Description
One module, infinite possibilities
Strato Pi Max is an extremely versatile industrial server, based on the Raspberry Pi Compute Module 4/5, suitable for use in professional and industrial applications where reliability and service continuity are key requirements.
Strato Pi Max comes in two sizes:
- Strato Pi Max XS: 6 modules DIN rail, 1 expansion slot
- Strato Pi Max XL: 9 modules DIN rail, 4 expansion slots
Strato Pi Max can be used for an incredible range of applications, from data acquisition and control, to home and building automation, as well as access control, hotel room control solutions, environmental monitoring, and many others.
Strato Pi Max comes pre-installed with Raspberry Pi Compute Module 4/5 or Zymbit Secure Compute Module (SCM).
An optional Compute Module Antenna Kit can be fitted on the top side of the enclosure and internally wired to the Compute Module.
Harness the full potential of Strato Pi Max by combining it with its expansion boards:
Features
Mounting:
- Strato Pi Max XL: 9 modules DIN rail case
- Strato Pi Max XS: 6 modules DIN rail case
Power supply:
- 10-50 Vdc power supply, on pluggable 5.08 mm pitch terminal block, with surge and reverse polarity protection, and 3.3 A resettable fuse
- Voltage and current monitoring of power supply input voltage and current
Processing cores:
- Compatible with all versions of Raspberry Pi Compute Module 4/5, and with Zymbit Secure Compute Module (SCM)
- Powerful and user-programmable 32 bit Raspberry RP2040 microcontroller based on a dual ARM Cortex-M0+ core clocked at 133 MHz, with 264 kB on-chip SRAM ,16 MB Flash memory and 2 kB SRAM with EEPROM backup. The RP2040 is interconnected to the Raspberry Pi via I²C, USB and UART
- The RP2040 microcontroller handles all housekeeping tasks, including Compute Module watchdog, power management, mass storage boot sequence control and expansion boards detection and control
Connectivity:
- One 10/100/1000 and one 10/100 Ethernet ports
- Wi-Fi with optional external antenna
- Two USB 2.0 type-A ports, with individual power control and fault detection
- Additional connectivity provided by the expansion boards
High reliability and security:
- The hardware watchdog independently monitors the Compute Module, and is capable of performing a full power-cycle of the Compute Module. The hardware watchdog can also control the microSD switch matrix, swapping the boot card in case the watchdog is triggered, or disabling the SSD in order to boot from the eMMC or microSD
- The Compute Module can control the Reset and Bootsel lines of the RP2040, allowing in-field firmware upgrades, but also development and debugging without external hardware
- Internal fan for active cooling, with configurable automatic activation based on current load and internal temperature
- Microchip ATECC608 secure element chip
- Temperature sensors for system temperature monitoring
- Highly accurate real time clock with temperature compensated crystal oscillator (TCXO) and replaceable CR1220 Lithium / Manganese Dioxide back-up battery
- 3-axis accelerometer for motion and tamper detection
More:
- Up to 4 internal expansion slots for X2 Series Expansion boards. Installed boards are detected and identified for automatic configuration. Can be powered off to save power in stand-by or low power modes
- Flexible mass storage options: eMMC, dual microSD, high performance M.2 PCIe SSD
- Dual microSD card architecture (Strato Pi Max XL only). Strato Pi Max routes its two microSD card holders to the Compute Module through a high-speed switching matrix, controlled by the on-board RP2040 microcontroller. Each SD card can be set as the boot card, with the other available as additional storage. This enables for separate OS/data storage, SD redundancy and in-field full-system upgrades. The microSD slots are hidden, and can be accessed opening the case
- Front panel configurable status LEDs and push-button
- Variable pitch piezoelectric buzzer, for acoustic feedback
