Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module LCD Display 1Hz-150Khz 3.3V-30V PWM Board Module

2 Channel PWM Signal Genenrator Feature: Two independent PWM generators can control the frequency, duty cycle The wide frequency range, high accuracy Can serial communication First, the module description: Frequency is divided into three series: XXX (no comma): the smallest unit is 1Hz, the range 1Hz -999Hz XX. X (comma in ten): The minimum unit is 0.1 Khz; the range of 0.1 KHz -99.9 KHz X.X.X. (there are three commas): the smallest unit is 1 Khz; the range 1 KHz -150 KHz Frequency display example: "100" indicates that the PWM output pulse is 100Hz "54.1" indicates the PWM output pulse of 54.1 KHz "1.2.4." Indicates that the PWM pulse output is 124 KHz Duty Cycle in the range: 0 to 100 Three frequency duty cycle is the same, all parameters non-volatile. Parameter: Working voltage: 5--30V, support micro USB 5.0 V power supply Frequency range: 1Hz -150 KHz The frequency accuracy: ± 2% Output current: <30mA Output amplitude: Standard 5Vp-p (adjustable) Temperature: -30 -70 ° C
