Rasp is explicitly mentioned in the OP.<p><i>Why don&#x27;t I just use a Raspberry Pi?</i><p><i>The Raspberry Pi is a fantastic product, but it is built with an emphasis on education and &#x27;home hacking&#x27;. It lacks certain features found in the Ocean. Raspberry Pis do not have built-in Bluetooth or Wifi, and do not come with an on-board power source. While you can purchase cases for them, these cases are rarely designed with portability in mind. Exposed GPIO pins tend to bend in your pocket. A Raspi can be augmented with additional hardware to equal the feature set of the Ocean, but this hardware will compromise the portability of the Pi.</i>
