Special Features

  • 【Adjustable Square Wave Generator】 10-bit resolution; 1Hz to 200kHz frequency range; 2% to 98% duty cycle control; LED output status indicator; Compatible with Arduino, Raspberry Pi, and STM32
  • 【High Output Current for Stepper Motor Control】 35mA output current at 12V; 15mA at 5V; Suitable for driving stepper motor drivers; Low power consumption; Stable performance under varying input voltages
  • 【Precise Frequency and Duty Cycle Adjustment】 Frequency controlled via potentiometer (RA+RB: 0–10kΩ); Duty cycle adjustment affects frequency due to shared RC network; No calibration drift; Easy to set using formula T=0.7×(RA+2RB)×C
  • 【Compact Design with Clear Visual back】 31mm × 22mm size; LED indicates output level (on=low, off=high, blink=low frequency); Simple setup; Ideal for lab experiments and prototyping
  • 【Reliable Performance in General Applications】 No high-voltage support (>50V not recommended); Stable operation from 5V to 15V DC; Low interference design; Easy integration into circuits and microcontroller projects
