Features:
* and
* Made of - materials, sturdy and practical
* The output has LED indication. When the LED is low, the LED goes out. When the for frequency is low, the LED flashes, which is more clear and convenient.
* The output for frequency range level is optional( with short circuit) to make the output for frequency more continuous.
* Generate, for pulse.
* Compact and practical design makes its work more stable.
* Wide range of application, suitable for a variety of equipment.

Specification:
Part name: for pulse for frequency generator module
Material: PCB circuit board
Color as shown
Size: 2.9 x 3.6 cm/1.14 x 1.42 inches
Fixing hole distance: 22.5 x 30.5mm/ 0.89 x 1.2in
Main chip: NE555
Input voltage: 5V~15VDC. When the for power supply is 5V, the output current can reach about 15mA; when the for power supply is 12V, the output current can reach about 35mA.
Weight: Weight: 10 g/0.35 oz(approx.)
Input current:>=100mA
Output amplitude: 4.2V V-PP to 11.4V V-PP.(Output amplitude will vary depending on input voltage)
Output current:≥15mA(5V power supply, V-PP greater than 50%),≥35mA(12V power supply, V-PP greater than 50%)
Output for frequency;
Low for frequency: 1Hz～50Hz
Intermediate for frequency: 50Hz～1kHz
Medium and high for frequency: 1KHz～10kHz
High for frequency: 10KHz～200KHz

Period T= 0.7(RA+ 2RB) C
RA and RB are 0~10K;
Low for frequency gear C=0.001UF;
Intermediate for frequency gear C=0.1UF;
Medium and high for frequency gear C=1UF;
At high for frequency, C=100UF, so the for frequency of the can be calculated by yourself.
