• 5 Volt, 2 Amp high efficiency switching power supply – to power the RPi from a battery pack, 6V – 14V input voltage range.
  • Laptop style power button. One button for on, off and reset. Complete disconnection of the battery when switched off – zero power drain.
  • Proper shutdown procedure, power is only removed after the Pi has acknowledged the shutdown command. Battery level monitor with low battery safe shutdown.
  • Start up battery check, the Pi will not be switched on if the batteries are too low. Battery level indicator – Green for good, orange for medium, red for low, slow flashing red for very low,  fast flashing red for shutting down.
  • The Arduino runs the power control system – there is plenty of space available for custom code. 
  • I2C and SPI communication between the Arduino and RPi, with headers available for custom use.
  • Fully programmable from the RPi – no USB connection required, the Arduino development environment can be run within the RPi desktop. 
  • Battery screw terminals 
  • 2 x Motor dual screw terminals 2 x Servo motor connectors – For controlling two hobby servos, uses 2 RPi GPIO pins
  • Connector for the Red Robotics LaserTanks IR Board.
  • I2C Header
  • SPI Header
  • Direct connection of NRF24L01 Wireless Transceiver
  • All unused Arduino pins available on headers
