5Pcs NE555 Pulse Generator 555 Timer Module Single-Channel Signal Output Adjustable Frequency Rectangular Wave Signal Generator for MCU Learning with Dupont Cable

Product Description

NE555 timer: NE555 timer is an integrated circuit chip, which is often used in timers, pulse generators and oscillator circuits. The 555 can be used as a delay device, trigger or start-up element in the circuit. 555 timer can work in three working modes: monostable mode, astable mode, bistable mode. Product introduction: Onboard NE555 chip, working voltage: 5~12V, output current 225 mA (MAX), rise/fall time 100 ns. Features: Single-channel signal output, the output duty cycle is about 50% of the waveform, the potentiometer adjusts the output frequency, the output frequency range is 5~2KHZ (changing the capacitor C1 can change the output frequency), the output voltage is equal to the input v…
