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

Description In the circuit D1 is the anti power diode and C1 is the filter capacitor IC1 R1 R2 and C2 form a square wave generator The signal is output from the three pins of IC1 and C3 is the anti interference capacitance The square wave output from the third pin of IC1 is coupled through R3 R4 partial voltage and C5 and the square wave can be output at the output end by shorting J1 with a short circuit block The other circuit passes through C4 coupling and C3 partial pressureThe sawtooth waveform formed by the integration circuit R5 and C7 is output by J2 and then the triangle wave formed by the integration circuit R6 and C8 is output from J3 After R7 C9 R8 Q2After the amplification circuit composed of R9 is amplified the Q2 collector becomes a sine wave R10 R11 and Q1 form an emitter following amplifier circuit and the final signal is output from the output terminal through C10 coupling W1 partial voltage Specifications Product name NE555 multi channel waveform generator DIY welding kitProduct model TJ 56 133Working voltage DC5 12VPCB size 52 45mmPackage Include 3x 1K ohm Color Ring Resistor1x 1M ohm Color Ring Resistor1x 4 7K ohm Color Ring Resistor3x 10K ohm Color Ring Resistor1x 15K ohm Color Ring Resistor2x 100K ohm Color Ring Resistor1x 0 01uF Monolithic Capacitor1x 0 01uF Ceramic Capacitor1x 0 1uF Monolithic Capacitor1x 0 1uF Ceramic Capacitor4x 0 047uF Ceramic Capacitor2x 4 7uF Electrolytic Capacitor1x 1N4007 Diode1x 50K ohm Adjustable Resi
