The Robotic Hot is an input and motor board for Pixie 14 via 2 Pixie Ports in an 'Arduino' shield format. The board provides 2 bidirectional motor outputs via an L293D driver and 5 inputs with pull-down resistors for ease of connection of switches etc, 2 inputs are also available as analogue ports. The board takes a 5V 1A voltage regulator to supply both the Robotic Hot and Pixie 14, the on-board motor driver can select to use either 5V or +V voltages for the motors if needed via a simple link.
