Product Description
Description:
Three-channel PWM is outputted,wide frequency range and the duty ratio can be adjusted independently
Frequency is divided into four areas,automatic switching:
1.XXX(No decimal point): 1HZ Stepping Unit,Range:1Hz~999Hz;
2.X.XX(The decimal is in the hundreds place):0.01KHZ Stepping Unit,Range: 1.00Khz~9.99Khz;
3.X.XX(The decimal is in the tens place):0.1KHZ Stepping Unit,Range: 10.0Khz~99.9Khz;
4.X.X.X(The decimal is in the ones place):1KHZ Stepping Unit,Range: 1Khz~150Khz;
e.g. ,frequency display:100 represent the pulse of 100Hz ;
1.01 represent the pulse of 1.01KHz;
54.1 represent the pulse of 54.1KHz
1.2.4 represent the pulse of 124Hz
The value range of dutyfactor: 0~100%,100% is represented by A0%.
All parameters setted up can be automatically saved in case of power cut.
Parameter:
Has 8 independent keys,used to set the frequency and duty ratio,support short press (increase or decrease a unit) and long press (fast increase or decrease),very simple,set the parameters automatically save,power loss.
3-Way duty ratio button can be pressed at the same time,real-time adjustment, liquid crystal display is the last pressed button duty ratio,real-time is very strong,can be used as a simple several road duty ratio scan.

Package includes:
1 x 3 Channel PWM Pulse Generator Module
1 x 13pin header
1 x 20pin male and female Dupont cable
