Design a Custom BoardAbout This Component
Half-duplex RS-485 transceiver supporting multi-drop serial communication. Operates at 3.3V or 5V logic levels with integrated termination bias resistors and fail-safe biasing. Ideal for industrial automation, building control, and long-distance twisted-pair networks requiring robust noise immunity.
Package: MSOP-8 · 8 pins
Why does this need a breakout?
The 0.65mm pitch and tiny 3×3mm form factor make hand soldering challenging and impractical for breadboard prototyping. A breakout board converts this compact SMD package into a standard header layout, enabling reliable connections and rapid iteration without specialized soldering equipment or rework risk.
