PWM Stepper Motor Driver Simple Controller Speed Controller Forward and Reverse Control Pulse Generation

Image
Get PWM Stepper Motor Driver Simple Controller Speed Controller Forward and Reverse Control Pulse Generation Feature:    Product name: simple controller Model: CW-S01 It can generate PWM signal. There is a jumper on the board, which can be set and selected. By default, it is set to generate pulse frequency signal.   Product Manual: 1. When the controller generates a pulse frequency signal, it can supply a stepper driver as a signal. To control the stepper motor, it must be equipped with a driver. (This simple controller + stepper driver + stepper motor + DC power supply can form a simple control platform.) 2. The controller can generate a pulse frequency signal or a PWM pulse width signal. There is a jumper on the board, which can be set and selected. By default, they are set to generate pulse frequency signals. REQ is to generate pulse frequency signal PWM is to generate PWM signal 3. When the controller generates a pulse frequency signal, there are three types of high, medium and low...

Buy 10pcs 4 Digit 7-Segment 0.56' LED Display Tube Decimal 7 Segments HT16K33 I2C Clock Double Dots Module For Arduino >>>Manual: Click here to open<<< Features:   - These 7-segment displays normally require 13 pins (5 characters and 8 total segments each). - Solves the annoyance of using 13 pins or a bunch of chips by having an I2C constant-current matrix controller sit neatly on the back of the PCB. - The controller chip takes care of everything, drawing all the LEDs in the background. - All you have to do is write data to it using the 2-pin I2C interface. - There are three address select pins so you can select one of 8 addresses to control up to 8 of these on a single 2-pin I2C bus (as well as whatever other I2C chips or sensors you like). - The driver chip can din the entire display from 1/16 brightness up to full brightness in 1/16th steps. - It can't din individual LEDs, only the entire display at once. - Size: 5.03 x 2.68 x 1.2 cm/2 x 1.1 x 0.5 inch  ...
