NE555 Multi-Channel Waveform Generator Module Sine Triangle Square Wave DIY Kits

NE555 multi-channel waveform generator electronic production kit training parts.

Power supply voltage: 6-12V DC voltage, 9V is recommended

Product Description:

NE555 multi-channel waveform generator can generate square wave, sawtooth wave, triangle wave and sine wave.

Choose a kind of waveform output by jumper, the circuit is simple and the operation is convenient.

In the circuit, D1 is an anti-power supply reverse diode, and C1 is a filter capacitor. IC1, R1, R2, and C2 form a square wave generator, the signal is output from pin 3 of IC1, and C3 is an anti-interference capacitor. The square wave output from the third pin of IC1 is divided by R3, R4, and C5 is coupled, and J1 can be short-circuited with a short block to output a square wave at the output. The other path is coupled with C3 through C4 and divided by C3, and the sawtooth waveform is formed by integrating circuit R5 and C7 and output by J2, and then by the next stage of integrating circuit R6 and C8, a triangular wave is formed and output from J3. After finally passing through R7, after being amplified by the amplifier circuit composed of C9, R8, Q2, and R9, it becomes a sine wave at the collector of Q2. R10, R11, and Q1 form an emitter follower amplifier circuit, and finally the signal is coupled to W1 through C10 to divide the voltage and output from the output terminal.
