This NE 555 square wave pulse generator module is a versatile tool for experimental development and various applications, such as driving stepper motors or providing an adjustable pulse for microcontroller (MCU) applications. The module features an NE 555 timer chip with jumpers and a potentiometer to fine-tune the frequency in four frequency ranges, and a second potentiometer to adjust the duty cycle. With an input voltage variable from 5V to 15V DC, the module draws approximately 15mA at 5v (35mA at 12v) and provides an output amplitude of 4.2V peak-to-peak to 11.4V peak-to-peak based on the supply voltage. The compact board measures only 31mm x 22mm (1.2 x 0.9), making it a convenient and cost-effective option for those seeking a reliable signal generator.
