One challenge with piecing together devices are the connections.  We discussed how we’ll use communications protocols to link devices that are physically separate.  This same problem occurs for our nodes that have sensors, controllers, or other circuit boards that need to be linked.  To solve this, we’ll develop and manufacture printed circuit boards, or PCBs as they are commonly referred to.  Having a custom PCB that makes the links also provides us a cleaner build.  In addition, devices can be … Continue reading PCB Design
