RS485 3 click

MIKROE-2821 SN65HVD31DR

UART to RS422/RS485, 3.3V

RS485 3 click is an RS422/485 transceiver Click board™, which can be used as an interface between the TTL level UART and the RS422/485 communication bus. It features a 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, thermal shutdown, and more. 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 ±16-kV Human Body Model (HBM) electrostatic discharges.
