Apie prekę

This generator has 4 ranges set by a jumper link with these approximate values:

1Hz to 50Hz
50Hz to 1kHz
1kHz to 10kHz
10kHz to 200kHz

Assuming you have a 200 step stepper motor with a controller set to 1/4 micro stepping, then with this pulse generator you could have a stepper rotate as slow as one rev per 13 minutes at 1Hz. The maximum (subject to the motor being capable of it) would be at 200kHz 15,000 rpm.

A multiturn pot on the PCB set the frequency between the minimum and maximum values for the selected range. The other pot is used to set the duty ratio (mark space ratio) which is basically how long the pulse is on for against how long it is off for. The duty ratio is not that important for stepper circuits so best to have it in the mid position. An on-board LED can be used to set the duty ratio with a low frequency to set the on / off durations to be about equal.

Supply volatge is 5-15V but when used for a stepper motor controller, the supply voltage should match the logic voltage of the controller, typically 5V. Current consumption is about 15mA at 5V rising to 35mA at 12V
