MIKROE-2821

RS485 3 an RS422/485 transceiver Click board™ used as an interface between the TTL level UART and the RS422/485 communication bus. It is well suited for transmitting data packets over long distances and noisy areas, using the four-wire bus allowing for full-duplex communication. Internal ESD protection circuits protect the transceiver bus terminals against ±16KV Human Body Model (HBM) electrostatic discharges. Suitable for use in controlling various building automation systems, light controllers, sensors and small embedded devices that can all share the same bus.

• Full-duplex communication capability
• Bus idle, open and short-circuit detection
• Glitch free power-up and power-down for hot-plugging applications
• Driver current limiting and thermal shutdown
• Hot plug capability
• UART interface
• 3.3V input voltage
