    Yellow

    - This document describes the construction of small frequency counter with a cheap PIC microcontroller and a few seven-segment LED digits.
    - Frequency range 1 Hz ... 50 MHz
    - Five digits resolution (display for example x.xxxx kHz, x.xxxx MHz,
    or xx.xxx MHz)
    - Measuring signal amplitude can be up to 30 v
    - 4-40 m passive crystals can measure
    - Automatic range switching with different gate times
    - Optional addition or subtraction of a frequency offset (programmable)
    - Very low component count: a PIC 16F628, 5 7-segment LED displays, a 20MHz crystal and a few resistors
    - Optional (configurable) power-saving mode which automatically turns
    - The display off if the frequency didn't change significantly within 15seconds
    - USB 5V or DC5-12V power supply can be used

    Red

    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
