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 wired serial communication standard often used in factories, farms, and buildings where cables may be long or electrically noisy. It matters because it lets this controller connect to industrial sensors, meters, and control equipment over longer distances than typical hobby serial wiring.
- SCADA
- SCADA means Supervisory Control and Data Acquisition, a type of system used to monitor and control industrial processes from computers or control rooms. SCADA compatibility matters if the controller will be part of a larger automation or monitoring 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.
