This industrial-grade RS485 expansion shield from DFRobot is designed to add two parallel RS485 terminal ports to LattePanda Alpha, LattePanda Delta, and LattePanda 3 Delta boards with high reliability. This RS485 expansion shield is the perfect solution for LattePanda Alpha and LattePanda Delta users requiring robust serial connectivity.
Equipped with an FTDI USB-to-serial chip and an industrial-grade isolated transceiver module, the RS485 expansion shield provides signal and power isolation, lightning/surge protection, transient impulse voltage resistance, and bus protection. This ensures stable and secure RS485 communication in industrial environments while protecting your LattePanda Alpha or LattePanda Delta mainboard.

The RS485 expansion shield features a stackable design, allowing for secure mounting on the LattePanda Alpha using copper pillars without obstructing the LattePanda Delta mainboards heat dissipation area.
