## Description

desertcart.com: RC Digital Servo Tester 6 Channels Motor Servo Controller Centering Tool with Over-Current Protection & 2 Control Modes for RC Car Airplane Robots Tester Tool : Toys & Games

Review: Must have tool for testing servos - Worked as described, makes centering and testing servos a breeze
Review: Great little tester - Got this tester for use by my robotics students. It is a great little unit that is easy to use. The button provides access to two modes: Neutral (centers the servo) and Manual, which allows the user to turn the servo based on the position of the potentiometer dial. Small LEDs, located just left of the digital voltage display, show which mode is selected. There are two ways to power the board: one accepts the standard JST-XH charging balance connector, and the other accepts a direct wire connection. Would have been nice to have a female T-plug connector, but you can't have everything. Well worth the price.

## Features

- Specifications: 76mm*53mm(2.99in*2.09in); Weight: 37g (1.31oz)
- Power Supply: This controller can be powered by either a Lipo battery or a power adapter, operating within a voltage range of 5-8.4V.
- Manual Adjustment: The controller has 6-channel PWM digital servo port, adopts high-accuracy potentiometer for precise servo control and provides servo reset function.
- Support PWM Servo: It supports a wide variety of PWM servos, allowing manual angle adjustments without the need for coding.
- Controller Accuracy: Its control accuracy can reach up to 0.09° (with a 1us PWM limit for minimal changes)
- Overcurrent protection: The controller offers 3-channel overcurrent protection to prevent damage to the servo.
- Versatile Applications: It can be applied in gripper, AI robot, robot arm and more.

## Questions & Answers

**Q: What is the min and max pulse width output?  I have servos that require .7ms to 2.3ms.**
A: 0.5~2.5ms

**Q: Could this device be used with futaba nr4j nicd 4c 4.8v 600mah flat receiver j**
A: This is a servo test device. The output from the device simulates the output from the receiver to test the servos

**Q: Does this output PWM**
A: Yes, although it doesn't display the values. It works well for my multi-channel testing and prototyping projects.

**Q: Does this work with Arduino?**
A: If you use Arduino to control servo motors, you many not need this product.

### ⭐⭐⭐⭐⭐ Good Function
*by S***O on May 30, 2020*

Nice the hands are able to move now! 😂 I'm so glad I got this as it is straight forward no need to complicate things right away. I'm no expert at these things yet sorry in advance for my tiny brain but it is mostly plug and play with your servos. Although you do need to use a separate power source and be sure the volts do not exceed 4.7v being the limit on most servos I believe. I kinda ran a 9v battery with it still with no problems but I tend to do these things often. Good for experimenting but I dont think it can constantly rotate so it's mostly 180° back and forth motions with the dials. This is great if you're doing something like me trying to figure out the next Bionic hand and such. May not be what u need for a RC Drone or Car tho, but again I'm no expert. Works with the hands sold by the same company very well. Edit: HOLD ON! Here is what I used on the picture actually before I forget. Sorry, I tend to work on these things on my spare time and that's not a lot... So, 9v will likely not be good directly.. unless u can regulate it or something. With this green light thingy I have it hooked up to 5V which is really good too I guess. The other pic also that blue with red display thingy as you guys probably know is a buck converter. This can help if u do use a 9v. As I said the volts need to be specific if not it will not be able to function at all. Great hand either way!
