DIY Kits 1Hz-50MHz Crystal Oscillator frekvencia számláló digitális LED PIC

DIY Kits 1Hz-50MHz Crystal Oscillator Frequency Counter Meter Digital LED PIC ATColor: Red
SIze: 8 x 5.4cm
Suitable For:
Crystal measure (4M, 16M crystal)
Crystal measure (20M, 11.0592M crystal)FeaturesThis 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 manual1. 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 frequencyPacking Included1 x 1Hz-50MHz frequency meter (DIY kits, not assembled)
