A PicoBoard was a piece of hardware that allowed Scratch projects to interact with the outside world. Currently, it works on Scratch 1.4 and Scratch 2.0. It was removed in Scratch 3.0, with the new extensions being favored more.
|Caution:||Before buying a PicoBoard, note that it will not work with Scratch 3.0.|
The PicoBoard can be ordered from SparkFun. The schematics and additional information are also available on that site.
The previous version was called the ScratchBoard. It has the same components and is compatible.
The Connecting to the Physical World forum is a place dedicated to discussions about the PicoBoard and other real-world Scratch sensors.
