The world of robotics is fascinating and stimulating, Poldino is a low-cost educational platform designed to bring everyone close to this interesting field.
This is a board of about 10x5 cm in size that integrates two 1Ampere H bridges, to drive two DC motors. This board can be used individually or you can make the PoldinoBot that includes a 3D print frame, two DC motors, wheels, a ball caster and two proximity sensors.
Poldino is based on microchip 18F4550 processors, so it can be programmed with the appropriate IDE with its interface ICSP, or more simply through the micro USB port on board. The second option is possible with the IDE Pinguino (Creative Common license www.pinguino.cc) which allows you to program the card using the C language.
The board can be powered by a single source, or by separating the power from the logic to that of the motors. The minimum supply voltage is 6V the maximum (for bridges) of 11V.
The in / out pins are arranged so that you can also plug 3 jumper with 5V power supplies to be deployed to facilitate the use of powered sensors. On board there is also an I2C bus, which can be enabled by means of special jumpers.
