Product description
UART-to-RS-232 breakout board with level conversion and a D-SUB-9 male connector. Ideal for connecting to vintage electronics and older telecoms and industrial equipment. Based on the MAX3243 chip from Texas Instruments, for maximum reliability at speeds of up to 250 kbps.
RS-232 is an old standard used in many different contexts, including data transmission and control. Before USB it was commonly used for devices such as computer mice, modems, keyboards and printers. Equipment with RS-232 is even manufactured today.
The board provides access to all 8 data pins, so you can use flow control signals such as RTS, CTS, DTR, DSR, DCD and RI. There are also two additional connections to the MAX3243: VALID and OFF. VALID provides a high logic level when the circuit detects signal voltages from the device to which it is connected. OFF is used to control the circuit, setting all pins to high-impedance mode.
The header has a breadboard-friendly 2.54 mm pitch.
Supplied with pin headers (not mounted).
