Modular Power Supply -Signal Generator Moudle Board Highlights Generic Brand Signal Generator Moudle Board Description: It is used as square wave signal generator to generate square wave signal for experimental development. It is used to generate a square wave signal to drive a stepper motor driver. Generate adjustable pulse for MCU. Generate an adjustable pulse and control the associated circuit. Output with LED indication, whether the output is direct and clear. The output frequency range is optional, which makes the output frequency more continuously adjustable. The output duty cycle can be slightly adjusted. Duty cycle and frequency are not separately adjustable. The duty cycle will change the frequency. specification: Main chip: NE555 Input voltage: 5v-15v, when 5V power supply, the output current can be about 15mA; when the 12V power supply, the output current can be about 35mA; Input current: = 100mA Output amplitude: 4.2 v-pp to 11.4 v-pp. Maximum output current: =15mA (5V supply, v-pp over 50%), =35mA (12V supply, v-pp over 50%) Output frequency range Low frequency range: 1Hz~50Hz Frequency mid: 50Hz~1kHz Mid and high frequency: 1kHz to 10kHz High frequency range: 10kHz to 200kHz Adjustable output frequency; Cycle T = 0.7 (RA + 2rb) C RA and Rb are adjustable from 0 to 10 k; C = 0.001uF at low frequency; C = 0.1uF at intermediate frequency; Medium and high frequency C = 1uF; C=100uF at high frequency Size Chart: Szie: Approx. 56 x 60 x 5mm / 2.20 x 2.36 x 0.20inch Package includes: 1 Piece Signal Generator Note: Due to the light and screen setting difference, the the item\'s color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
