Building an isolated RS-422/RS-485 shield for the ProductivityOpen controller
Glen Akins, Engineer and part time gadget builder, is back with another add-on for the P1AM-100 ProductivityOpen open-source controller. This time, Glen built an isolated RS-422/ RS-485 shield, loosely based on the Arduino MKR RS-485 shield but updated to use an ADM2582E 3.3 V isolated RS-485 transceiver from analog devices. This add-on gives RS-422 and R485 communication capabilities to the ProductivityOpen and can be housed inside the P1AM-PROTO prototyping enclosure.
