Sfera Labs Strato Pi CAN Board

Sfera Labs Strato Pi Controller Area Network (CAN) Board enhances the Raspberry Pi Model B version 2 and 3 computers with several hardware features. This board makes the Raspberry Pi computers suitable for professional applications where reliability and service continuity are key requirements. This board comes with all connectors pre-installed and requires no soldering. The Strato Pi CAN board is connected to the Raspberry Pi by aligning the GPIO connector. Appropriate turrets/spacers are used to bolt the two boards together firmly.

The Sfera Labs Strato Pi CAN Board incorporates a real-time clock, ATECC608A secure element chip, RS-485 port, CAN port, buzzer, relay, and hardware watchdog. The CAN interface is based on the Microchip MCP2515 stand-alone CAN controller that implements the CAN specification version 2.0B.
