ERR Mini Commander


(1 customer review)

All version in stock!!

Five versions of the Mini-Commander are available!  See additional information provided with specific Option.  Setup is via Soft Set technology or Run/Pgm Switch.  Each unit is only 1″ x 2″ footprint allowing easy placement in rolling stock, dummy engine, or track-side accessory.

Mini commander has two versions for Accessory (HC version special order) or to support a dummy engine (EX).  All four outputs can be set to a voltage output for motor, solenoid, smoke, or light control.   There is a Serial signal output, but an additional Serial Buffer is required to drive an ERR Sound kit.  Contact us if you have questions.  Can also be used to control rolling stock accessories!

The Mini Commander 2 has variable DC output for motor control via the TMCC speed control and sync for sound.  The Mini-Commander 2s are available with motor control and

  1. With directional lighting control,
  2. With directional couplers control
  3. With smoke unit and headlight control

All three versions support directional LEDs with on board regulation.  In addition, the MiniCommander2’s can also provide serial data output to drive an ERR Sound kit.

Applications include small engine control, Turntable control, motor driven bridge control.


All Mini-Commanders are In Stock.  Each of the ERR Mini-Commanders is a full TMCC controlled board designed for a specific purpose.  They can also drive an ERR sound kit but the MiniCommander ACC & EX require the Serial Buffer!  The MiniCommander HC is available on special order;  contact me directly.  If you are not sure which version you need, feel free to contact me.  These are for limited current applications which include motor, lamps, couplers, smoke, and sound.  The MiniCommander2 units are the only version that supports variable motor speed directly and directional LEDs with on board regulation.

These commanders can be used for turntable control, bridge control, general motor control in accessories, and smaller can motors in some engines.  The ACC version has been used for signal man caboose, remote control of Atlas switches, Lionel accessories and many others!  The limit is the current requirements of the motor to be controlled!

    Roy helped me select this unit for my caboose upgrade! With a little support I was able to upgrade my MTH caboose with signalman. Works to operate the signalman out/in movement and turn on his lantern! Thanks.
