Description
An industrial PLC with a Raspberry Pi RP2040 core
Iono RP features a wide set of digital and analog input and output lines, power relays and industry-standard interfaces, all routed to the powerful dual-core Arm Cortex-M0+ processor of the Raspberry Pi RP2040 microcontroller.
Developing on Iono RP is easier than ever: write your code in C/C++ or MicroPython, use your preferred IDE among the many available options for the RP2040, no need for proprietary libraries or drivers and all the available resources from the Raspberry Pi community will transparently work.
Iono RP can be employed both in industrial and residential environments, for professional applications where extreme reliability, ruggedness and compliance with technical and safety directives are required.
It is compliant with the low voltage and EMC CE directives, as well as the harmonised standards for electromagnetic compatibility, electrical safety, emission and the RoHS directive for hazardous substances. It is also compliant with the applicable FCC rules and IC standards.
