Before the Raspberry Pi came out, one cheap and easy way to get GPIO on a computer with a real operating system was to manipulate the pins on an old parallel port, then most commonly used for print…

    This…seems completely insane. Like buying a pickup truck to drive a motorcycle around because you don’t want to bother getting your M-class license.

    That PSU is insane for a board that can run off 5V.

    This would appear to indicate that someone in charge of product design at Pi HQ is a Gen X-er or Boomer desperate to relive computing history through their own products.

    Computer on a board. Bigger computer on a board. Computer entirely within a keyboard.

    And now a computer in a PC-like case.

    Prediction: The next step will be some kind of ARM-based cloud service.

      This doesn’t appear to be made by the people from either the Raspberry Pi Foundation or Raspberry Pi Holdings.

    I thought one of the selling points of Raspberry Pi was its small form factor…?

      I guess you might want to link the psu to a bunch of relays that controlled by the gpio, and use it to deliver medium amounts of power to various peripherals. i guess lots of motors or maybe fairly powerful led lighting arrays, or weak heaters , comes to mind.

      So what seemed most daft to me is exposing the 3v and 5v lines on that breadboard like thing, but not using the psu’s +/-12v lines - that could let you run 12 and 24V stuff. plenty of space to allow for a bunch of relays and some connectors.

      But even so its a strange form factor for that.

    You’re better off with a Beaglebone if you want GPIO. The Raspberry Pi doesn’t have any analog pins, for one thing.
