Description
The module converts signals transmitted on the serial UART interface (RX, TX) to the frames of the Protocol RS485. The converter operates in the half-duplex mode 2-directionally, but only in one direction at the same time. Works with voltages of 3 V and 5.5 V.
Connection
The outputs are appropriately marked on the board.
