Pi Plate
The Pi Plate, shown in Figure 9-7, is another product from Adafruit
(https://www.adafruit.com/products/801) . This is a prototyping board that has a large area in the
middle to which you can solder the components for your project. Screw terminals are located all
around the edge of the board so you can attach leads to external components that won’t fit on the
board, such as motors and such. In one corner of the board is an area to which a surface mount IC can
be soldered. The pins next to it “break out” the difficult-to-use pins of the IC.

Humble Pi
The Humble Pi, shown in Figure 9-8, is quite similar to the Pi Plate, but it lacks the surface mount
prototyping area. However, it makes up for this by providing an area where you can add your own
voltage regulator and power socket, making it suitable for powering the Pi at 5V from batteries or an
external power supply. No voltage regulator or associated capacitors are provided, although Ciseco
sells a kit of components for this.
