Automation peripherals for Arduino (real-time processor board extension)

Currently, we are building up a suite of Arduino-driven peripherals for research and education. The peripherals are designed for use with industrial automation components, but give more design freedom and are easier to observe than off-the-shelf PLCs and automation equipment. This is already the second batch of PCBs for the equipment, and we are really impressed with the consistently excellent quality of PCBWay's boards, fast and predictable manufacturing and shipping, as well as with their quick and helpful communication.
