The Productivity®Open platform provides all the great features of a standard Arduino plus the added power and reliability of an industrial controller. The P1AM-100 Arduino-compatible CPU is compatible with most available Arduino MKR format shields, and/or the industrially-hardened ProductivityOpen shields, and can utilize most Arduino sketch programs found on open-source websites. The P1AM-100 CPU supports the full line of Productivity1000 I/O modules including discrete, analog, temperature, relay, high-speed input and pulse-width-modulation modules. The industrial-grade P1AM-100 Arduino-compatible CPU is $49.00. Priced from $32.00, available ProductivityOpen UL-certified shields include the P1AM-ETH Ethernet shield and the P1AM-GPIO general purpose I/O shield. The P1AM-PROTO shield is also available for creating your own prototype designs.
