We start by downloading the eagle files to make the FABNET. The FabNet is a multi-drop network, meaning that multiple modules (a.k.a. nodes) share a single set of communication wires. Signaling is differential based on the RS-485 specification. Each node is assigned a four-byte IP address which uniquely identifies it over the network. To make the board we need the following materials:
(1) Eight pin connector, (1) Four pin connector, 2 resistors (value 600ohm) and (1) six pin connector. We milled and soldered the boards with the files provided.
Once the FabNet was ready we follow by connecting the boards following the images provided in Shawn’s tutorial.
