Digital Servo Tester

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!

Worked as described, makes centering and testing servos a breeze

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.

It's build quality is good, servo accuracy is close to perfect, and the price is great for what you're getting. The Small size is decent. The only thing that I dislike is that it fried a week after the return window closed. I wasn't using much power, only a 5v USB.

I like that it can be powered from the balance plug of a lipo battery or you can connect a power supply or connector to the handy screw terminals for power. The digital readout tells you the power supply voltage. The push-button lets you select either 'middle of travel' mode or control by the knob. There is no 'auto' mode, but it is great for testing a servo or setting up travel when installing one. You can control two servos at a time, they are slaved together. This is a simple device, it works well and was very inexpensive. You should probably cover the bottom of the board to prevent accidental shorts from metal on your workbench. I glued a piece of plastic on mine. For the money, this is a great little device.

Needed an easy way to set up servos and test, this worked just fine, worth the time it saved to make up a temporary solution, and I can test servos easily whenever I need to. I cut the USB 2.0 B end off a cable, wired up +5v and Gnd to this board, and plugged into a 5V 3A USB 2.0 adapter, worked great. I haven't checked the signal timing / accuracy, but it should be good enough. Operation - the buttons set the servo to "center" mode, causing the servo to immediately move to center - if you press a 2nd time, the servo will immediately return to the position dictated by the potentiometer. Only way it could have been better would have been to have a USB cable for power.

Knobs are a bit close together. Can only control one servo at a time. Position at startup needs a delay factor. (When you initiate a particular servo, it sends a full speed signal that "slams" the servo to the correct position.) I think they call this board a "servo tester". As a servo tester, ok, it does great. All my servos were tested. But it's got very limited capability beyond just a tester.

Excelente

scheda arrivata in anticipo rispetto al periodo ipotizzato. seconda scheda acquistata.

Debería ser un poco más grande Los potenciómetro están muy juntos

一番コンパクトにサーボモータを動かしたくて購入しました。5VのAC電源アダプタを購入してサーボモータに繋げると簡単に動かす事が出来ました。

Just what I was looking for to test my servos, no issues and smooth responses on each servo

６チャンネルもあって単純さゆえにいろいろ応用できそう。
