RS485 Connector Expansion Shield for LattePanda V1

The RS485 Connector Expansion Shield provides industrial communication capabilities for the LattePanda V1 single-board computer. Designed for makers, engineering students, and developers, it enables robust long-distance data transfer in automation and instrumentation projects.

Stackable LattePanda V1 design

This shield features a stackable form factor designed specifically for the LattePanda V1. It connects directly to the board while maintaining a compact, neat assembly for embedded builds.

2500VDC electrical isolation

Integrated 2500VDC isolation separates the LattePanda logic from the RS485 communication line. This prevents ground loops and safeguards the host computer against high-voltage faults.

Onboard surge protection

Built-in surge protection defends signal lines against transient voltage spikes and electrical noise. This ensures stable and reliable communication across noisy industrial or workshop environments.

Standard 120-ohm terminal resistor

The board incorporates a 120-ohm termination resistor directly across the RS485 differential lines. This reduces signal reflections and maintains data integrity over extended transmission distances.

Dedicated 12V power output

An onboard 12V output provides auxiliary power for external sensors and RS485 peripherals. This reduces cable clutter by removing the need for a separate external power feed.
