Raspberry Pi CM3+ based Iono Pi Max industrial controller comes with an impressive number of I/Os

As the Raspberry Pi Compute Module 4 is only expected for next year, companies are still launching products based on Raspberry Pi Compute Module 3+ (CM3+), and Sfera Labs has just introduced Iono Pi Max industrial computer powered by a Raspberry Pi CM3+ system-on-module.

Housed in a DIN rail enclosure, the Linux controller offers Fast Ethernet, three USB ports, isolated CAN and serial boards, some analog I/Os, a relay, as well as a real-time clock (RTC), integrated UPS, and more.

Iono Pi Max Industrial Controller

Iono Pi Max specifications:

  • SoM compatibility
  • MCU – Microchip SAME54 Cortex-M4F microcontroller with 1 MB flash, 256 KB RAM connected to the Raspberry Pi module via I2C, USB and CAN. It can also take control of all serial ports, analog, and digital I/O.
  • Storage – Dual MicroSD card sockets (internal) for separate OS/data storage, SD redundancy, and/or in-field full-system upgrades
  • Networking – 10/100M Ethernet port (RJ45)
  • USB
    • 2x  USB 2.0 Type-A ports with individual power control and fault detection
    • 1x internal USB 2.0 Type-A port to embed USB dongles inside the enclosure
  • Serial via terminal blocks
    • Standard RS-232 interface to the Raspberry Pi serial line up to 115,200 bps
    • Standard RS-485 interface routed to the Raspberry Pi serial line or USB with optoisolator and electrostatic discharge protection up to 115,200 bps
    • Controller Area Network (CAN) V2.0B and CAN-FD interface up to 8 Mb/s with optoisolator and electrostatic discharge protection
  • Other I/Os accessible via terminal blocks
    • 5V-level, protected, I2C expansion bus
    • 4x power relay outputs rated for 6A at 250V, with NO and NC contacts
    • 4x open-collector outputs
    • 2x 0-10V or 0-20mA analog outputs
    • 4x analog voltage inputs 0-20V
    • 4x analog current inputs 0-20mA
    • 2x Pt100/Pt1000 temperature sensor inputs
    • 4x digital input lines
    • 4x digital 5V-level I/O lines with 1-Wire and Wiegand support
  • Debugging – SWD interface
  • HW Security – Microchip ATECC608A secure element chip
  • Misc
    • RTC with replaceable CR1220 back-up battery
    • Hardware watchdog controlled by Microchip MCU
    • Front-panel RGB LEDs, user button
    • Piezoelectric buzzer
    • Internal temperature sensor
    • MCU controlled fan
  • Power Supply
    • 10 to 50V DC with surge and reverse polarity protection, and 3.3A resettable fuse
    • Integrated uninterruptible power supply (UPS), with external lead-acid 12V or 24V battery (with reverse polarity and over-current protection)
    • Software-controlled auxiliary 12-24V DC stabilized supply output to power external devices through Iono Pi Max UPS
    • Software-controlled auxiliary 5V DC stabilized supply output
    • Voltage and current monitoring of power supply input, battery and auxiliary supply output
    • Optional earthquake sensor module
  • Dimensions – 6 modules DIN rail case

Iono Pi Max Connection Diagram

The company does not provide any specific OS for Iono Pi Max since it’s based on Raspberry Pi, and any operating system, tools, or framework working on the CM3(+) module will also work on Iono Pi Max industrial controller. Sfera Labs does have a Github account with a kernel driver to control most I/Os, as well as a separate CAN bus driver for the controller. You’ll find plenty of documentation by scrolling down to the bottom of the product page.

Iono Pi Max industrial controller sells for 615 Euros (Solo version) to 679 Euros (3+ 32GB version) excluding VAT and shipping.
