• LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle;
• Wide frequency range, high precision;Duty cycle range: 0 100 ;
• Serial communication, TTL level
• The module has four independent keys, used to set the frequency and duty cycle, support touch and long press , set the parameters automatically save, power down Not lost.

Frequency is divided into four ranges, automatic switching: 1. XXX : the smallest unit is 1Hz, the value range of 1Hz 999Hz; 2. X.XX the smallest unit is 0.01Khz, the range of 1.00Khz 9.99Khz; 3. XX.X : the smallest unit is 0.1Khz; value range of 10.0KHz 99.9KHz 4. X.X.X : the smallest unit is 1Khz; value range 1KHz 150KHz frequency display: 100 indicates PWM output 100Hz pulse; 1.01 indicates PWM output 1.01K pulse; 54.1 indicates that the PWM output has a pulse of 54.1 kHz; 1.2.4 indicates that the PWM output is 124 kHz pulse; The module parameters: Working voltage: 3.3 30V; Frequency range: 1Hz 150KHz; Frequency accuracy: the accuracy in each range is about 2 ; Signal load capacity: the output current can be about 5 30ma; Output amplitude: PWM amplitude equal to the supply voltage; Ambient temperature: -20 +70 .
