BL3085A Datasheet

Efficient RS485 Communication Module: Enhance Your System's Performance

The 7Semi RS485 to UART Transceiver Breakout, featuring the BL3085A IC, is engineered for stable and low-power RS-485 data transmission. This high-performance module ensures seamless communication with a single driver and receiver per device. Its slew-rate-limited driver effectively reduces electromagnetic interference (EMI) and prevents signal reflections from improper cable termination, ensuring smooth data exchange at speeds up to 250kbps.

Designed to support up to 256 transceivers on a single RS-485 bus, this module boasts a high receive input impedance, making it suitable for large-scale applications. Its robust build includes ±10kV electrostatic discharge (ESD) protection for enhanced durability. The integration of a 3-pin terminal block and a 2.54mm pin header allows flexible connectivity with various hardware platforms. This transceiver breakout is ideal for industrial automation, building management systems, embedded networking, and IoT communication modules.
