===== Design Choices ===== | ===== Design Choices ===== | ||
+ | |||
+ | ==== Processor ==== | ||
+ | |||
+ | Using the KISS design principle, we decided early on to use a Computer on a Module for our main processor. | ||
+ | |||
+ | ==== Input / Output Methods ==== | ||
+ | |||
+ | It was known right from the start that an LCD module would be used to display any sensor data. But, what was not known was what input methods would be used for a user to interact with the User Interface of the Tricorder. | ||
+ | |||
+ | ==== Casing ==== | ||
+ | |||
+ | In choosing the material for our case, we wanted something durable, light weight, not expensive, be easy to obtain and be malleable enough so that it could be designed by a variety of methods. | ||
==== Ports ==== | ==== Ports ==== | ||

The Tricorder had to be portable, so it needed a portable power source, a battery. |

+ | ==== Printable Circuit Board ==== | ||
+ | |||
+ | We wanted to design and build from start to finish, a Printable Circuit Board (PCB) that would have all the sensor so that they could connect to the main board. | ||
