Description:

NE555 Pulse Module, adjustable frequency module.
Used as a square wave signal generator produces a square wave signal for the experimental development use.
Used to generate the square wave signal to drive a stepper motor drive.
Produce adjustable pulse for the MCU to use.
Generating adjustable pulse to control the associated circuits.

Specification:

Size: approx. 2.9 x 3.6cm; The fixed hole distance is 22.5mm and 30.5mm
The main chip: NE555
Input voltage: 5V-15VDC. 5V power supply, the output current can about 15MA; 12V power supply, the output current can be so 35MA;
Input Current: ≥100MA
Output amplitude: 4.2V V-PP to 11.4V V-PP (depending on the input voltage, the output amplitude is not the same)
Maximum output current: ≥15MA (5V power supply, V-PP greater than 50%); ≥35MA (12V power supply, V-PP greater than 50%)

Advantages:
-Output with LED indication, (low level: LED light on, high level: LED goes off, low frequency: LED flashes)
-Output frequency range grade optional continuously adjustable output frequency;
-Low frequency: 1Hz ~ 50Hz
-Middle frequency: 50Hz ~ 1kHz
-Medium-high frequency: 1KHz ~ 10kHz
-High-frequency: 10kHz ~ 200kHz

-the output frequency is adjustable
-Cycle T = 0.7(Ra + 2Rb)C
-Ra, Rb: 0-10K adjustable
-LF C = 0.001UF
- C = 0.1UF
-MID HF C = 1UF
-HF C = 100UF, so the waveform frequency buyers can own calculations.

Package Includes:

1 Piece NE555 Pulse Module
(5 Pack)

Note:

Color maybe slightly different due to different monitor.
The above size is measured by hand, please allow slightly difference. Thanks!
