Tiny, Open-source PLC for Industrial IoT

Here’s an ultra-compact PLC reference design that provides multiple software-defined I/Os in an ultra-compact (less than 1 cubic inch) solution, designed to increase productivity and reduce downtime in industrial and building automation applications.
The Go-IO reference design (MAXREFDES212) is a next-generation industrial IO solution that is designed to increase productivity, further adaptive manufacturing, and provide machine-level health and status information for making critical, real-time decisions.

To address the current trends of Industry 4.0, the design claims to meet stringent size and power demands. Go-IO packs 17 configurable IOs in a space one-half the size of a credit card. It is also touted to be a 10x smaller solution with 50% less power consumption compared to its predecessor, the Pocket IO.
Key advantages

Compact Design
Ultra-small, compact footprint (< 1 cubic inch: 1.7in.W x 1.56in.D x 0.25in.H) allows Go-IO to be integrated throughout the factory floor
Robust, Safe Technology
Composed of advanced industrial products rated to withstand -40°C to +125°C
High Efficiency- Ensures a small energy signature to increase efficiency—no cooling fan is needed
Packs a Powerful Punch
Offers a full suite of 17 IOs to control an entire manufacturing node or piece of equipment, including analog inputs, analog outputs, isolated digital inputs, digital outputs, IO-Link masters, and isolated RS-485 with integrated power
Programmable via the MAX32630 using the low-power Arm®Micro toolchain
Intelligence and Decentralized Control
Enables automation equipment to act autonomously based on changing environments—as issues are identified, equipment can reprogram itself to do another task
Productivity and Throughput Increases
Enables higher factory uptime by supporting the ability to quickly isolate problems
