K40 Adaptor Board v2 (kit)

Now in stock!!

This breakout board v2 kit helps with connecting your K40 laser to replacement controllers with screw terminals.  The photo shows the finished product, but it’s a kit so you’ll need to solder all the connectors yourself.

It’s ideal for connecting your own controller to your K40. All connections are labelled, and the whole board can be neatly mounted with 4 included adhesive stand offs. It includes:

• X and Y 4 pin stepper motor terminals
• Ribbon cable connector (including connections to X stepper motor and limit switches)
• Limit switch connector
• Large 4 pin connector for 24V, GND, 5V and LO
• 4 pin control connector for water protect, pause, resume and PWM

The layout is improved over previous version.

Please see photo below showing both board sides for connections. Please check the board connections suit your purpose before ordering. Note the lower board photo is reversed to allow easy tracing of connections.

The kit includes two types of connectors for the three 4 pin connectors: a JST type which accepts a mating connector only in one orientation, and a generic ‘locking’ style header which supports one orientation (but in practice allows the reverse orientation). If you’re 100% sure which orientation you need, use the JST so that you can only ever plug things in the right way in the future. If you like a bit of flexibility, go for the locking style connector.

You don’t need this board when you buy a Mini Gerbil since this controller has all the K40 type 1 and 2 connectors on board.

Note that version 2.1 of the adaptor board contains a small error – there is a missing track joining to the X limit connection. Fortunately, this is easily solved by the end user soldering an insulated wire between the relevant solder joints.
