Sfera Labs has introduced an industrial Raspberry Pi-based edge server and PLC for industrial IoT and edge applications. The Strato Pi Plus server and Iono Pi v3 controller come in DIN-rail enclosures with an embedded Raspberry Pi 4 or 5 single-board computer (SBC), delivering industrial-grade systems for automation, field communications, and IoT edge deployments that require continuous, unattended operation.
The Strato Pi Plus features a hybrid architecture that pairs the Raspberry Pi SBC with an RP2354 MCU. The RP2354 operates independently of the main processor to manage critical real-time functions and system supervision, including an independent hardware watchdog. In-field firmware updates for the RP2354 are supported via OTA, managed directly through the Raspberry Pi. Serial connectivity includes four individually opto-isolated RS-485 ports and one CAN FD interface. The Strato Pi Plus operates from an integrated 10–50 V DC supply with surge and reverse-polarity protection and a 3.3 A resettable fuse.
The Iono Pi v3 industrial PLC integrates a 9–28 V DC power supply, four power relays, high-resolution analog voltage and current inputs, and seven configurable GPIO pins. Like the Strato Pi Plus, it implements a hardware watchdog in the RP2354 MCU that operates independently of the Raspberry Pi SBC. The device also includes a real-time clock with a temperature-compensated oscillator and replaceable backup battery. An embedded Microchip ATECC608 secure element enables hardware-based authentication and cryptographic key storage.
A timeline for availability of the Strato Pi Plus and Iono Pi v3 was not provided at the time of this announcement.
