Means of connection

There are a number of types of Raspberry Pi. The preferred options are the A and B variants. To use the A

variant you will require a ribbon cable to connect to the Module Development Board. Figure 6 below shows a

Raspberry Pi Model A with the ribbon cable connected.

As an alternative to the ribbon cable it is possible to get 2*13 header connectors with extra long pins. Such a

connector is shown in Figure 7. One supplier of these connectors is https://www.modmypi.com. Search for part

number MMP-0275.
