## Description

An industrial-grade RS485 expansion shield designed specifically for the LattePanda V1. This shield adds a reliable, isolated RS485 interface (via OPEN4) with comprehensive protection including signal isolation, power isolation, lightning surge protection, and transient voltage suppression — keeping your LattePanda safe in demanding industrial environments. The stackable design mounts directly onto the LattePanda V1 using copper standoffs without blocking the heat dissipation area. An onboard 120-ohm terminal matching resistor (switch-controlled) and 12V power output make it ready for real-world RS485 communication deployments. Key Features Signal & Power Isolation – 2500VDC isolation voltage for safe, reliable communication Bus Protection – Lightning surge and transient voltage protection 12V Power Output – Onboard regulated output for connected devices 120-ohm Terminal Matching Resistor – Switch-controlled for end-of-line termination Stackable Design – Mounts via 12mm copper standoffs without blocking airflow Industrial Temperature Range – -40°C to +85°C operating range 115200 bps Baud Rate – Maximum supported by LattePanda V1 TTL Specifications Operating Voltage – 5V TTL Level – 1.8V Output Voltage – 12V Isolation Voltage – 2500VDC Baud Rate – 115200 bps Operating Temperature – -40°C to +85°C Ideal For Industrial RS485 communication with LattePanda V1 Building automation and sensor networks PLC and SCADA system integration Remote device monitoring and control Warning: This shield does not support hot plugging. Always power off before connecting or disconnecting RS485 devices. Package Contents 1× RS485 Connector Expansion Shield for LattePanda V1 3× M3 hexagonal copper standoffs (12mm) 6× M3 round head screws
