Gertboard Review – Bridging Raspberry Pi and the outside world

The Raspberry Pi is limited with its access to the outside world, e.g. out of the ‘virtual’ softare realm.  Lucky we got Gertboard that introduces us to the physical computing concept.

What can it do?

  • Run motors out of its motor port
  • Run Arduino shields, through its ATMega 328
  • Run both digitial and analog devices
  • Run servos from its buffer outputs
  • Run more servos from its relays
  • Light up some leds
  • Even roll your garage door through its relays

Although its very complete, the number of ports available for motors is very limited to 1 port. This is not ideal for a driving rovers. A few tips for connecting to Raspberry Pi via GPIO rainbow cable. You basically needs two cables connected to each other , because it is an iverted cable, so you got to invert it back for it to work properly.

You can run Arduino sketches on Gertboard via its ATMega board. Refer to https://www.linuxcircle.com/?p=499 for wiring setup and installation.
