LM7812 IC-12V Positive Voltage Regulator IC
LM7812? of three terminal positive voltage regulator in the TO-220 package and with fixed positive 12 volt output. Making LM7812 useful in a wide range of applications. It employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1 Ampere output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

Digital Multi Servo Tester ESC RC Consistency CCPM Master Speed Control
- The Digital Multi Servo Tester ESC RC Consistency CCPM Master Speed Control offers 3 modes to check servos or ESC. The Manual Mode allows you to turn the knob to different speeds and check the reaction time. The Neutral mode makes the servo go back to the neutral point. The Automatic Window Wiper Mode makes the servo swing like a window wiper in the largest angle possible.
- Plus, this servo tester can connect to up to 3 servos simultaneously. You can also connect up to 3 ESCs to test and compare their reaction time respectively
- DNA Solutions has large collection of various types of Motor Driver Module. Check our complete collection of Motor Driver Modules.
