Introducing Version 3 of the T41U5XBB

Today we are proud to announce the availability of the the T41U5XBB V3. The fasted grblHAL motion controller board just got even better. It is a major upgrade of our best selling board. One of the biggest customer requests was support for 24V. V3 now supports 24V as well as 12V. We have also added a number of features from our RP23CNC motion controller board including on-board 5V generation and a fully isolated limit and control input section.

So, what all is new in V3?

We've added a number of features to make it easier and more flexible for the CNC builder.

• Supports 12V to 24V input.

• Onboard 5V regulator for both on and off board use.

  • Auxiliary 5V output.

  • Provides up to 500 mA of current.

• Reversed power polarity protection.

• Fully isolated Limit, Probe and Control input section.

  • Can be powered separately for full isolation.

  • Can also be joined to the main board power section for an economical build.

• Two UARTs

  • UART1 has 3.3V/5V voltage translation and dedicated ESTOP pin.

  • UART2 is 3.3V only.

• Lathe support. Spindle Sync now has a more accessible board level configuration

• Alternate 2.54mm pin header footprints for the screw terminals.

• Ground plane exposed to mounting screws for better integration with a star ground configuration.

Where can I get it?

The T41U5XBB is available on our web store.
