Over the past couple months, I took it upon myself to learn PCB design as an addition to my skill set. The Cantaloupe is the result of this effort. It allows up to 20 devices to be connected in a star configuration, and also has optional termination of the loop built in.
wow cool can we buy it?
We’re not selling it at the moment, but the github repo contains all the files necessary for you to make one of your own!
