Wide Range Power Supply for Raspberry Pi
With the PiEnergy Mini, you can operate your Raspberry Pi with a voltage of 6 to 36 V DC. You can use the button integrated on the board to both power up and power down your Raspberry Pi.
Communication with the Raspberry Pi is via GPIO4, but this connection can also be cut by removing a resistor to use the pin freely. Thanks to the ultra-flat design, it can also be used in many housings. The pin header is included and not soldered on to keep the design even flatter.

The JOY-iT R301T fingerprint sensor module is capable of image collection and algorithm calculation due to this integrated chip. Another remarkable function of the sensor is, that it can recognize the fingerprint in different conditions, for example humidity, light texture or changes of the skin. This offers a very wide range of possible applications to secure locks and doors among others. The chip can send data via UART, TTL serial and USB to the connected controller.

This JOY-iT microcontroller board opens the world of programming to you and offers you the same computing power as the Mega 2560, but with a smaller foot-print. It also has many more connectors than comparable boards (Arduino Uno). It is powered by the Arduino IDE and power can be supplied either via the USB port or the VIN pins. This allows you to use it safely with many other devices, e.g. desktop PC. Therefore the Mega 2560 Pro is highly integrable.

Manual
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.

The MotoPi is an extension-board to control and use up to 16 PWM-controlled 5 V servo motors. The board can be additional powered by a voltage between 4.8 V and 6 V so a perfect supply is always guaranteed and even larger projects can be powered.
With the additional power supply and the integrated Analog-Digital-Converter, new possibilities can be reached. An additional power supply per motor is not required anymore because all connections (Voltage, Ground, Control) are directly connected to the board.
The control and the programing can be directly done, as usual, on the Raspberry Pi.
