To implement the RS232 communication standard on the MCUs, it is necessary to convert the voltage levels to the levels acceptable for the modern MCUs. The RS232 2 Click Board™ performs full RS232 to UART signal conversion, allowing both 3.3V and 5V operation. Additionally, it features 15 kV ESD protection for the RS-232 I/O pins.
These attributes make the RS232 2 Click Board™ a perfect solution for battery-powered, hand-held and portable equipment, PDAs, palmtops, digital cameras, and other devices that still support the RS-232 standard.
