            Strato Pi Max XL and XS Raspberry Pi CM4-Based Controllers
                    Sfera Labs' Strato Pi Max XL and XS are versatile solutions that can adapt to any project's unique specifications
    

Sfera Labs' Strato Pi Max is an extremely versatile industrial server. Based on the Raspberry Pi Compute Module 4, the Strato Pi Max is housed in a compact DIN rail case and is suitable for use in professional and industrial applications where reliability and service continuity are key requirements. Strato Pi Max is offered in two versions: Strato Pi Max XS, which supports up to one expansion board, and Strato Pi Max XL, which supports up to four. Both models embed pre-assembled CM4 boards with up to 8 GB RAM and 32 GB eMMC and can be equipped with a high-performance M.2 PCIe® SSD. Strato Pi Max comes pre-installed with Raspberry Pi Compute Module 4 or Zymbit Secure Compute Module (SCM).

Harness the full potential of Strato Pi Max by combining it with any of these optional X2 series expansion boards: Digital I/O, UPS, CAN and Dual RS-485, and RS-232 and RS-485.

Features

Mounting:

6 (Strato Pi Max XS) or 9 (Strato Pi Max XL) modules DIN rail case

Power supply:

10 V_DC to 50 V_DC 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 and with Zymbit 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 board detection and control

Connectivity:

One 10/100/1000 and one 10/100 Ethernet port
Two USB 2.0 Type-A ports with individual power control and fault detection

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 disable the SSD to boot from the eMMC
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 backup battery
3-axis accelerometer for motion and tamper detection

Up to four internal slots for X2 series expansion boards; each installed board is detected and identified for automatic configuration; can be powered off to save power in standby or low-power modes
Flexible mass storage options: eMMC, high-performance M.2 PCIe SSD
Dual microSD card architecture; Strato Pi Max XL 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, enabling separate OS/data storage, SD
Front panel configurable status LEDs and push-button
Variable pitch piezoelectric buzzer for acoustic feedback
