As for the Educational Kit, it will include the main elements below:
- 1 P-brick
- 1 Rechargeable battery
- Set of RJ-12 cables
- 2 Large servo motors
- 1 Medium servo motor
- 2 Touch sensors
- 1 Color sensor able to detect six colors and absence of color
- 1 Ultrasonic sensor
- 1 Gyro sensor
- Ball Wheel
Thus we will find the Infrared seeker sensor and Infrared "beacon" only with Retail Kit, and the Ultrasonic sensor and Gyro sensors only available with the Education Kit. At least at an initial phase.
Bellow a brief explanation on the main elements and sensors which are expected on EV3 kits.
Got an extra output port (to connect an extra motor - now up to four) and it is half stud thicker.
The display got larger and has higher resolution (178x128px) for larger and more detailed graphics (loved the eyes expressions used in the models above), but still monochromatic... Here LEGO seems not going side-to-side with the latest EVolutions and actuality.
However I would dare to say, to my eyes it shouldn't be very difficult or unlikely, this could become the subject for an upgrade in the next HW revision (typically with a new minor release in about 2/3 years).
It is powered with AA batteries or with an EV3 rechargeable DC battery.
The cables and connectors in use, are the same as in the previous generation (NXT) which sums as a positive.

There is a new rechargeable battery and you cannot use the old NXT batteries because of the different clips on the side (2). Although it uses the same 10v DC power adapter..
Unfortunately the battery pack is again one module higher, thus you'll need to consider this in your models if you plan to use the same robot with and without rechargeable pack...
This battery has a capacity of 2050 mAh and has a charge time of around three to four hours.
As before it can be charged without taking the model apart.

Here we got a large servomotor similar to that with previous NXT version, which also seems to fit into a larger envelope (approximately 14x7x5 modules against 14x6x5 formerly).
Attachment points changed places somehow, when compared to the previous version too. Also they have now a O+O connection shape (hole-pin-hole).
Hope the larger size brings some advantages though...
Some say the connection points at the back align with the center of the rotating output hub, which should make building easier. I'm not convinced of the cost/benefit will be that positive.
The motor shape is also too much faceted to my taste... Don't like it and can't really understand the direction taken here.
- 160-170 RPM
- Running torque of 20 N/cm
- Stall torque of 40 N/cm
- Encoders with 1 degree resolution
- Auto-ID built into the EV3 Software
- LEGO Education listed spare price: $21,95
Finally we got the so desired MINDSTORMS medium motor, based on the same sized PF M-motor but appended with the space required to accommodate an encoder and the MINDSTORMS electrical connector. Of course it is a servo as it won't make any sense otherwise, into robotics kit...
It goes with a 3x4x9 modules envelope. Or 3x3x7 if we strip the MINDSTORMS electrical connector and bottom connector beams, which comes closer to the 7L PF L-motor and to the 6L PF M-motor.
It uses the same type of connectivity possibilities as in the new PF L-motor, although just in the front side.
Like its bigger brother, it also exhibits the new O+O (hole-pin-hole) connectors doubled at the bottom side.
The EV3 Medium Servo Motor is great for lower-load, higher-speed applications and when faster response times and a smaller profile are needed in the robot’s design.
- 240-250 RPM
- Running torque of 8 N/cm
- Stall torque of 12 N/cm
- Encoders with 1 degree resolution
- Auto-ID built into the EV3 Software

Very similar to the previous NXT version, there is not much to say about this, one.
Precisely detects when its front button is pressed or released and is able to count single and multiple presses.
Like several of the other EV3 sensors, I'm not sure whether this is a bit wider then the traditional 3L, because of the side "panel". Although I don't know what is it for or which is its function.
- Pressed / Not Pressed
- Cross axle hole on button
- Auto-ID built into the EV3 Software
- LEGO Education listed spare price: $19.95
It distinguishes between seven different colors and can also detect the absence of color. It also serves as a light sensor by detecting light intensities.
- Measures reflected red light and ambient light from darkness to very bright sunlight
- Capable of detecting seven colors plus the absence of color. It can tell the difference between color or black-and-white or among blue, green, yellow, red, white, and brown
- Sample rate of 1 kHz
- Auto-ID is built into the EV3 Software
- LEGO Education listed spare price: $34.95
Available with the Educational EV3 Kit, this digital sensor measures the robot’s rotational motion and changes in its orientation.
- In angle mode, measures angles with an accuracy of +/- 3 degrees per 90 degrees turned.
- In gyro mode, it measures a maximum of 440 degrees per second.
- Sample rate of 1 kHz
- Auto-ID is built into the EV3 Software
- LEGO Education listed spare price: $29.95
The digital EV3 Ultrasonic Sensor generates sound waves and reads their echoes to detect and measure distance from objects. It can also send single sound waves to work as sonar or listen for a sound wave that triggers the start of a program.
- Measures distances between 1 and 250cm
- Distances are return in 0,1cm resolution but accuracy is about +/- 1cm
- Front illumination is constant while emitting and blinks while listening.
- Returns True if other ultrasonic sound sensor is recognized (listen mode)
- Auto-ID is built into the EV3 Software

The digital EV3 IR Seeker Sensor detects/measures proximity to the robot and reads signals emitted by the EV3 IR Beacon..
- Proximity measurement of approximately 50-70cm
- Can be used as a receiver for the IR Beacon
Can also receive IR remote commands - Can measure the direction to the IR Beacon
- Working distance from the beacon of up to two meters
- Supports four signal channels
- Auto-ID is built into the EV3 Software
- LEGO Education listed spare price: $29.95
This has been designed for use with the EV3 IR Seeker Sensor. The beacon emits an infrared signal, which the sensor can track. The beacon can also be used as a remote control for the EV3 Brick through signals sent to the infrared sensor.
- Requires two AAA batteries
- Four individual channels
- Includes a beacon button and toggle switch to activate/deactivate
- Green LED indicates if the beacon is active
- Auto power-down if the unit is not in action for one hour
- Working distance of up to two meters
- Can act like a beacon for homing routing
- Can be used to to control your robot with buttons - a little like the PF IR remote control.
Wonder how the red/blue buttons and the four channel switch, operate together with the robot(s) and respective output ports - LEGO Education listed spare price: $29.95
