Description:

Using L298N as the control chip,the module has such characteristics as strong driving ability,low calorific value and strong anti-interference ability. This module can use built-in 78M05 for electric work via a driving power supply part. But to avoid the damage of the voltage stabilizing chip, please use an external 5V logic supply when using more than 12V driving voltage. Using large capacity filter capacitor, this module can follow current to protect diodes,and improve the reliability.

6~28V 3A Motor Speed Controller [B056]

https://www.youtube.com/watch?v=hdwnlHRdqRk

* Specs

This DC Motor Speed Controller allows controlling the direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 0%-100%. 

The motor speed controller can easily provide a continuous current of3A to your DC motor or other DC load. 

Main technical parameters: 

Input supply voltage:6V-28VDC 

The maximum output power: 80W 

The maximum continuous output current :3A 

Duty Cycle adjustable:0%-100% 

Operating instruction: 

1. Connect your DC motor (or DC load) to the motor terminals as indicated on the wiring diagram. 

2. Connect a voltage of 10V-36V DC to the circuit making sure of the correct polarity of the connection. Note that the voltage applied to the motor will be supply voltage applied to the circuit. It is recommended to add an appropriately rated fuse inline with the positive supply in order to protect the circuit from any possible short circuits. 

3. You can now control the speed of the motor through potentiometer.

Features:

CCPM Servo Consistency Master / Servo tester

The device also can be used as a signal generator for electric speed controller (ESC), then you can test your motor system without using a transmitter and receiver.

There are 3 modes to check servos or ESC:

Manual mode: turn the knob with different speed, check the reaction time.

Neutral mode: make the servo go back to the neutral point.

Automatic \"window wiper\" mode: make the servo swing like a window wipers in the biggest angle.

It can connect 1-3 servos simultaneously and test such as 1-3 servos consistency and so on.

You can also connect 1-3 ESC to test and compare their reaction time respectively.

It can connect 3 servos of the CCPM helicopters and select servos.

It can also connect the servo of airplanes install the steering-box and adjust planes by using such as the neutral mode and so on.
