RP Pi Isolated RS485 Shield

Description

The Raspberry Pi Isolated RS485 is a versatile and robust expansion HAT designed to provide isolated and stable RS485 communication for your Raspberry Pi projects. With its built-in power supply isolation, magnetic isolation, and TVS diode protection, this HAT ensures reliable and secure data transmission, making it ideal for industrial and automation applications.

Key Features:

• Standard Raspberry Pi 40PIN GPIO Header: Supports Raspberry Pi series boards.
• 1-Ch CAN: Adopts MCP2515 controller and CAN transceiver, converts SPI to CAN.
• 2-Ch RS485: Adopts SC16IS752+SP3485 dual-chip combination, converts SPI to RS485.
• Wide Voltage Power Supply: Onboard power conversion circuit supports 8~28V, can power the Raspberry Pi simultaneously.
• Power Supply Isolation: Onboard unibody power supply isolation provides stable isolated voltage, no extra power supply required for the isolated terminal.
• Digital Isolation: Onboard unibody digital isolation for isolating the signal, reliable and jamproof, low power consumption.
• TVS Protection: Onboard TVS (Transient Voltage Suppressor) effectively suppresses surge voltage and transient spike voltage, lightningproof & anti-electrostatic.
• Resettable Fuse and Protection Diodes: Ensures stable current/voltage outputs, provides over-current/over-voltage protection, improves shockproof performance.
