DB9 Vertical Female Breakout Module to Screw Terminal + Pin Header

From the shop's description

DB9 Vertical Female Breakout Module to Screw Terminal + Pin Header The DB9 Vertical Female to Screw Terminal + Pin Header is a compact PCB breakout that converts a standard DB9 female serial connector into both a 2.54mm pitch pin-header and 3.5mm pitch screw-clamp terminals, making it simple to connect, test or prototype RS-232 and serial circuits without soldering directly to the connector. The board is clearly silkscreened with DB9 pin numbers, includes mounting holes for secure installation, and is ideal for bench work, test fixtures and quick field wiring tasks. Features DB9 pins are routed to pin headers and screw clamp terminals. Both terminals are labeled according to the DB9 pin number to which they are routed. Pin header pitch distance 2.54mm. Screw terminal pitch distance 3.5mm. Four (Ø 3.5mm) mounting holes for easy installation. Dimensions: 50 X 30 X 25mm. Specifications Parameter Value Connector Type DB9 vertical female to pin header & screw terminals Pin Header Pitch 2.54mm Screw Terminal Pitch 3.5mm Mounting Holes 4×Ø3.5mm Dimensions 50mm x 30mm x 25mm Applications Solderless breakout for RS-232/serial connector debugging and prototyping. Quick wiring of serial devices in test fixtures, bench setups or temporary installations. Converting DB9 signals to breadboard-compatible headers for development and education. Field wiring where screw-terminal convenience is preferred over solder connections. Small control panels and enclosures requiring a compact DB9 interface breakout.
