Specification Brand : Respicefinem BulletPoint1 : Extensive Frequency Range: : This NE555 Pulse Frequency Generator covers an output frequency range from 1Hz to 200kHz, including Low (1Hz-50Hz), Intermediate (50Hz-1kHz), Medium and High (1kHz-10kHz), and Frequency (10kHz-200kHz) bands BulletPoint2 : Flexible Adjustment Options: : Featuring adjustable RA and RB resistors (up to 10KΩ) and capacitors ranging from 0.001UF to 100UF, this module allows for fine-tuning of the output form's frequency and duty cycle. Users can easily calculate the period T = 0.7(RA + 2RB)C BulletPoint3 : Performance: : Designed with a compact and practical form factor, this generator delivers stable performance across its input voltage range of 5V to 15VDC. It provides output currents of 15mA at 5V and 35mA at 12V, ensuring consistent operations in various applications BulletPoint4 : User-Friendly Indicators: : Equipped with an LED indicator that visually shows the output frequency status, this module makes monitoring easier and more convenient. When the LED is off, the output is low; when it blinks, it indicates low-frequency output BulletPoint5 : Versatile Applications: : Ideal for educational purposes, hobbyist projects, or professional use, this pulse frequency generator is suitable for developing circuits that require adjustable square signals. Its wide applicability ensures it fits seamlessly into multiple setups ItemName : Respicefinem NE555 Pulse Frequency Generator Adjustable Duty Cycle Signal Module 1Hz-200kHz Output for Electronics Projects and Experiments ItemPackageDimensions_Height : 3 centimeters ItemPackageDimensions_Length : 12 centimeters ItemPackageDimensions_Width : 9 centimeters ItemTypeKeyword : pulse-generators Manufacturer : Respicefinem ModelNumber : Respicefinemkqpcngv9au PartNumber : Respicefinemkqpcngv9au ProductDescription : Spec: Item Type:Pulse Frequency Generator Size:2.9 x 3.6cm / 1.14 x 1.42in Fixing Hole Distance:22.5 x 30.5mm / 0.89 x 1.2in Main Chip:NE555 Input Voltage:5V~15VDC.When 5V is supplied, the output current can be around 15mA; when 12V is supplied, the output current can be around 35mA. Weight:Weight: 10 g / 0.35 oz(approx.) Input Current:>=100mA Output Amplitude:4.2V V-PP to 11.4V V-PP.
