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. Specifications Input voltage 6 to 36 V DC Output voltage 5.1 V Output current Up to 3 A (active ventilation recommended for additionally connected loads) Cable cross-section at the power input 0.2-0.75 mm² Interface to the Raspberry Pi GPIO4 Microcontroller ATtiny5 Further connections 5 V fan connector (2-pin/2.54 mm)Solder pads for external on/off switch Compatible with Raspberry Pi 3, 4, 5 Dimensions 23 x 56 x 11 mm Included Board with mounted heat sink Pin header (2x5) Spacer, screw, nut Downloads Datasheet Manual

Het Motorino bord is een uitbreidingsbord om tot 16 PWM-gestuurde 5V-Servo-motoren aan te sturen en te gebruiken. De bijgeleverde klokgenerator zorgt voor een zeer nauwkeurig PWM-signaal en een zeer nauwkeurige positionering. Het bord heeft 2 ingangen voor een spanning van 4,8 V tot 6 V die gebruikt kan worden voor maximaal 11 A. Met deze ingang is een perfecte stroomvoorziening altijd gegarandeerd en zijn zelfs grotere projecten geen probleem. De voeding loopt direct over de Motorino die zorgt voor een aansluiting voor spanning, massa en aansturing. Met de ingebouwde condensator wordt de spanning gebufferd wat een plotselinge spanningsval bij een hoge belasting voorkomt. Maar er is ook de mogelijkheid om een andere condensator aan te sluiten. De besturing en het programmeren kan, zoals gebruikelijk, met de Arduino. Handleidingen en code voorbeelden maken een snelle introductie voor beginners mogelijk. Speciale kenmerken 16 Kanalen, eigen klok generator Input 1 Coaxiale voedingsconnector 5,5 / 2,1 mm, 4,8-6 V / 5 A max Input 2 Schroef-terminal, 4,8-6 V / 6 A max Communicatie 16 x PWM Compatibel met Arduino Uno, Mega en wellicht meer microcontroller met Arduino-compatibele pinout Afmetingen 69 x 24 x 56 mm Werkingssfeer Bord, Handleiding, Winkelverpakking

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. Special features 16 Channels, own clock generator, Inkl. Analog Digital Converter Input 1 Coaxial power connector 5.5 / 2.1 mm, 5 V / 6 A max Input 2 Screw terminal, 4.8-6 V / 6 A max Compatible with Raspberry Pi A+, B+, 2B, 3B Dimensions 65 x 56 x 24 mm Scope of supply Board, manual, fixing material
