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

Jargon buster
Plain-language definitions for the technical terms used above.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- RS485
- RS485 is a robust differential serial communication standard often used in factories, farms and buildings where cables may be long or electrically noisy, and it can link many devices on a single pair of wires. When a product lists RS485, it can communicate with industrial sensors, meters and control equipment over longer distances than typical hobby serial wiring.
- SCADA
- SCADA stands for Supervisory Control and Data Acquisition, a type of system used to monitor and control industrial processes from computers or control rooms. SCADA compatibility matters when a device needs to report to or take commands from such a larger central control or automation setup.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
