RS485 click 3.3V carries the SN65HVD12 half-duplex, RS-485 transceiver from Texas Instruments.
It is designed for balanced data transmission and complies with EIA standards RS-485 and RS-422.
The click is designed to run on a 3.3V power supply. RS485 5V click communicates with the target microcontroller over UART interface, with additional functionality provided by the PWM pin on the mikroBUS line.
