Mainboard

Description

The Mainboard is the core of the NOREYA Nexus platform providing six extension slots for modules.

The key features are:

Software

• NOREYOS is based on Debian (ARM64)
• Supports full configuration via a web application.
  • System settings and information
  • Installation of various smart home software
• Bootloader & Firmware update support.
• Programmable via the Module RESTful API
  • Supports voltage, temperature, watchdog, USB hub & bootloader and buzzer.
  • Simple programming example (Python)
• No vendor lock, boots Raspberry Pi Compute Module compatible software

Hardware

• Based on the Raspberry Pi Compute Module 3+
  • BCM2837B0, Cortex-A53 (ARMv8) 64-bit SoC @ 1.2GHz Quadcore
  • 1GB LPDDR2 SDRAM
• 6 expansion slots each with SDBP and USB support.
• 1 power supply expansion slot.
• 2 microSD card slots with 64 GB storage and RAID-1 support.
  • Failsafe against microSD card wear and tear.
• USB hub with per-port power control and overcurrent detection.
• Supports automatic detection by the USB descriptor.
• Integrated real-time clock (RTC) with CRC2032 battery.
• Serial console via USB port (C).
  • Supports USB mass storage mode “boot and reset after timeout” for easy data access.
• Buzzer for simple audio signals
• IEC/EN 60715 – 35 (35mm DIN rail) mounting options
• Operating temperature (ambient air) range 0°C – 50°C.
• Storage temperature range -20°C – 60°C
• Baseboard Management Controller (BMC)
  • Watchdog function
  • Supports low level configuration of USB hub
  • On-board voltage measurement
  • 2 temperature sensors (free ambient / SoC ambient temperature)
  • tactical hardware switch for factory reset and booting in USB mass-storage mode boot
  • 3 hidden switches (requires screw driver for switching)
    • BMC write protection on/off
    • BMC bootloader enable on/off
    • RTC battery connected/disconnected

Important notes

• Device is configured via serial console (USB jack C) (no keyboard/mouse support).
• Display output is only supported for debugging (no official support for graphical applications!)
