The TETRIX® PRIZM™ Robotics Controller is a fully integrated, programmable brain for your bot that features a variety of motor, servo, encoder, and sensor ports with convenient connectors that enable you to control your robot's behavior like never before. This controller offers the best of both worlds – a learning tool that is powerful yet easy to use. With PRIZM you can take learning to new heights by creating robots that are smarter, more precise, and as real world as it gets.

The controller is specifically developed for use with the TETRIX MAX building system and comes with programming support for the Arduino Software (IDE), which is compatible with Windows, Mac OS X 10.7 or newer, and Linux devices that have a USB port.

The PRIZM Robotics Controller features:

  • 32 KB flash programmable memory
  • ATmega328P processor with Arduino Optiboot bootloader installed
  • 4 digital sensor ports (D2 can be used as a serial port) and 3 analog sensor ports
  • 1 I2C port, 1 USB programming port, 1 motor controller expansion port, and 2 quadrature encoder input ports
  • 2 high-current DC motor control ports
  • 6 standard control servo ports and 2 continuous rotation (CR) servo ports
  • Battery connection port (additional port used to daisy-chain power to other devices)
  • Programmable Start button (green) and a non-programmable Stop/Reset button (red)
  • Comes with USB cable, power switch, motor cables, and a Quick-Start Guide


Get programmable control while keeping your robot looking clean and tidy.

The TETRIX® Autonomous Mounting Deck features precut holes to make it easy to mount an Arduino or Parallax Basic Stamp programmable controller to a TETRIX robot, as well as the TETRIX DC Motor Speed Controller.

The deck is sized to fit the TETRIX hole pattern spacing so it can be used on a variety of robot designs. Made from 1/8" black acrylic and measures 6.25" x 3.75". Includes screws, nuts, kep nuts, and acrylic spacers for mounting components.

$15.95 $10.95

Attach an R/C receiver and R/C speed controller to the TETRIX® hole pattern. Plastic decks are attached using screws and nuts included in the TETRIX starter sets. Kit includes two plastic mounting decks and a hook-and-loop fastener.


Keep your R/C robot components looking neat and professional with this mounting deck.

The TETRIX® R/C Mounting Deck was designed with precut holes and slots to make it easy to mount and neatly secure all the components necessary for controlling a TETRIX robot with an R/C radio receiver, TETRIX DC Motor Speed Controller, switch, and four-cell battery holder (all sold separately).

Sized to fit the TETRIX hole pattern spacing, the deck makes for easy attachment to a variety of robot designs. Made of 1/8" black acrylic and measures 6.25" x 3.75". Comes with 12 zip ties and a 6" piece of hook-and-loop fastener for attaching components.


The HiTechnic DC Motor Controller for TETRIX® connects to an EV3 Intelligent Brick sensor port and enables you to control powerful DC motors for use with TETRIX robots. The controller has two H-bridge outputs to control the speed and direction of two DC motors and is designed to connect to the TETRIX hole pattern.

$89.95 $75.00

The HiTechnic Servo Motor Controller for TETRIX® connects to an EV3 Intelligent Brick sensor port and enables you to control up to six R/C-type servo motors for use with TETRIX robots, enabling you to add proportional positioning to your robotic creations.

$79.95 $65.00

Take control of your TETRIX® DC motors – this controller plugs into your TETRIX wireless gamepad receiver to enable you to control the speed and direction of two TETRIX 12-volt DC motors.


This pack contains a line-tracker module that transmits a digital signal to the TETRIX® PRIZM™ Robotics Controller, enabling a robot to follow a black line on a white background or vice versa. The sensor consists of two parts: an IR-emitting LED and an IR-sensitive phototransistor. Comes with a mount, connecting sensor cable, and the hardware needed for attaching the sensor to the TETRIX hole pattern.
