 A PLC with ethernet, USB host, USB device, 2x CAN interfaces and 2x RS485 interfaces built around the SAMA5D27-SOM1 module from Microchip. It runs a buildroot-based Linux in my basement with a bunch of python scripts to control my HVAC. Personal project. Base for a controller board for another commercial project. A PLC with ethernet, USB host, USB device, 2x CAN interfaces and 2x RS485 interfaces built around the SAMA5D27-SOM1 module from Microchip.
