Description:
2-Channel PWM Signal Generator PWM Pulse Frequency and Duty Cycle Adjustable 2-channel Signal Generator Module for Square and Rectangular Wave is a 2-channel PWM/Pulse generator with variable Frequency: 1hz to 150 kHz and Duty cycle 1% to 100% alterations. The frequency and duty cycle can be controlled using switches provided on board. It can also be controlled using a serial communication protocol. This module provides an easy solution for driving stepper motors using variable frequency pulse input and DC motors with variable PWM duty cycles.

Setting PWM Frequency:
- "S1FXXXT": set PWM1 frequency as XXX HZ (001~999)
- "S1FXX.XT": set PWM1 frequency as XX.X KHZ (00.1~99.9)
- "S1F: X.X.X.T": set PWM1 frequency as XXX KHZ (0.0.1.~1.5.0.)
- "S1": PWM1
- "S2": PWM2
- "F": frequency
- "D": duty cycle
- "T": stop sign bit
Setting PWM Duty Cycle:
- “S1DXXXT”:set PWM1 duty cycle as XXX；(001~100)
- “S2DXXXT”:set PWM2 duty cycle as XXX；(001~100)
Parameter Setting:
- The module has a 3-channel key: Set, Up, Down
- By short pressing the SET key, can shift displays 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
- Directly press the UP, and DOWN keys to modify the current parameter value
- 2-channel PWM is set 3 kinds of frequency values, in the frequency display interface, by long press SET to shift,3 kinds of frequency’s duty cycle is the same （XXX:1Hz~999Hz; XX.X:0.1Khz~99.9Khz; X.X.X.:1Khz~150Khz).
Package Included:
1 x 2-Channel PWM Signal Generator
