1. applicable scope of this module:
1. Used as a square wave signal generator to generate square wave signals experimental development.
2. Used to generate square wave signals to drive stepper motor drivers.
3. Generate adjustable pulses MCU use.
4. Generate adjustable pulses to control related circuits.
2. Brief explanation:
1. Size: 3.1CM*2.2CM
1. Main chip: NE555;
2. Input voltage: 5V-15VDC.When powered by 5V, output current can be around 15mA; when powered by 12V, output current can be around 35mA
3. Input current: ≥100MA
4. Output amplitude: 4.2V V-PP to 11.4V V-PP. (Depending on input voltage, output amplitude will vary)
5. Output current: ≥15MA (5V power supply, when V-PP is greater than 50%), ≥35MA (12V power supply, when V-PP is greater than 50%)
Three advantages and features:
1. output has LED indicators; it's whether there's output (LED lights up at low level, LED turns off at high level, LED flashes at low frequency)
2. output frequency range level is optional, making output frequency more continuously adjustable;
Low frequency range: 1Hz~50Hz
Mid frequency range: 50Hz~1kHz
Medium and high frequency range: 1KHz~10kHz
High frequency range: 10kHz～200kHz
3. output duty cycle can be fine-tuned; duty cycle and frequency are not separately adjustable; adjusting duty cycle will change frequency
4. output frequency is adjustable;
Cycle=0.(RA+2RB)C
RA and are adjustable from 0-10K;
When in low-frequency mode, C=0.001UF;
In mid-frequency range, C=0.1UF;
Medium and high frequency C=1UF;
At high frequency setting C=100UF, so buyers can calculate waveform frequency themselves
Blue Board
1, onboard NE555 chip
2. Single-channel signal output, output duty cycle is about fifty percent square wave
3. Onboard adjustable resistor, adjusting resistance value can control output frequency
4. Onboard Power Indicator Light
5. Working voltage: 5~12V
6. Board size: 29(mm)x12(mm)
