Delivery is conducted every day at work hours Stock march 31st = 20pcs Size: 31mm x 22mm; Play chip: Ne555; 5v-15vdc. When power supply is 5v, the output current can be 15ma around;When 12v power supply, the output current can 35ma around; Current input: > = 100ma Output amplitude: 4.2v v-pp to 11.4v v-pp. (Different input voltage, the output amplitude will be different) Maximum output current: > = 15ma (5v power supply, v-pp greater than 50%), > = 35ma (12v power supply, v-pp greater than 50%) Output with led indicator (low level, led will on; high level, led will off; low frequency, the led flashes); The output frequency range is selectable: Lf file: 1hz ~ 50hz If file: 50hz ~ 1khz High-frequency file: 1khz ~ 10khz Hf file: 10khz ~ 200khz The output duty cycle can fine-tune;Duty cycle and frequency is not separately adjustable;Adjustering the duty cycle will change the frequency; The output frequency is adjustable: Period t = 0.7 (ra + 2 rb) c Ra, rb is 0-10k adjustable; Low profile when c = 0.001uf; If stalls c = 0.1uf; High-frequency file c = 1uf; Hf stalls c = 100uf; So buyers can calculate the frequency of the waveform Application: As a square wave signal generator, generates a square wave signal used for experimental development. Used to drive a stepper motor for generating a square wave drive signal General adjustable pulse for mcu. General adjustable pulse, to control circuitry associated.\ =============================== Bro, Please be very careful to read yes, By buying, Mr. buyer has agreed to the terms and provisions of the store below. "The delivery was made by the third party (Jne / tiki) And the trouble with the return process is also the expensive budget, To make sure the goods that are Mr. buy function well, All electronics (Except the one sealed from the factory.)
