Interesting question, @onky. Actually a couple years back PICMG started developing a firmware specification around IoT data models that is designed to abstract sensor-vendor-specific data formats so there can be data transparency between sensors and controllers and controllers and the rest of the infrastructure.

In parallel they developed a small form factor, open-source, microcontroller-agnostic platform called MicroSAM. Here are some of the high-level features:

  • Full industrial operating temperature range from -40C to +85C.
  • Power filtering and signal conditioning for embedded installations
  • RS422 communications link for reliable communications
  • Direct connectivity to a variety of sensor types (analog voltage, analog current, digital)
  • Latching connectors for secure connectivity
  • PWM output for motion control applications
  • Hardware interlock and trigger signals for synchronization
  • Small size (32mmx32mm)
  • Low power consumption

Depending what you are working on, how far you've gotten, and how well this aligns with your goals, I'd recommend reaching out to @DougSandy. He's the CTO at PICMG and lead both the IoT firmware and MicroSAM specification development efforts. I know he's always interested in collaboration.
