Description

The Strato Pi Base board enhances the Raspberry Pi computer with several hardware features to make it suitable for use in industrial and professional applications where reliability and service continuity are key requirements.

This add-on board is the the core of our Strato Pi Base server and Strato Pi Touch Display and can be purchased separately for product evaluation, prototypes developments, or custom embedded designs.

Features

Mounting:

  • standard Raspberry Pi 40-pin GPIO header
  • power supply and serial connections on screw terminal block

Power supply:

  • 9-28Vdc power supply, with surge and reverse polarity protection, and 2.2A resettable fuse
  • up to 4.0A max current to the 5V Raspberry Pi power supply input pins (at 24Vdc)

Serial interfaces:

  • standard RS-232 and RS-485 interfaces to the Raspberry Pi serial line, with opto-isolator and electrostatic discharge protection

High reliability and security:

  • hardware watchdog implemented in the Strato Pi board, fully independent from the Raspberry Pi, controlled via GPIO
  • real time clock (RTC) with replaceable back-up battery
  • embedded Microchip ATECC608A secure element chip
  • integrated boot loader for the Strato Pi micro-controller, allowing in-field firmware upgrades directly from the Raspberry Pi

More:

  • buzzer, controlled via GPIO
  • LEDs for power supply and serial line activity
