display; 7. You can use a common USB 5V interface, power supply, can also use an external DC power supply or 9V battery. 8. A small number of elements, all in-line components, installation is simple. Instruction manual: 1. All line elements, PCB printing press to the correct welding, 2. After welding is completed with a standard source input signal, 3. Adjust the yellow adjustable capacitor so that the display is equal to the value of the signal frequency Packing Included: 1 x 1Hz-50MHz frequency meter (DIY kits, not assembled)
