First, the scope of application of this module: 1. It is used as a square wave signal generator to generate square wave signals for experimental development and use. 2. Used to generate a square wave signal that drives a stepper motor driver. 3. Generate adjustable pulses for use by the MCU. 4. Generate adjustable pulses to control the associated circuitry. Second, a brief explanation: 1, size: 3.1CM*2.2CM 1, the main chip: NE555; 2. Input voltage: 5V-15VDC. For 5V supply, the output current can be around 15MA; for 12V supply, the output current can be around 35MA.   3, the input current: ≥100MA 4, the output amplitude: 4.2V V-PP to 11.4V V-PP. (Depending on the input voltage, the output amplitude will be different) 5, the maximum output current: ≥ 15MA (5V power supply, V-PP greater than 50%), ≥ 35MA (12V power supply, V-PP greater than 50%)
