This Ultimate Breakout Board just made EVERY OTHER BREAKOUT card on the market OBSOLETE!

    17 outputs,  9 inputs.  All outputs buffered - 8 double buffered, a ll inputs isolated; all from a Single Parallel Port.

    The big problem in the past is a single p ort BOB left you with 4 axis of S&D, 1 Charge Pump and 3 general purpose outputs (total of 12 outputs).  Even worse, you only had a total of 5 inputs and one of those had to be E-stop!   We solved the problem by building a PORT  S T R E T C H E R!  It uses advanced TDM MUX techniques to STRETCH the lower speed outputs to 8 (and can drive a relay up to 100ma) and still have four full axis of movement.  Even more important, we STRETCHED the inputs to 9 fast inputs that will work for homes, limits, probes, sensors or other general input signals.  Before, when you wanted to do extra functions,  you had to play games and string all of the homes and limits together to get more input pins.  The UBOB solves the problem!


    • Single cable solution.
    • 8 high speed outputs for S&D.  8  low speed outputs for general extrernal control.  Open collector buffered outputs for up to 6 relays (in addition to torch relay and direction relay on DTHC or ISS-02 modules).
    • 9 Isolated Fast Inputs for h omes, limits, probes, external sensors, etc. 
    • Charge pump output.
    • Charge pump indicator.
    • Plugs directly into our MTA150 for interface to various motor driver options.
    • Provides clean, buffered (full 5V TTL logic) signals for Step and Direction with 3 volt inputs.
    • Board mounted DB25 uses ONE standard M-F computer cable.
    • Board mounted serial port (DB9) for pass through communications to our other smart cards.
    • Features expansion plug for Digital Torch Height Controller or Isolated Spindle Speed Controller. 
    • Compact SMT design minimizes mounting footprint to 2.75 X 5.0 square inches.
    • Uses external +12 supply.
    • Has on-board DC-DC converter for TRUE isolated input (separate from Logic/PC ground).
    • Only BOB that allows you to hardware slave X or Y to run 5 motors and 4 independant axis.
    • Hardware polarity (DIR) for slaved axis.
    • Comes with 25 pin expansion cable for external I/O  (to remote Table I/O card ).
    • Available custom mounting plate for mounting in your enclosure (see MP3000 section).

The individual cards are offered for sale to allow maximum flexibility BUT for the normal build the Plug-n-Run controllers are recommended.  They give you all of the cards and cables you need.  Expansion cards can be added later or to provide advanced features.   Some cards are avaialble here as spares or replacement cards for out-of-warranty units.

NOTE: as of 2/25/2012 the UBOB Builders Paks are no longer available.  The MP3000-Basic or MP3000E-DTHC II is available in an OEM Builders Version (right angle plate with front panel.  It comes assembeld on standoffs with Table I/O, power pak, UBOB III and DTHC II (option) wired and tested, ready to mount in an enclosure.  The cards listed below are to expand an existing build or for spare cards for an existing unit.

Cards that give you added functions or features. 


Used For:




Full Digital Torch Height Control Expansion Module

HUH?  What's this?  Because the DTHC is now a tiny plug-in module you can make ANY UBOB based product into a full blown Digital Torch Height Control.  Comes with a matching THC Sensor Card for interface to your plasma cutter.
NOTE:  YOU CANNOT HAVE A ISS-O2 SPINDLE SPEED AND DTHC-Expansion Module plugged in at the same time.

With THC Sensor card and cables




NOTE:  There are NO screw terminals on the UBOB for connection to external signals You must use the MTA150 card for motor drive interface and the Table I/O card for connecting any inputs or outputs


The Ultimate Breakout Card for use with MACH3 Software.  Matching plug-in for MACH and custom driver loads automatically from the Install Disk.  Suddenly you have more inputs and outputs....often enough to keep from adding a second port.  One 25 pin computer cable does all the work.  Unit needs +5 volts referenced to PC Ground and +5 to +12 with separate ground return (floating).  Both supplies 500 ma or more.  Note: serial port not needed for basic UBOB operation but is need for expansion products like the ISS-01 and DTHC cards.

CARD SOLD FOR REPLACEMENT OR SPARE ONLY.  THIS IS NOT A General Breakout Board (BoB)  and requires other cards for a complete BoB solution.  See the MP3000- Basic.











This card was the shipping card with all older DTHC units.  It has enhanced balanced Twin-T LC noise filter, improved high voltage tolerance, intergal Arc Gap and input polarity protection.  It is plug compatable with older CandCNC MP1000 THC boxes.  Developed to provide reliable operation for HF start and the more difficult High Voltage (CD) start units like the larger ESAB units, it has proven itself virtually indestructable.

NOTE:  THE NEW DTHC II DOES NOT USE THIS CARD.  It uses a completely different method of interface to the Plasma Unit.  The THC SENSOR REV15 is for replacement of any existing REV 8 - 15 THC SENSOR cards used with the MP1000 or MP3000-DTHC (or LCTHC) products.






Designed to plug into the UBOB card and mount anywhere from a few inches to several feet away, it uses conventional relays so you can power AC or DC loads, wi th or without Softstart.

Status LED's for visual confirmation of signals.

Basic I/O card has 8 inputs and 2 power relays for outputs.  Plugs into IDC header on UBOB via IDC to DB25 plug so it can be mounted remotely for easy connection of table switches and AC loads.  Primary relay supports up to 20A  @ 275VAC.  Expanded inputs and outputs available at the UBOB card.

It does have a DB9 connector and 10 pin ribbon connector to interface to our QUAD RELAY CARD. 

Perfect low cost card for providing spindle control and aux power via the two power relays.  Large 20A relay will handle most AC loads.

If you expand with the PORT2 interface card, there are 5 addtional inputs on the Table I/O available.



MTA150 Cable Interface Card

Provides a single cable interface with plugs and terminals to support either hard wiring (via screw terminals) to motor drivers or through multi-conductor cables, a single plug interface to our EZPlug series of Gecko Interface.  If you are using another brand of drives (up to 5) you can use the screw terminals.  Illustrated manual shows how.  FOR USE WITH UBOB or UBOB based products (MP3000) ONLY!
