This is the demonstration gadget I built to show the Raspberry Pi basic operation. It is programmed to activate 8 GPIO ports to drive 8 Relays, 3 GPIO ports for PWM and motor control and 2 GPIO ports for solenoid. Infrared sensors and ultrasonic sensor are also incorporated for robotic and automation controls. This kit can help those beginners, hobbyists, technicians or engineers to learn and test the Raspberry Pi safely using a rechargeable battery. This will be available soon as kit or assembled and by order basis. See the Kits & Gadgets on Sale page for an update.
