NE555 Frequency Adjustable Pulse Generator Module (OT3701)

Built-in chip NE555.A single channel output, square wave pulse generator module based on the ubiquitous NE555 timer IC.The module can be powered from a wide supply range (4.5 to 12V) and will produce a continuous square wave output between 15Hz and 24KHz, which can be adjusted with a built-in multi-turn potentiometer.Useful for applications where an approximate frequency clock source is required, such as for stepper motor tone generation, etc.Specifications:PCB color: BlueSupply voltage: 4.5 to 12VSupply current: 3mA at 5V VccMin freq (approx.): 15Hz 49% duty cycle at 5V VccMax freq (approx.): 24KHz 89.4% duty cycle at 5V VccOutput voltage: 4.5V at 5Vcc / 11.5V at 12VccSize: 29 (mm) x12 (mm)DimensionsLength: 2.9cmWidth: 1.2cmHeight: 1.2cm
