{"title":"RS485 Connector Expansion Shield for LattePanda V1","handle":"rs485-connector-expansion-shield-for-lattepanda-v1","url":"/products/rs485-connector-expansion-shield-for-lattepanda-v1","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.\n\nThe 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.\n\nKey Features\n\n\nSignal & Power Isolation – 2500VDC isolation voltage for safe, reliable communication\n\nBus Protection – Lightning surge and transient voltage protection\n\n12V Power Output – Onboard regulated output for connected devices\n\n120-ohm Terminal Matching Resistor – Switch-controlled for end-of-line termination\n\nStackable Design – Mounts via 12mm copper standoffs without blocking airflow\n\nIndustrial Temperature Range – -40°C to +85°C operating range\n\n115200 bps Baud Rate – Maximum supported by LattePanda V1 TTL\n\n\nSpecifications\n\n\nOperating Voltage – 5V\n\nTTL Level – 1.8V\n\nOutput Voltage – 12V\n\nIsolation Voltage – 2500VDC\n\nBaud Rate – 115200 bps\n\nOperating Temperature – -40°C to +85°C\n\n\nIdeal For\n\nIndustrial RS485 communication with LattePanda V1\nBuilding automation and sensor networks\nPLC and SCADA system integration\nRemote device monitoring and control\n\n\n\nWarning: This shield does not support hot plugging. Always power off before connecting or disconnecting RS485 devices.\n\n\nPackage Contents\n\n1× RS485 Connector Expansion Shield for LattePanda V1\n3× M3 hexagonal copper standoffs (12mm)\n6× M3 round head screws\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3478,"title":"Default Title","sku":"DF-DFR0684","price":42.17,"on_sale":false,"in_stock":true,"available_quantity":97,"option1":"Default Title"}]}
