DB9 RS232 Breakout Board with Case

This DB9 breakout board converts a serial D-SUB port to screw terminals for solder-free wiring. The module ships inside a protective case and accepts wire gauges from 12 to 24 AWG. It is aimed at engineers and hobbyists who need a quick, reusable RS232 connection for test benches or field repairs.

Suits bench prototyping and permanent panel mounting

The screw terminals and compact case make it practical for both temporary breadboard work and fixed installations in enclosures. Buyers who need a cable-assembly solution with pre-crimped connectors or a right-angle DB9 orientation should look at a different adapter style.

Handles standard RS232 signal wiring

The terminal block accommodates solid or stranded wire in that gauge range and the gold-plated contacts maintain reliable conductivity. The 10 mm cable entry and 3 mm mounting holes support panel fixation, while the ABS plus PC case provides insulation and strain relief for permanent deployments.
