More shipping info

The PWM generator module has two independent PWM outputs that set the frequency and duty cycle, The adjustable signal generator has a wide frequency range and high precision. The adjustable square wave signal generator can communicate serially. A rectangular wave signal generator can be used to generate adjustable pulses and control related circuits. The rectangular signal generator uses a microcontroller to generate a pulse to produce an adjustable circuit associated with pulse control
Module has 3-channel key:Set,Up,Down
By short press SET key, can shift display 4 parameter values (FR1:PWM1 frequency; dU1:PWM1 duty cycle; FR2:PWM2 frequency; dU2:PWM2 duty cycle); before shifting,there will be corresponding parameter name flashing
