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!

Great hand either way! ### ⭐⭐⭐⭐⭐ Must have tool for testing servos *by A***R on November 29, 2025* Worked as described, makes centering and testing servos a breeze ### ⭐⭐⭐⭐⭐ Great little tester *by L***T on February 2, 2025* 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. ## Frequently Bought Together - 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 - Miuzei MG90S 9G Micro Servo Motor Metal Geared Motor Kit for RC Car Robot Helicopter, Mini Servos for Arduino Project (10) - HiLetgo 2pcs PCA9685 16 Channel 12-Bit PWM Servo Motor Driver IIC Module for Arduino Robot --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/47304934-rc-digital-servo-tester-6-channels-motor-servo-controller-centering](https://www.desertcart.in/products/47304934-rc-digital-servo-tester-6-channels-motor-servo-controller-centering) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-04-23*
