There are only five ground pins available on the header, but some gamers will need more controls than that. One of our {{pl|223|medium Perma-Proto boards}} can be used to provide a single large “ground rail” where one side of all the buttons can be connected. Alternately, if you have extra unused GPIO pins and just need a couple extra ground connections, we’ll show a software work-around for this. | There are only five ground pins available on the header, but some gamers will need more controls than that.
