NE555 Signal Generator Square Wave Pulse Frequency Adjustable Module 1~200KHz:
$3

Product parameters:
Chip: NE555Input voltage: DC5-15V (When 5V is supplied, the output current is about 15MA. When 12V is supplied, the output current is about 35MA.)Input current: ≥100MAOutput amplitude: 4.2V V-PP to 11.4V V-PP input voltage is different, the output amplitude is also different.Output current: 5V power supply, ≥15MA.12V power supply when V-PP is greater than 50%, ≥35MA when V-PP is greater than 50%.PCB specification: 37*33mm, thickness 1.6mmPCB material: FR-4 full glass fiber boardWeight: 10g
Features:1. Output plus LED indication, LED light at low level, LED off at high level, LED blinks at low frequency.2. The output frequency range is optional, and the output frequency and duty cycle are continuously adjustable:Low frequency range: 1Hz~50Hz Medium frequency range: 50Hz~1KhzHigh frequency range: 1Khz ~10Khz High frequency range: 10Khz ~200KhzTip: The precision adjustable resistor VR1 on the board regulates the duty cycle and VR2 adjusts the frequency.3. The output frequency range is adjustable:Cycle T=0.7(RA+2RB)C, VR1 and VR2 on the board are 0-10K precision adjustable resistance:C=102 (0.001UF) in low frequency range; C=104 (0.1UF) in medium frequency range; C=105 (1UF) in medium/high frequency range; C=100UF in high frequency range.Capacitance capacity determines the frequency range and buyers need to adjust based on their own calculations.
Product use range:
1. For square wave signal generators, generate square wave signals for experimental use.2. Used to generate a square wave signal that drives a stepper motor driver.3. Generate adjustable pulses for use by the MCU.4. Produce adjustable pulses, control related circuits.5. Use MCU learning, electronic competitions, product development, taxi meter, graduation design, etc.
Note: 1. This product is not a precision circuit and is not suitable for applications where high accuracy is required.2. The use of this product must have relevant electronic knowledge. Input voltage is too high or operation errors and other factors can damage the module. Please exercise caution.
