Flexi-HAL EST Breakout PCBA

Expatria Technologies Flexi-HAL breakout boards.

These simple boards were developed with community feedback to make it easier to manage the wiring of a machine.  These are meant to connect to the RJ45 connectors on the FlexiHAL controller.  Three breakouts are included:

1) The user switch breakout has pushbuttons and LEDs integrated for RUN, HOLD and HALT.  In addition the DOOR signal is present on the board in the case that the breakout is mounted to the machine enclosure.

2) The limit breakout has four axis limits, plus the two inputs for PROBE and TOOL.  This is the most recent version of the design that has better compatibility with probes that have sub-optimal contact resistance.

3) The small triangular encoder breakout exposes the high-speed inputs from the encoder interface on the Flexi-HAL.  These can for example be used as auxiliary inputs with M66 codes.  The breakout includes a differential transmitter to ensure the best possible signal integrity at high switching rates.

Some 3d printed enclosures for the breakouts are posted to this Github repository:

Some examples of the community enclosures are shown in photos here, but this sale does not include any 3d printed parts.  Only the 3 PCB assemblies are included.

Each BOB is also available separately:
