The Motorino board is an extension-board to control and use up to 16 PWM-controlled 5V-Servo-motors. The included clock generator ensures a very precise PWM signal and a very precise positioning. The board has 2 inputs for voltage from 4.8 V to 6 V which can be used for up to 11 A. With this input, a perfect power supply is always guaranteed and even bigger projects are no problem. The supply runs directly over the Motorino which provides a connection for voltage, ground and control. With the build in capacitor, the voltage is buffered which prevents a sudden voltage-drop at a high load. But there is also the possibility to connect another capacitor. The control and the programing can be done, as usual, with the Arduino. Manuals and code examples allows a quick introduction for beginners. Special features 16 Channels, own clock generator Input 1 Coaxial power connector 5.5 / 2.1 mm, 4.8-6 V / 5 A max Input 2 Screw-terminal, 4.8-6 V / 6 A max Communication 16 x PWM Compatible with Arduino Uno, Mega and may more microcontroller with Arduino compatible pinout Dimensions 69 x 24 x 56 mm Scope of supply Board, Manual, Retail package
