I build a lot of strange things. These boards come in very handy. They take solder very well and come in standard spacing that lines up with solderless breadboards. Makes it very easy to transfer your temporary breadboard projects to more permanent locations.

Well built. You will need a battery holder too. Bat - goes to A- Bat+ goes to A+ Use heavy short wire. These connections go to the outer heavy cone shaped battery connections on the holder. Also connect the thinner sensor wire shown here in red and black. Pay attention to the polarity of the plug. My wires were reversed so I had to take them out and switch them in the plug. I could have just wired it without caring about the color but not everyone speaks English and will only look at the pictures. Sensor wire red positive goes to V+ on the battery holder. Sensor wire negative black goes to V- on the battery holder. These connections go to the small spring loaded pins in the middle of the battery connections. THE INNER AND OUTER CONNECTIONS OF THE BATTERY CONTACTS MUST ALL BE TOUCHING THE BATTERY TO MEASURE EVERYTHING!!! The power from the micro USB is 5V 500mah. Here is a link to instructions on how to use this tester. https://syonyk.blogspot.com/2016/01/zb206-battery-tester.html

Very nice! This is the second one I have ordered. I mounted this one in a small box to make a portable variable power supply. Since the control board comes off I can store it in the box with all the wires. I soldered everything instead of using the screw connectors but those work good too. Great value. Very happy!

Perfect replacement for my little radio with a broken antenna. Well built and works smooth. Slightly longer but now it has better reception!

Very nice! Quite powerful too. I am running 4 speakers in a small ammo can with this. running two 1.5 inch 4 OHM 3 Watt and two 2 inch 10 watt 8 Ohm speakers with 4 inch PVC pipe added to each speaker to make the sound better. Any old laptop power supply up to 24 volts will run this, mine is 19 volts. If you use the plug make sure the positive is in the middle of the connector. It gets quite hot and I may have to add a cooling fan.

Great quality. gold plating and very nice plastic. Took solder quite well. I made a small bench top variable power supply with mine.

Works very well. Small size but lasts about ten hours on continuous mode which is perfect. Got it as a gift for my mom and she really liked it!

This is without a doubt the best upgrade you can make for your 3D printer to lower the amount of noise it makes! I had to reverse my motor plugs because for some reason it swapped the motor direction when I put them in. And make sure you do not put them in backwards! compared to the old drivers these look backwards but they are not. Check your wiring carefully before putting them in. I only swapped out X and Y but the difference in noise level is amazing! Now I need quieter fans LOL! Well worth the upgrade. My printer is quiet as a mouse now!

Very handy. I made a small bench top power supply with some of mine. The connection on the back goes to the middle inner pin which is normally positive. The other two go to the outer contact which is normally negative.

Pretty good, worth the $ I spent. Not so expensive I have to worry about it. Perfect for throwing in the bottom of the tackle box.

Arrived well packed and was undamaged. I even threw it on a granite plate and tested it for any sort of bow or bend. Perfectly flat!
