RS232 click

RS232 click is a simple solution for adding RS232 connectivity to your design. RS232 is a serial communications standard mostly used for industrial machines, networking equipment and scientific instruments, as well as for computer peripherals. The board features a standard RS232 DB9 port and a MAX3232 IC, along with a mikroBUS host socket, three jumpers and a power indicator LED. RS232 click communicates with the target board through mikroBUS RX (RXD), TX (TXD), CS (RTS), and INT (CTS) lines. RS232 click is designed to use either a 3.3V or 5V power supply.
