Máy tạo tín hiệu sóng Ne555

I. scope of application of this module:
- to be used as a square wave signal generator to generate square wave signals for experimental development.
- square wave signal used to generate a driver of a stepping motor drive.
- generate adjustable pulses for MCU use.
- generating adjustable pulses to control the associated circuits.

Ii. brief description:
- size: 2.9 cmx3.6 cm, fixed hole distance 22.5x30.5 mm
- main chips: NE555;
- input voltage: 5V - 15VDC.The output current can be around 15MA when 5v is supplied; 12V is supplied
The output current can be around 35 ma;
- module weight: 10 g;
- input current: 100MA
- output range: 4.2 V V-PP to 11.4 V-PP. (Depending on the input voltage, the output range will vary)
- output current: 15MA (5V power supply, V-PP greater than 50%), 35MA (12V power supply, V-PP greater than 50%
Time)

Three characteristics of advantage:
- output with LED indicator, whether or not output is directly specified (low level LED quantity, high level LED extinction, low frequency LED
Flashing);
- the output frequency range file is optional (on short circuit cap sleeve), making output frequency more continuous adjustable;
Low frequency file: 1Hz~50Hz
Median: 50Hz~1kHz
Medium high frequency (hf) file: 1KHz~10kHz
Hf file: 10kHz~200kHz


- the output occupancy ratio can be fine-tuned, the occupancy ratio and frequency are not adjustable separately, and the adjustment of the occupancy ratio changes frequency
Rate; if required, the ratio




- adjustable output frequency;


Cycle t = 0.7 (RA+2RB) C
Ra, RB is adjustable from 0 to 10K;
Low frequency file C = 0.001 uf;
Mid-Frequency file C = 0.1 uf;
Medium high frequency (hf) file C = 1UF;
High frequency file C = 100UF, so frequency buyers of waveforms can calculate them themselves.
