An industrial-grade RS485 shield for LattePanda! It is designed to expand a reliable RS485 interface(OPEN4) for LattePanda V1. The receiving and sending of the module are isolated and it features signal isolation, power isolation, lightning surge protection, transient voltage resistance, and bus-protection, which assures reliable data transmission and effectively protects your LattePanda main-board. Apart from that, the module offers 12V power output and comes with on-board 120Ω terminal matching resistor that can be controlled by the switch.

The product employs a stackable connection, which makes it able to be easily fixed onto LattePanda main-board by copper columns without blocking the heat dissipation area of the main-board. This RS232 Connector Expansion Shield can be safely applied in industrial scenarios.
