The DB-9 male screw terminal Breakout board is a great complement to the HDC-01 Four Axis controller system. It provides an easy way to connect cables to the DB9 male connector
The BOB has a male 9 pin D-Type connector on one end and 3.5mm screw terminals for all 9 pins plus the earth terminal.
Note: These are not suitable for use as stepper motor connectors. Please use the GC-12 Connectors for this application.
